I have a 96 polaris 425 magnum 4x4. I traded for it without knowing a whole lot about it. It was wrecked hard enough to take the radiator out. They replaced the radiator, rode for roughly 5-10 minutes and it died. They never got it to run again. I started off with no spark. Stator wouldn't test out, it had a bad bobbin. Bought new stator no change. New coil, wire, boot, plug, no change. New CDI, regulator things started changing. I don't know if wiggling wires, just changing parts, I really don't know. At times I have a 4th of july spark, at others maybe half spark, and sometimes no spark. It's ran for 5 minutes, and just dies. 15 minutes maybe and dies. It has run up to 30 minutes at a fast idle and dies. But when it dies, its done. The next day it might run, maybe not. It seems to change whenever you mess with it. Does anyone have any ideas what it could be. I would love to ride it, but it would leave me sitting or walking. I've traced wires until I can't see straight. Checked connections looking for corrosion, loose connections, broken wires. I don't know where to go with it now. Any help would greatly be appreciated.
