Iv watched tons of videos trying to learn about coils on older outboards.. none come close to this video! Well explained with so much information. You just taught me so much. Cant thank you enough!
Of all the Videos on CZcams, yours was the best explanation of how to test a coil!
Awesome detail. As a newbie, I was able to confirm a new coil had no spark. Thanks for the video.
You talk about a really nice gentleman I was gonna leave a message on his phone to call me back on Monday but he picked up Sunday evening gave me what I needed to know and I deeply appreciate him and his content thank you so much TMike
Thanks so much for the very clear instructions you give. Looking forward to watching all your videos.
Love your demonstration and best instructor you can ask for
I have the fluke 77 with Roman numerals behind it the three sign my brother had it for years he passed away in 2001 great videos I love the vintage Outbord motors 👍🏻
Great job! Thanks for the patient detailed step by step video. Keeping it cool, with one great video at a time.
Amazing job explaining this thanks T-Mike
Hi Mike, working on an old Elgin 2hp motor and finally got it running today. found the coil was cracked but it worked. seal it up. tried to start but still no spark? turned out the flywheel magnets had just enough rust on them, and the coil contact it wouldn't run so hit them with some sandpaper and got spark. moved on but the carb was clogged up. took it apart, cleaned and ran wire through all the holes. Fired right up and ran well. Love it when I can get these old motors to run.
Very instructive video. Very clear and relaxing. Thank you. Vincent from France.
T Mike great explanation of how a coil works. Thanks..
Very well done!! You are an excellent teacher. Thank you.
Thanks for these great videos. I’m from south of Lafayette. I ever get out to your neck of the woods, I owe you a beer for all your help sir.
Great tutorial!! Thanks again T Mike.
I’ve learned a lot u explain in way I understand thank u
Much obliged for this video.
Thanks Mike don’t know a lot, however enjoyed.
Welcome back home : ! lazy cajun.. hope you had a good repose ~.. now lets get back to work !! ;
Excellent informative video.
Nice job yaaa.u da man.
If you have a merctronic coil tester you can test full spark range from low to high to detect breakdown
Thanks.
Merci beaucoups.
@michaeljsimon great video. Minute 3:44 OL shouldn’t that be Open Leads? Just checking
Wow !😊
good vdo.
Is there a way to get to the primary circuit of the coil while the engine is running for rpm tests with multimeter leads? I know I can do it with an inductive pickup on the spark plug wires but I don't have an IP as of now.
I tested the resistance on the coils on a 1971 9.5 Evinrude, because no spark on top cylinder. Both secondary coils (to plug attachment) tested at about 4000 ohms so good. The primary coil (for top cylinder) reads 0.3 ohms, the other coil read 0.7 ohms. Since these are less than the 1-3 ohm range, does that mean that the coils are bad?
On my evinrude 25 hp 1976 model NO. 25R76E. testing whit multimeter the Driver Coil" located under the flywheel. is 1.9 homs.
When i rotate the flywheel Setting the points, i conect the the Driver Coil, and the points is open the multimeter indicate continuiti.
I`m trying to bring this `56 10hp Sport win.. back to life.. ! she kicks over with starting fuel ~ but dies .. i need ur help !! I only listen to YOU ;(.. IM big fan !! AND IVE SHOPPED ON UR SITE .. also have a 7.5 in 3boxes .. you want.. ?

If the coating of the coil if cracked a problem?
Hey, this is exactly the information I am looking for. I’m trying to get my 67 Evinrude 3 horse folder running on both cylinders. These old 3 horse don’t have the inspection hole in the flywheel for adjustments. I don’t have the aluminum pointer for setting the timing. Is there a way to set the timing without special tools?
That red Johnson 7.5 on the back of the Jon boat sure is a “Looker”.
The information I referred to looking for was coil testing. I do need that.
The timing question is separate. Hate to buy a timing pointer to use once. Hope there’s a “close enough” method.
@@kentyler966 set cam to highest position and set points to 2000 using feeler gauges.
Thanks for the information on static timing my 3 horse. When I do the timing do I need to have the throttle closed or wide open. Wide open I believe I has the timing fully advanced.
Thanks again.
Wide open
@@michaeljsimon Hi from across the pond. I suspect my coil on my 5 HP Yamaha 2 stroke outboard. The coil has only one primary input lead. I suspect that the second primary lead is connected to the coil mounting, which is therefore earthed to the alloy shroud around the cylinder. Am I correct ?
Anyway I’m off to check the resistance as you suggest !! Great video.
Hi Mike. Why are my two mid 60's OMC 3 horse are not getting spark They got new ignition parts replaced and ran perfect. I treated the gas and ran them every year for 5 minutes and they would run great. Then I missed a year and they have not started since. Even a little ether failed to get a blip. That tells me it must be the spark. Why does this happen so often with outboards? Would taking the ignition parts apart, cleaning and putting back together fix that? Best ways to prevent this in the future? Thanks.
Try cleaning the points with 1000 grit sandpaper.
T Mike, when putting the ignition coil back in, what is your "trick" to adjusting it so it doesn't rub against the flywheel interior?
Use a screwdriver to align coil with base.
hi t-mike, question for ya, what does it mean if primary has huge fluctuations, sometimes over 100 drops to 40's rarely does it stay 1.7 maybe only once. I noticed it changes drastically when I move the wires even just a tad. Secondary tested fine tho. Do I have a bad coil?
Yes. Going open
T Mike, I have 2 coils from a 1957 35 horse Johnson. The primary's both measure 1.2 ohms. However, the secondaries measure 4,500 and 7,200. Is this a problem and which coil is stronger? They both seem to produce strong spark. Thank you for your time.
Your fine - all good. Just so sparks jumps 1/4” gap
Mike, I really enjoy learning from your videos. I have a 1976 9.9 Evinrude that idles really rough. Went through carb, plugs, and when testing the coil I have 12000 ohms from lead to plug wire. Could that indicate a bad coil?
How are you testing spark ?
Pulled plugs and grounded to engine. I have spark when pulling cord but once engine runs for about 3-5 mins it starts running rough. I checked the ohms and get after shutting it off and get OL.
I added a video on my channel if you want to see/hear it. Rebuilt carb, new plugs, fuel pump. Kind of stumped but after watching some videos and research I’m thinking bad coil

@@latitude42fishing7 watch my videos.
Tip #1 - Spark should jump a 1/4” gap with a good tester.
Tip 2 - Use a timing light to determine spark issues
All this is in my videos.
T-Mike have you ever had a coil work intermittently? My 1995 70 hp Johnson will shut off at WOT sometimes and sometimes I have trouble starting it after it has been running. I had to get towed back to the launch the other day, parked the boat at home, got up the next day and the boat started right up?
Yes the winding of the coils go open when heated up and work fine when cooled.
@@michaeljsimon Thanks for the reply Mike I appreciate it!
I picked up a 1963 Evinrude 5.5hp. The coils test out good but they look to be the original coils. The motor hasn't been used in over 6 years. Would you replace them anyway?
Not necessarily. I change them on full restores but not on repair work.
My new 2 sierra 18-5181 coils on the secondary are 10.2K. Can the coil be 10.2K? The primary winding is normally 1.7 ohms. The motor is a johnson 5hp LdL13E. The motor cuts out when the moment comes. There are two capacitors to replace because they are 0.2uF and they should be about 300uF
Yes 10.2K is possible.
Vintage Mike where do you buy parts i am in montreal quebec Canada
Also where do you buy the water tube O rings and or spec them ?

Thanks!!!! Watched the link.
Great Video
Answered my questions. !
How to test a ignition coil and the test all the ignition palate whit multimeter please

Hi T-Mike, does it matter if I used two coils with different ohms readings....example...4.45 and 4.05 ohms. Thanks.
That will work fine.
Thank you sir!
I'm currently rebuilding a magneto. Your videos helped greatly.
I am trying to find ignition coils for 1955 Scott Atwater. Model number 3355. So far no luck. Is there a way to use a compatible ignition coil and spark plug wires? Thank you...Geaux Cajuns! Geaux Tigers!

I can’t find a ignition coil for the mercury 3.9 sn# 1885451. So you have one?
Sorry. No
czcams.com/video/Sk3IrxYp90E/video.html
“OL” stands for open line. FYI.
Hi I cant find you on ebay? thanks

How do you add a kill switch to older vintage motors. It's a federal law now that they require on all motors 2 horse and above
Wire the kill switch to each side of points. Old motors are grandfathered in not required.
Hey T Mike Can you check your email i need your help.
