Homemade test light against the power probe?
Vložit
- čas přidán 6. 02. 2019
- In this video we will be discussing the power Probe's "hot shot" test against a decade box to see sensitivity of test.
Next we move on to talking about the Power Probe "Tip Voltage" using a decade box.
I'll show the advantages and draw backs of the load pro.
Lastly I'll show my homemade test light with stack-able banana jacks so you will be able to load a circuit and take your voltage readings at the same time. - Krátké a kreslené filmy
Very well put together Cody! Great video! The sad truth is many guys still do not understand the importance of loading a circuit for voltage drop testing. I get many vehicles which are misdiagnosed because of using a power probe for these tests. No excuse these days with the internet. Anyone has this information available to them. Keep up the great work brother. Can't tell you how much I enjoyed this!
Great video Cody! Test light FTW. I also have a homemade test light setup with banana jacks and TWO dual filament bulbs in parallel...makes 5 "settings" from 500mA to 5A 😎
@@PineHollowAutoDiagnostics I recall seeing you use them a few times in the past Ivan..Thought that was a great idea, so I made one as well. Lol Thanks for the idea buddy 😀
Joe's Auto Electric I hear ya man! Before I knew better many moons ago I was that guy as well tell properly getting educated 😂 thanks for watching bro!
Exmotorsports that’s when I got this idea after seeing Ivan’s set up too lol
Pine Hollow Auto Diagnostics Ivan I’ve seen yours and loved the idea so much is when I put this together. Can never have to many test lights 😂
i am new to the scope and load testing world im a old timer. once i started watching ya'll what i have done is try to size a test bulb draw to be about the same size load, then watch voltage drop so far has worked for me. i had a 1997 Dakota no start the asd relay would not come on. i checked voltage good check ground good checked pcm ground had ground small test light came on so unplugged pcm and connected larger bulb would not burn computer would ground test light but not bulb. replaced computer truck runs great no problems. but power probe said ground and small test light ground. its a learning curve . i have been testing bulbs and making lights that draw about the same as like fuel pump and use for testing. i know i have to be careful not to damage pcm. thanks for all you do
That’s awesome to hear other guys making tools and also loading a circuit. I did it wrong for years thinking the pp was was properly loading a circuit. Thanks for watching and also for your comment.
Beautiful video Cody. Thank you for illustrating and proving the load theory with a thorough comparison
Thanks brother!
I have been in this field for 44years and set in my ways but you have opened my eyes so much you are good and keep it up
Tony Chandler that means a lot coming from yourself! Thanks for the support and views buddy
Great video Cody! The bulb brightness is great. Always a good test to verify you bulb direct to the battery first 👍🏻 keep the videos coming!
scott pitcher thanks bud and thanks for watching
Very good video! Keep 'm coming!
DiagnoseDan thank you Dan! Appreciate you watching!
VERY STRONG VIDEO ON CIRCUIT TESTING , I PERSONALLY I WILL BE MODING MY LOAD PRO VERY CAREFULLY . THANKS AND PLEASE KEEP UP THE VERY COOL WORK !
8power0 will do bud thank you
Cody I love your channel Brotha! You explain things easy to understand! Man I like the test lights you made! You should do a video on how you do it. It could be a hit! Awesome video!
Thank you Robert! I’ll keep that video idea mind, thank you!
Nice video I pulled this info out of a trouble shooting article and It states,
It doesn't take much of an increase in resistance to cause trouble. Let's say a 120 amp alternator operates in a circuit that has a normal resistance of 0.11 ohms. If that resistance were increased to 0.17 ohms because of a bad wiring connection, the alternator's maximum output would be limited to 80 amps. In other words, an increase of only 0.06 ohms (almost nothing!) would reduce the alternator's maximum output by almost a third! Under light load, the drop in charging output might not even be noticeable. But in a high load situation, the alternator wouldn't be able to keep up.
I noticed on the screen of the Snap-On multimeter that the decadent box with no switches on was at 0.17 ohms of resistance from the get go. So if the information is correct on the electronic trouble shooting article then the Snap On and power probe hook are correct in failing in the hot shot test. Unless I'm missing something. Wishing you and your loved ones well.
Hey buddy thanks for your comment. That’s great information and you are right there was resistance at the very beginning in the box. I’ll have to check my other decade box and see what the reading is and if the pp will show pass or fail. Thanks again
Well done! This was a great video and a huge help to diagnose.
Thanks for watching bud
Great video Cody and 100% on point. Lots of techs still don't seem to understand that open circuit testing is not sufficient. It's important to have multiple tools in your arsenal as well because they all have their place. Like you said, the Power Probe is a great tool but it has its limitations just like anything else. Really glad I found your channel man. Just one more of the great ones out there that allow professionals as well as DIYers to connect to this kind of information. No one of us is as smart as all of us... Except for maybe Keith. 😂
Awesome video. I love comparisons like this. One other issue I've had with the PP is the low internal resistance. When checking an open 5v signal circuit, it kept pulling it down to like 2v. I was fortunate to catch that the ECM was seeing it, and tried my meter on it. No problem with the meter.
Thanks for sharing! Great idea to have the stackable banana jacks. Bought them from the suggestion on the last video of making the test light.
Angel Garcia that’s awesome! Happy to hear that. Thanks for watching
excellent video. I'm also all ears. like I said I'm new to the electronic world but in devting a lot of time and money to learn it. Any video you put out I will watch. Thanks for taking the time to teach. 👍👍👍
Really appreciate all your comments and support buddy, thanks again
Thanks for the videos brotha! Ordered a bunch of banana connectors to make my own wires and to modify my otc test light. Gonna watch your tool box tour for more ideas 💡 😎
Thanks for watching bro
I love this video. One thing I think you failed to mention is prior to relying on the brightness of a test light bulbs brightness, you should always use a direct connection to battery as a reference. Much love, much respect. Thank you for your professionalism in what you do. Im 21 years deep with Chrysler, jeep, dodge, ram and only as of the last 5 years have I realized the importance of the loaded Voltage drop test. Your technique is bad ass.
Thank you so for the kind words! I really should redo this video and explain a little better about loaded circuit testing. I’m still fairly new to making videos lol.
Hi Cody!, My comment is 2 years after this video. I saw the video twice, read all comments. I know close to nothing in terms of Auto Diagnostics. On this covid-19 seclusion I decided to revive a 89 Toyota Cressida that has parked on the side of my drive way for 4 years, I decided to bring this beast to live, for fun. In the process I realized that I need a prob, a device to help me to make decisions on a crank no start situation, so so many variables to eliminate. Then a ordered from Amazon a Power Probe EEZREDAS. After ordering a saw your video. I know that know nothing about Diagnostics, but know quite a bit how to read honesty and compentence, incompetent people usually deceive; Your presentation in this video is so down to earth, honest and competent, so much so that almost everybody left comments saying "great Cody"!. So...3 hours later, after ordering the item from Amazon, I canceled the order because I understood "voltage drop on load", something that Power Probe does show. As a beginner I don't need a tool that would gives FALSE POSITIVES . thank you Cody, I hope you still making videos on Diagnostics, If so, I will listen to you.
Wow Edson this comment made my day! Thank you for the kind words buddy. I’m happy this video helped you along your way.
Excellent Cody you have my attention and subscription

Every tool has its place. I love the banana jacks on the pigtail. I'm stealing that
S & A Auto Repair every tool does Corey! Hints why I don’t get rid of old tools lol
I live in a part of Mexico where the weather is always good, I have been mechanic for almost 13 years now and never had a high resistance circuit problem on anything, but I do see a lot of imported cars and trucks from snowing states over there and I know some day I will have to deal with high resistance problems.
I saw many times the use of of these diy test lights but never being interested on making one, but after your very, very instructive demontration on this video, I will definitely make a couple of them, test them and familiarize with the usage an the results.
I think that a quick test for brightness could be using the Power probe to comprare the bulb in the circuit and then in the tip of the energized power probe, if for some reason you do not have the dvom on hand.
Thank you for your videos.
Thanks for the support and views Juan. It’s not to expensive to make your own test light and definitely something I think every technician should have in their toolbox
Great video. Its made me wanna go test the pp4 and do some ohms law .... awesome!!!
DefinitiveDiagnosis haha do it!
It's so nice when you are able to do videos when you have time...that is not under the gun so to speak...lol.
Great video, some great tips here for us all to keep in mind, and good information to know about these various diagnostic tools. Gotta have known good load testing as a part of our diagnostic TESTING for sure. I learned ALOT today from this, thank you man!!!
Voltage drop testing after a test light test is a MUST!
Great video as always Cody! Have a wonderful day and kill it today brother!
PAULY'S AUTO thanks Pauly! Appreciate the support. I see to many guys not loading a circuit. Simple test once you understand it but easily forgot about lol
Another good video. Glad you covered both the PP and the Load Pro, even if you were showing the Snappy version. Both tools have their advantages and limitations, in spite of anything said for or against either. I have both and understand how and when to use them.
I never consider a fuse checked until it has been removed and visually inspected, including the terminals in the fuse block. Simply probing the back of the fuse with a test light is a rookie technique, about as valid as calling a relay good because it clicks. I can’t count the number of times I’ve helped an “experienced” tech with an electrical problem that has sent them down a rabbit hole and has turned out to be something as simple as a burned fuse terminal.
Paul E thank you! Your absolutely right about needing to pull fuse or even Check the box itself. Definitely need to remove the fuse and check it also. Pp is a great tool if used properly. Seen to many times it not used correctly and that’s unfortunate. Not to mention the modules I’ve seen smoked from someone not knowing 🤦♂️😂
Cody’s Auto diagnostics, not mashing that power button requires a lot of self control!
Great video cody I have been using bulbs for a good 8 years it's the best way. Power probe I use only for a ground
That’s awesome and love hearing guys building their own test lights!!
What we need is a variable load tester with a fixed visual indicator for a binary decision pass or fail. When testing a 5 amp fused circuit then dial up a 5 amp load... if the light comes on then the wires can support 5 amps. Want to test a 25 amp circuit, dial up a 25 amp load etc. Perhaps a test light with high wattage resistors and a multi contact rotary switch on the end. The switch will dial in a combination of resistors depending on the desired amperage draw. Would also make a great hand warmer in the winter🙂
Absolutely 💯 percent we need a tool like this!!! I’ve wanted to make one for years with a bunch of Incandescent bulbs with switches to turn them on and off to add load, but I can’t seem to figure out how to make one that’s not super huge and takes up a lot of space.
Great video .
Doug Wilson thank you Doug!
Keith made a video where the pp gave a good connection, but once he touched it with test light, bad.
Sullivan is smart, very energetic too
Great video and demonstration. But I think it's really funny how most professionals don't care for the LP for a lot of the reasons you stated which is a fair point. But the tool clearly works as advertised. Anyway nice to see a fair evaluation instead of the brand bashing.
Johnny M thank you and yes the tool works. It’s just awkward to use. Could be better
And Dan always takes a few seconds in all of his videos to cry about how nobody believed in his tool. It's too bad because he does have good content.
Very good job

Brad85 yes snappy is a multi probe lol. Thanks for watching like always Brad!
more Make a Tool Challenge, this video are awesome
Marko Markovic thank you!
Just an idea for the teslite, what if you were to add leads to it to make it easier to get in connectors, etc. I had a loadpro, it broke so I binned it. I agree it's a great idea just not well executed. I'll definitely be stealing your idea with the banana connectors.
I also will use a amp clamp on circuits to see if I should look into them further. A good rule of thumb I go by is what ever the fuse rating is for that circuit, I'll look for 1/2 of that while operating. If it's well below or above that there is probably an issue. Great content by the way, subbed!
I was definitely going to see about adding some quick connectors on the load pro so I’ll use it more then I do now. Using amps is definitely a good way to see everything that’s going on in the circuit. That’s my go to method for sure.
I surprised how accurate the loadpro actually was, even with it's small internal load (20 ohms I believe) I like your idea for heavier circuits.
Bart Young I was surprised as well. The idea of the tool is awesome. I just hate the tips on it 🤦♂️
i believe the newer version of the Load Pro have an internal 25 Ohm resistor in it. However, after watching your video Ohms Law says your yellow testilight (spelling?) had to have a 100 ohm resistor in it. When you selected 10 ohms, the voltage dropped approximately 10 % to 11.2V. So 90% dropped across testilight, which means your yellow banana looking thing must be 100 ohms.
@@matthewbrice737 Your correct Matthew. The testlite is 100 ohms and the newer version load pro is 25 ohms. To verify all you have to do is put your Meter on ohms and push the button. It will tell you the resistance value.
Great video I really like the stackable banana jacks I'm going to order some on Amazon today. Could you do more videos on using your scope and tips you use.

The power probe manufacturer's should take a second look at this.
Power probe 4 in the feed mode loads the circuit . You can read battery power vs the circuit point you are testing and also read the resistance at the same time on one screen ( no button to push)
Alan Gaudry yes it does and one great thing about the 4. It’s to bad not all the pp have that function
I have the overpriced snap on version (made by power probe) of the hook and I too have run into situations where it told me the circuit was no good "check connection" using the hot shot function (one of the reasons i brought it ohh and the amperage measuring ability was what sold me on it) but that was not the case! luckily experience told me to double check the circuit with a tail lamp bulb. lol.. I still trust if for the most part, but if it tells me i have a bad connection I always double check it now.
Auto Fix Pal yes exactly!! That was my issues as well. I bought this just for that test and it’s very sensitive and sent me down a rabbit hole.
Excellent video sir, I appreciate the knowledge you are dropping. Also, where do you get that sheathing?
Thank you buddy! I grabbed all the sheathing from amazon
Love you load pro probs a awkward sometimes but I work more industrial equipment
I have a handHeld Spot Light. A Big Philips Bulb in a casing With a Handle. I removed the Switch. It Draws 9.5 amps That's My Getto Circuit tester That wont Melt stuff. Best The light was givin to me
That’s awesome man. I need to definitely add something to mine so they won’t melt stuff too
Slightly similar, situation. The ed 18 battery testers, made by miditronics ate faulty due to software/hardware limitations. Js
A little late on this one but Great video Cody 👍🏼. I like your idea using the banana connectors on your test light...Are you making the pulse sensors? If so how can I get a hold on one. Happy fathers Day 👍🏼
Burt Pilon hi buddy yes I’m making the pulse sensors, you can email me at codysautodiagnostics@gmail.com and put “pulse sensor” in the subject box.
The key is to know the limitations of your test equipment and to test your test equipment. I bought a Voltage Drop Pro that will do voltage drop testing by providing a 0-20 amp load. Connected it directly to 3 separate fully charged Optimax batteries but removed the surface load for accurate results. With a 14A setting and 12.7 B+ voltage the Voltage Drop Pro showed 10.9V and a voltage drop of 1.8 volts connected directly to the top posts of each battery...First Fail. Tested the leads and they were good and also swapped with other good leads same result...battery was still 12.7 during the test so how was there a voltage drop. AESWave called vendor and their answers were incorrect and we supplied additional testing but this time on a headlight circuit on my SS. Tested headlamp amperage draw with amp clamp and was 5.1A Voltage drop at LH H/L "On" was 320mV. Voltage Drop Pro testing results with 5A load set the Voltage Drop Pro showed .1G and B+ was 1.5V voltage drop a significant difference and have you chasing a ghost. Others had similar results and the Voltage Drop Pro is being discontinued. I'll be swapping it for a resistance decade box. Key is take nothing for granted and test your equipment and have multiple was to do loaded circuit testing and sometimes having different amperage light bulbs is better than a more expensive method but voltage drop testing on a loaded circuit with amperage draw will keep you from getting slid. Nice video Cory!
Hayward's Automotive I 💯 agree with you having multiple test equipment and test lights. I have multiple dvom (which I use rarely) pulled one out to check ohms and got readings all over the place and and giving false readings. Wild have misdiagnosed the vehicle if I hadn’t caught the reading before even hooking to solenoid. Just got rebuilt to 😒
I have a Power Probe 3 in the only thing I ever used it for was Bench testing
John Bartholomew that’s a good use for it!
6 clicks on the snapback?.. Dayum you have a small peanut.. lol.. just playing.. great video my friend
😂
you have to stress the point that test lights are better for loading a circuit, BUT it has to be an incandescent test light not an LED test light. I know you know that but i dont remember if you mentioned that part in the video.
Your right and I didn’t mention that, good point, thanks
Great video Cody, very concise and well put together. Now I can just show that to my coworkers and stop arguing with them all the time.
I had one question for you. I've been watching the L1 vids, your vids, trained by techs, SD and others... You guys all have a power probe but all say not to trust it.
What is a power probe good for?
Thank you!
Power probe definitely has its place and its good for applying power or ground to a component to test but where guys trip up is checking for proper voltage to a component by checking it with the tip voltage. The tip voltage isn’t loading a circuit and that’s the downfall of the pp
@@codysautodiagnosticsprogra8706 Ok, I hear ya. Thank you for taking the time to reply to all of my questions. It's truly appreciated.
Measure voltage drop on the circuit loaded. The light bulb test on a input for some PWM could result in pcm failure.
dave oneal yes you’re correct. The bulb shouldn’t be used on every circuit like pwm for example
@@codysautodiagnosticsprogra8706Great video keep up the good work.
I don’t trust the power probe for load checking either but it possibly could be a fail in this instance seeing as how a decade box isn’t used for or ideal for passing much current through. Those resistances I doubt are very accurate with any kind of current applied. I put those same banana jacks on all of my homemade test lights and even my otc test light. I hate those cheap clips they come with plus it gives you many more options to connect to. Makes it easy to use the aeswave test terminal kit with it too.
John Pilgrim your right those boxes shouldn’t have much current going threw it and I was pushing the envelope.
I was thinking pretty much the same thing. I know the snapon and power probe both failed the hotshot test on the resistance box but I wonder how much current that box can actually pass. I'm not here to criticize, but that might not have been a great test method. I usually double check by using a 3157 bulb to load the circuit. Great video,btw.
You should always verify a result more than once and by a different method, whenever the repair cost is high or it isn’t a simple fix. I think it’s crazy to not verify multiple times these tools are not perfect as it’s impossible to consider every situation it may encounter. Great video a few others have made videos like this. Have you tried the load pro?
I agree 💯 with you. Yes I was also using the load pro in this video.
Cody’s Auto Diagnostics I watched and noticed you did I think Daniel is a very smart man we can all learn by listening to videos like this very informative. I have been sent down the wrong road before because the new part was defective but that never happens right
He is a very knowledgeable guy and I’ve learned a lot from him threw the years.
Do you think that bulb is enough resistance for checking pwr. And ground on a 98 Chevy Silverado fuel pump connector. I just have a basic multimeter. Not quite sure of the hookup procedure. Appreciate it if someone would chime in 👍🏽
Most incandescent test lights will be enough to verify power with module plugged in and back probed.
What about the load pro. What do think about that tool. I like it myself. But some don’t. Every tool has its good and bad. It just boils down to the tech I believe. Like our beautiful heat here in Phoenix Az. It affects lots electronics like in our garbage trucks here in the city. So maybe that’s why I like the load pro. Great video though
Manuel Lamas I have the load pro and yes it’s a good too imo, only issue I have with the tool is how awkward it is with the leads, there should be banana jacks on it so you can add different terminals in the tool so it’s easier to use. Just my opinion but great idea behind it.
Cody’s Auto Diagnostics I agree the leads are bulky. And yeah you are a 💯 right. Banana jacks would be awesome so you can use the aeswave advanced terminal kit. I just bought an 18 pc snap on testing terminal kit. 190.00 for the price I should’ve bought another aeswave kit. Keep up the great videos.
Manuel Lamas absolutely love my aeswave kit but I’ve also used the Snap-on kit and both kits are nice. Not sure how I lived without the kit for so long 😂
Cody’s Auto Diagnostics right.
same problem lot of techs have with using a logic probe an a test light that they think are the same
I was once that tech tell I got burned lol.
I think the load pro would be better if there was a more normal lead some times I wish I had couple more hands
John Gibson thats my biggest issue with that tool
Please show a simple schematic of your circuit under test as connected to your test equipment as you proceed thru your testing processes.
This has become more of an issue because of all electronic and all of the complicated circuits and components.
Cody do you make them to sell?
No sir I don’t.
Bahaha I don't trust power probes ever. First time I used it on a 2012 Ram 5 years ago to check power to factory trailer brake controller. It showed 12 v. Test light wouldn't light. The wire was rubbed thru above fender liner. I haven't used it since that day. Give me my amp clamp and 5 amp bulb any day

Doesn’t the fact that the decade box started smoking even before you added resistance show that the power probe was right? It COULDN’T handle working current and the hot shot showed it. Also, if you do a voltage drop on a non working component, and you see power and ground, if the component still isn’t working then the component is bad. Period. Yes there also may be bad wiring, but if a component has power at its input and it’s not working, then it’s bad. I always probe the power side of the component with my PP and if it shows voltage, I will still bump the positive switch and see if it works, then do the same on the ground. If the component starts working, I know it was a wiring issue. It’s much faster to properly test a circuit with a PP than all the homemade gadgets and adding lights with different amperages yadda yadda. Great video!
Che Kelley I like your comment about still supplying power and ground just to verify with the power probe. That is definitely a quicker test and only needing one tool. Just an FYI I had a brand new decade box that wasn’t “burnt” and got the same results with the power probe.
@Che Kelley You make a solid point sir, I do the same thing with my Power Probe. That being said I like to substitute a load also just to be totally sure I cover my bases. I think the decade box was smoking because they aren't designed to carry large amounts of current. I know the one I have says something like 300mA max input.
Gearhead Automotive L.L.C. Lol mine has a rating as well and I far surpassed that. It was a cheaper box so I wasn’t as concerned about it and wanted to give an example of how the pp can be misleading. Basically it’s for the guys thinking testing power or ground with tip voltage is sufficient. It’s bad when you see guys that have been in the field for 30+ years and disconnect a component to check power with pp tip. Honestly before I knew better this was how I did it as well. Now I know better lol.
@@codysautodiagnosticsprogra8706 Makes sense brother. I figured something along those lines. You're right about how common that is. Saw guys do it all the time when I worked for somebody else. Same applies for people that use ohmmeters a lot. There are occasions where they can be useful but for the most part it can lead you down a rabbit hole. I was fortunate enough to have good instructors in the automotive program I went through. One in particular taught us that if the ohmmeter says something is bad you can believe it is, but if it says it's good it may still be bad. He was big on voltage drop testing as opposed to using the ohmmeter. There are occasions where it makes sense of course but nothing like some of those factory flow charts would lead you to believe.
Gearhead Automotive L.L.C. Flow charts 🤦♂️ I bypass like six steps of those things because of the dumb ohm checks.
I'm still in the 1st couple minutes. See where this goes...
Some EXCELLENT points made. It reminds me of the people who simply use the DVMM to check powers & grounds... if there's no load or current running through the circuit, it CAN'T be accurate. Still wide awake by the way!! lol ;)
I have my own style of loading a circuit. I made a project box with bulb sockets installed and it's able to have leads plugged into it. By adding or subtracting bulbs in the sockets, I increase or decrease the load. I have the amps written on the box at each socket, so I don't need to calculate what I'm putting on a circuit. Some great ideas, thoughts, and explanations in this video. Really good. Gotten better overnight, with content and execution.
Thank you Cuba! That box you made sounds pretty awesome and sounds like my kind of tool! Thanks for watching!

You must not have seen any other videos of mine. I’ve been building my own test lights for years but thanks for the reminder
@@codysautodiagnosticsprogra8706The comment is for other viewers. They're the ones looking for guidance and know-how.
I would say then don't use it if you like another way.
you should of had live volts not just sound ... because the probe just sees power does not know what voltage your testing for it is just telling you its power like 5 volt ref or 7 volt ref. you just hear sound for power ... thats not the way to test
It makes the noise when the pp doesn’t see a voltage drop, so when the source voltage is the same as the battery voltage. The fact the noise is sounding with resistance in the box is showing how the tool is not seeing it the resistance. I see to many technicians thinking checking a circuit with tip voltage is probably testing the circuit, this is the point of the video.
Im not a fan of power probes. Js
Power Probe is the most overrated tool ever. A multimeter, multiple different resistance test lights and a fused jumper wire is what you need
