When I turn the key to start the truck, the 15 amp ignition fuse blows. The battery will go dead overnight if I leave it connected, even when ignition switch is off. I replaced ignition switch. Same problem. If I jump off the starter solenoid while ignition key is on, the truck will l start right up. Would there be a short in the starter solenoid or the starter relay? Or something else?

So the fuse blows in the"crank" position? Then I would use a meter to test the small wire on the solenoid for continuity to ground. If it blows the 15 amp fuse it is a dead short. Try unhooking the small solenoid wire and see if it still does it. If so it is the wiring between the two, if not it may be the solenoid or starter or the wire from solenoid to starter motor
