Couple people have asked why I tested it if it didn't produce spark when the "kill-wire' was disconnected. This video is just a guide on how to test your coils (get the proper specs and use a multimeter to test for resistance). Basically, if you unplug your ground wire on your coil and it doesn't produce spark, simply replace the coil. However, if the coil produces weak spark, then you can use this video as a guide to test your coil, and determine if the coil is the issue. I also have a video that shows a coil producing weak spark, due to a spark plug cap that has too much resistance. Once the engine got hot, it would shut down. Watch that video here; kzread.info/dash/bejne/l551uph7npe9g9I.html

Have you ever run across a coil that tested good and would fire until the engine got hot then shut down and stop firing?

@EliminatorPerformance

5 жыл бұрын

Yes, usually due to excess of grass/dirt build up around the engine and coil pack. This insulates the engine an causes the coil to stop working, I've seen it happen from mouse nests too!

Could also been a plugged fuel cap as well that's shutting your Engine down after a while. It could be vapour lock, because the cap doesn't let air into the tank so it stops fuel from going into the carburetor. Once you let it sit for a bit they usually fire back up and run for about 10-15mins.

I watched your video, checked my coil and found out it was a ground issue. Without your help, I would of ordered a new coil when I didn't need it. I do appreciate your video..

It really amazes me that backyard mechanics still don't know how to use a voltmeter. I have a very close friend he's very good at fixing things but you give him a voltmeter you would have thought you just asked him to cure cancer. After buying my first one back in the '80s I had good friends of mine that were mechanics and they showed me how to use it. I also fortunate that has a brother-in-law who's a electrician and he had showed me things that my mechanic friends did not know. Now you go to today I have voltmeters all over my house. Every time for the longest if I saw a good deal on one that did something different than the ones I had I went right out and picked it up. I enjoyed watching you diagnose these coils. I have watched several of your videos and enjoyed them all.

Excellent! I wish more KZreadrs would be as concise and to the point as you are. I just subscribed. :) A note: It appears that some of the aftermarket coils, and in fact the coils on my John Deere (Kawasaki) mower have the kill switch terminal connected internally to the primary, rather than the secondary. This results in an Open Loop (infinite resistance, or 0.L. on the meter screen)... yet the coil is good. Grounding the primary or the secondary will kill the spark, so either side can be used by the manufacturer. If the secondary is connected to the kill terminal, you'll get the same reading you get when you read from the plug wire to frame ground. The plug wire will have no, or very low resistance when you check ohms to the kill terminal. But again, if they made the coil such that the kill lug grounds the primary, there will be no connection at all (open loop) to the frame or the plug wire. Normally only one coil fails and the Right coil was obviously bad. So... it's possible that these coils had primary connected kill switches, and the Left one was okay. B to C or B to A should be totally open on a primary kill switch lug... they're making these things both ways... It's best to change both of them anyway, so it's good the customer got a fresh set of coils. :)

At least Kawasaki is very good about giving you full specs on everything in their service manuals, including resistance readings on all relevant electrical components. Onan was also good about giving good specs in the service manual too. Tecumseh was probably the worst about giving you all the needed info.

Great diagnosis. It’s always a good idea to test the meter and leads before testing the component first though. By just touching the leads together first you should get 0 ohms. Just in case you have selected the wrong range or have a faulty lead on the meter or have one of the leads plugged into the wrong socket of the meter.

Well done. No chatter. Right to the point. I was wondering if the tolerance is pretty much standard for engines of a certain hp. If they are, you don't have to look around for the manual every time you're working, say,on a Briggs 17 to 24 hp. For example, if you're setting valve gaps, after a while you realize that if. you're dealing with an ordinary engine type, you don't have to look up the settings every time. You sort of know.

When measuring the coil off an engine that dies when it warms up, I use a heat gun to see if things change as the coil gets hot. I have found a number of coils on mowers, chainsaws and weedeaters that will open up after they warm up. When in doubt, replace the coil. They are responsible for many intermittent problems after a few years of operation.

I have the same engine Kawasaki in a Husqvarna tractor mower. My first diagnosis was no spark. But I was wrong. I took a test light n placed it in spark plug cap and other end on spark plug(still in engine). Turned over engine and when I looked at plug there was a spark while holding it close to plug. Then with engine switched on I heard a small noise( sizzle). Realized sound was coming from bottom of carbaretor. Then cleaned plug in on solenoid. Still heard noise. Then tapped it gently with screwdriver and heard a click. Engine cranked up. I cut grass with mower for an hour. No issues. Just be sure there is actually no spark b4 buying a coil. I have been told they rarely go bad in pairs. Usually just one goes bad. Great video but I’m certainly a novice on a volt meter. Both mine checked bad but obviously my skills are not where they should be on the volt meter.

Great video - thanks.

My ride-on has the same FH531V v-twin. It still runs but it's been progressively running rougher on each use and I found the spark is intermittent on both plugs. What would you know, it's got the same issue where both ignition coils are out of spec! I've used the mower every single year since purchase and so it would seem they've just gone bad with age.

Thanks for video keep people from getting rip off

Replaced coil, still no spark. I am thinking I probably should have ordered a condenser also. By the way only way for me to find parts is EBay, straight from China of course so just hoping they are good. Anyway in Checking the condenser, I am on 20k ohm setting, Red probe to wire, black too body, meter just stays at 1, should I not see a certain ohm reading meaning i am charging the condenser? Then I would check DC volts, mv I would think? Or do I just want it too hold a charge? Thanks for any help.

can you have spark and still have a coil issue? I have Fc540v kawasaki that died but throws spark but will not start and blows flames out carb. key isn’t sheared and magnet hits last part of coil at tdc. all i’ve got left is the coil or valves messed up but I did check valve lash and it’s fine .006. Tried replacing the ignition module aka ignitor and still won’t start. my coil test says plug end to base is within specs at 11,300 but kill to base I can’t figure a reading based on specs calling for 60-100 and the best i can get is 0.7 on the 200 ohm setting. I tried pulling what you called kill wire that goes to the ignition module but then I have no spark at all.
