WHX?? 47,017 #2 Posted May 11, 2018 Relax Allis help is on the way. Only one who gets to shout at me is my wife! First off 2nd off did you check the coil and did you download the manuals from here? The book gives you specific trouble shooting steps as well as resistance reading of components. Check all grounds? I can only assume you meant a P220 Onan. What tractor are we working on here ....520 by any chance? Share this post Link to post Share on other sites

WHX?? 47,017 #4 Posted May 11, 2018 Check the nine pin connector, check the fuse folders.. all common 520 problems. Sometimes the fuse holders look good but are intermittent. Sounds like you have an intermittent problem. 1 Share this post Link to post Share on other sites
