graywolf1939 24 #1 Posted May 6, 2016 Seeing I have the Flywheel off the Wheel Horse 518-H, and in the process of installing a new Ignition Trigger Module, how do you remove and test the Trigger Ring? And what is the Part number ? Thank you in advance guys, Dick Share this post Link to post Share on other sites

entropy 104 #3 Posted May 7, 2016 (edited) http://gravelymanuals.com/pdf/Onan_P216G_P218G_P220G_Parts_Catalog_19981000.pdf this is a good source for part numbers. I would be interested in how you test that piece as well. page 16 of that site above has the part number(166-0767) rotor, ignition. when I was going thru my electrical issues I replaced lots of stuff, the demystification guide really helped, so much so that i printed the entire thing out and have it in my garage wheel horse file box with receipts of all work done. I wonder how you test the stator as well, never did it. Another source I use when trying to get parts for my onan is my local john deere dealer. the WH520HC has the same engine as the John Deere JD420. The parts are a bit pricey but they always come through. Edited May 7, 2016 by entropy 1 Share this post Link to post Share on other sites
