Testing Motorcycle Battery, Stator & Coil

This week I'm taking you through the basics of how to test your motorcycle's most important electrical components using a Multimeter (aka Voltmeter).

In this video I'll show you how to test your Battery, your Ignition Coil, and your Stator.

These three simple tests can save you a world of headache this riding season and can be the difference between catching an issue before the season starts vs being stuck on the side of the road asking when a part can be delivered.

Fantastic video, well explained for the novice to follow and clear instructions on how to use a multi meter. Thanks!!!!

[chriswiggins]

I just discovered the low life podcast today and heard you mention the YouTube channel. Awesome stuff man!

[davidknowles]

Cheers mate so easy i think even id have a clue, I've just bought a multimeter and replaced the battery, im getting a reading of about 14 at 3000 rpm. Im abit wiser after watching your video and atleast I've got abit more clue how to use the multimeter.

This is a huge help man. Thanks for making this video.

When is the last time you checked these systems on your bike?

[tommymartin]

😊thank you very much for showing me how to test my stator

[badmatt]

2:50 my HD coil has 4 input pins. How do I test this?
Output, you said needs 10, 000 ohms.
My meter shows 6 k ohms.

WoW! What a grrreat Video! Thanks for sharing.

Also if You could at sometime show the Lever Start for these 4 Speed's.
Have everything to put a Starter on My Bike now.
Bought the Lever but can't find anything on video putting in on.
Thanks again

Great no shit just good video easy to understand thanks👌

Hello should you ever see any continuity between primary and secondary side. Or they should be always separate.. and if you do see continuity on your meter does it mean the coil is bad

[MoeLarrycurly]

You may have a video how to test the four wire 4 pin stator for a 1970 Harley-Davidson big twin or could you direct me to where I could find good information how to test it Thank you

[benpaynter]

Hey man my 2008 rocker has a different ignition coil would you mind showing me how to test that one please or a brief explanation on which pins I test on and what readings I should get? Would appreciate it hey!

[ragz]

Thanks again Grease for this video. Used it last weekend to confirm I had a fried coil. Then, was able to pass knowledge on when getting a set from my buddy and showed him how to test coils. 🎉

Okay this is a great video but how do I test the out put of my stator or the voltage regulator itself?

[technokids]

Yo Grease! I'm currently diagnosing an electrical problem and need to test my coil. I have a cycle standard (CHROME 12V SQUARE COIL 1948-60 HARLEY-DAVIDSON BIG TWINS). How would i test this coil? I run my multimeter across the top holes where spark plug wires come out of and get a reading of around 17K ohms. When i touch the side terminals on coil I get NO reading as in no ohms on any of the settings. Im assuming this means I have a bad coil?

[ragz]

Surprised you didn't mention grabbing your multi-meter on tha cheap from HF. Gotta deep dive into old LowLife podcasts for that! 😉

I can’t find the stator on my bike, I have 73-74 xlch sportster and mine doesn’t have a plug that pops out. The regulator has two wires that hook up to the generator and then the housing for the generator is connected to the engine

I have a 2001 kawasaki vulcan vn800a I tested the battery with the bike off and had it in the 13.5 and when I had the bike running it was 15.1 + when reving does that mean my big is charging?
