If you can check for power to the coils, the next thing you need to check for is pulse to the coils. I can't picture the bike's wiring in my head so I may be of no help. A coil needs power at all times (when starting/ or running), on the other side you need a pulse/ or "point break" to get a spark. If you have no pulse then you need to get a book and check some specs. Most books offer resistance specs. you will need an ohm meter to read them. I would first double check and make sure you have no spark. I have a neighbor who parked his 1980-something maxum for 1 year, and then ran it for a couple minutes and it died. To make a long story short, he was checking for spark on a silver painted bolt. <---- just a thought. bjawes
