It sounds like a possible grounding issue, I would check you wiring goiing to your starter, also from your main 40amp fuse box, and of coarse your battery cables.

Agreed. Something has shorted to ground, something that carries a lot of amperage in normal use, like the cables as Michael said....evidence in the starter engaging by it's self


Sounds like your starter solenoid is stuck closed, you may have to replace your starter assembly, and that may also be causing you main fuse to blow.

ignition switch is shorting out and blowing the 40 amp fuse immediately when key is turned on... replaced ignition switch problem solved..shop cost is 153.00 for switch...
