Thank you just the info I needed!
Thanks, your'e a sweet guy.Looking to find test method for 2 horse trailer. This.This got me started.Have a festive and interesting Fall, this season.
just bought a trailer few days ago.everything worked on the hook up from truck to trailer except back right turn signal.We tried everything,nothing.We took the back rear tail lights off and spliced a wire to the red (hot) instead.it worked! there's a bad connection in the piggy tail section on the green wire apparently.so the wires all the way from the front of the truck,to the rear tail light (spliced),from there to the harness.from the harness connecting to the harness of the trailer and presto.it works.Had it not been for the guy i bought the trailer from,i would of never bought it,let alone brought it home.he knew his stuff with wiring.
Thanks man, this drove me crazy...I knew my trailer lights were good, same module on my 01 Cherokee went bad. Appreciate the video
Glad it helped
good information on electrical checking on the trailer car hookup. thanks
Hope this helps you out
Thank you. This was exactly the problem I had. I called around and found the replacement converter unit at U-Haul for $50. It took about 1 hour for replacement.
Thanks for watching. Glad this video helped you out.
Thank you. God bless.
Thanks for the info.
Thanks. I understaood everything you said. Not sure what people are talking about.
lol...finally someone I can relate to..lol
I understood you as well.
Helpful video, did not think to check the module.
+Tom Bilyeu the one on my 2004 Jeep Grand Cherokee went bad. I had to replace it.
wicked hard core vid!

If the ground at the hitch really is where most problems happen, I think that's the first thing I'd check, especially if the trailer's hooked up and the truck is idling in the driveway.

Hmmm my break lights/ turn lights are ok but I noticed my night time running lights font work also the amber lights. I don't know what to do
love the accent what a nice young man….
can you tell me the make and model of your tester and where you purchased it. I know nothing about them but have no lights on a trailer to which I just installed new lights and lines and I'm pretty sure they are connected correctly. Also, I just recently rented a trailer at U-Haul and all the lights worked. But who knows, maybe a fuse blew or the connector was damaged. But I don't know if my voltmeter will test this as I think it is set for house electricity. Is your meter for cars only, yes? What is it, please?
Here is a link to the test lights that we have in our Amazon store: amzn.to/3b7Vt7b
Whya. Trayla.😂😂 Thanks for the help.
lol..thanks for checking us out
Yikes!! :( Nice Troubleshooting!
Thanks for watching.Glad this helped you out.
I have an old tent trailer that has black, green, yellow. It also has a blue/red wire alongside. There is also a black/red wire coming out that was screwed into the trailer (potential ground). I cannot get the 4 way connector to work. I've tried almost every color combination. Any ideas? Best I've got was the opposite signal was working and the other both flashed dimly.
If you have test light test the circut
Hey i have new curts trailer harness wire on my car and new trailer light.when i turn my headlight on my trailer light up but no turn signal, hazard light or brake light. Do you think its a bad ground from my car wiring harness?
You may want to test the plug at the car first to make sure all of the signals are working correctly on the individual circuits.
my trailer has lights on the right side no problem. the left side has the turn lights but no break light and park light
You may want to test the circuit with a test light to see where you are loosing power
So we should not check for a bad bulb first?
So, just to make sure I understand: when the truck is running and the lights are on I should get a signal from the ground on the truck? Currently I am getting a signal from the brown, left, and right - not the ground.
The ground will not give you a signal it's there to ground the wiring so that the signals work
Thank you, I was hoping that was the case. It makes sense when you think about it. Anyway, thanks to you the problem is solved - trailer lights are working perfectly. Much appreciated!
No problem at all. Trailer lights can be a pain
My problem. 2006 Town and Country. I check for current and I get 12v at connection prong. When I connect the led lights, voltage drops to 6v. What could be wrong. I retied ground connections screws, unless the lights shorted out?
There’s probably a bad ground in the trailer. Clean the grounds and see if it helps
Yes, it was a bad ground producing only 6v. I appreciated man, thanks!
I'm trying to hook up a four pin connector harness to my car that hooks into the trailer. I think I have all the wires connected properly but there only seems to be juice to the left turn signal on the adaptor...any ideas?
You may want to first test the circuits that you are wiring into to see if there is power in those circuits and that they are also functioning correctly.
@@HomeOwnerRepair thank you. That was two years ago... I eventually figured things out. Thanks again.
I was having a similar problem and was spending way more time than I had planned to sort out the issue before hunting season.. I was ready to hire out to sort out the issue as the lights went from only one side to none at all.. checked truck set up.. redid trailer wire set up and checked ground as well.. hooked truck to another trailer and everything worked! Talked to a pal who suggested I grind down the metal flap from trailer the light is attached to.. sure enough the flap was rusty.. i ground down the rust to bare metal and used dialectric grease .. changed the nut and washer which were rusted as well..tadaaa! Christmas tree lights in September!
When I press the brake and put the test light on the green and yellow wire on the car connector, should the light up? Mine don't light up with the brake pressed but the green and yellow flash when the blinker is turned on
You may want to test them all individually. What type of vehicle do you have
HomeOwnerRepair 2002 Subaru wrx sedan. Towing my jetski trailer only. I now have running lights on both, right brake and turn signal but no brake or turn signal on the left side.
HomeOwnerRepair all wires from car work and are powered off of converter.
If all of the wires from the car are working correctly the issue might be in the trailer plug end or wiring. I would probe the trailer plug wire to see if the current for left side your loosing is beyond the plug on the trailer. I like to use a test light because they are easy to use.
HomeOwnerRepair awesome, I'll give that a shot and see what I come up with
I have power beyond the pigtail connector ,But the turn signals are not flashing for either right or left on the trailor. The break lights work just no signals. What could be causing this issue?
If the circuit flashes on the pigtail, the issue has to be on the trailer somewhere
Thankyou That's what I thought
When I plug in the trailer hitch it blows a fuse in the car (Honda Element 2010). Any suggestions?
Check to see if there is a pinched wire somewhere or a frayed wire that might be grounding out.
How do you get the brake lights to work?
You have to start at the vehicle and make sure there is power to the brake light circuit at the plug end. If there is then the problem is in the trailer wiring.
@@HomeOwnerRepair Alright thank you!
My boat trailer has the same prob but the ground wire is melted? Don't know what the problem is
Something somewhere heated it up. You may want to trace the wires to see if something has been wired incorrectly.
Homeowner Repair yk that was 2 years ago. But thanks for the reply. Actually have purchased a new boat and sold that one. So many problems started popping up we new it was time to get rid of that ole baby. Still miss her tho 😢
Do you know why where you plug in the trailer plug I tested them one of them have more power than other one
I'm not sure what you are asking
@@HomeOwnerRepair so when I do the tester on the plug in the one for the trailer breaks the light not as bright as the other lights
I am having trouble with some of my lights not coming on
You may want to test the outlet on the vehicle with a test light to see if all of the connections are working correctly. Hope this helps you out.
I just bought a trailer i hooked it up only my signals and break light. So i rehooked it to another truck and they all light up and stay on why is that?
You may want to check for a wiring issue on the trailer. Clean the ground connections first
If the trailer stays lit on the second vehicle, your first one has a problem with the wiring or most likely a bad fuse. I had this happen a few years ago and a mechanic replaced one fuse to make a rear turn signal work. I would check the fuses first as they're the easiest to check.

All test lights have poor wire clamps . Clamp the very smallest ViseGrips tightly to a good ground , then the test light ground clamp to them . Keep in mind LED testers will illuminate with very low voltage .
Forgot to mention , do not poke wires with a light tester, never .
Love the accent. What accent? 👌
We're in NH. Thanks for watching.
So they sell them at Walmart ? So just go in an say the make an model / year of your vehicle ??
Usually they are in the automotive section
Tilt Trailers must be grounded on the bed not the tongue! if you ground on the tongue your going through the hinges and the lights will cut out when you drive, if you ground through the bed where the lights are bolted to, your good.
Thanks for the added tip Greg!
Trailer will only light up when headlights are turned on. All bulbs are on but , brake , Left, turn, right turn, emergency flasher, (functions) not working. Light on but not functions work???
Test the plug coming out of the vehicle first to see if all circuits function properly. Then follow the wires on the trailer to see if any are crossed or broke or possibly a bad ground.
Screw the wiring, check your tire valve stems first. I borrowed a trailer from this clown that never checked the valve stems. Valve stems don't have a freakin R in them either
Brian Strange This video might help you out czcams.com/video/jmsZsYuqAl0/video.html
Homeowner Repair:
If the trailer turn signals are also the trailer brake lights, then if I hook the brake output wire to the trailer left and right turn signal wires, doesn't that mean my car brake lights will come on when I use a turn signal, and that my car turn signal lights will come on when I use my brakes? I don't want that to happen, lol.
If the wiring to the trailer is okay it should function correctly.

@ 0:35 Remember What ?
There no "R" on Traila lol
Wiring kits are CHEAP so get off of your tight wallet and buy a NEW kit and install it. Most people waste more money every week on Coffee,Beer,Wine,Cigarettes, or something.
Good point, Thanks for watching!
