New here and can use some help. Neighbor has a 2000 Rancher ES blows main fuse with key off. Problem started when riding, just died, found blown fuse. Rigged up test light to each side of main fuse spades. The only way the light will go out is to disconnect the dash, rectifier and key switch. What do these three things have in common. Or does he have 3 different problems. Ordered a regulator/rectifier. Will swap this out and keep going. The regulator/rectifier looks damaged near the mounting bolts. Thanks in advance.
