I know this is a common issue. The 89 fourtrax is dying after warming up… can let it rest and will fire right back up. The local power sports guy said it is hardly ever the ign coil (which I don’t believe based on this site). with battery disconnected, I have about 10-11v across the battery terminals, and it drops to 3v when I rev it. neutral light flickers until I rev it and then goest out completely. I figure this should let some experienced guys know whats up right away. suggestions?

Thanks!
