leachy 0 #1 Posted March 5, 2018 For some reason my coil has burnt out on my Wheel Horse 518H Onan 2 cylinder unit. I have just bought the unit second hand and its been in a field for a couple of years. There is no start on the key switch so not sure where that is but when powering up the ignition the col burnt out. I cannot see this type of clamp down wasted coil for sale anywhere have they replaced it with something else???. What is the easiest way to wire it up for ignition and starter system?

rmaynard 15,794 #2 Posted March 5, 2018 All sorts of Onan coils, new and used on eBay. Download the manual for your tractor from our files section for wiring help. You might also want to get the proper ignition switch as well. Share this post Link to post Share on other sites

leachy 0 #6 Posted March 26, 2018 Gents How do I change the ignition triggering device on the flywheel. It does not look easy too get at. Also what is the ressitance Ohms reading I should be getting from the triggering device. Does it change as I rotate the engine? Share this post Link to post Share on other sites
WVHillbilly520H 10,376 #7 Posted March 26, 2018 @leachy, You will need to pull the engine tins (flywheel shroud ect) then using a puller such as an automotive harmonic balancer puller to remove the flywheel itself (after loosening the main nut/bolt holding it to the crankshaft) and there it be there are actually 2 parts that SHOULD be changed while you have it apart $ well spent the first time apart and you don't have to pull it apart again the trigger ring and ignition module, Jeff. 1 Share this post Link to post Share on other sites
