2002 F450 7.3 Turbo

Ok first problem

Starter Motor fuse kept blowing and I spent weeks trying to figure it out. No luck. so wired up a push button just to get the truck started, its a work truck so it was needed asap.

2nd problem

the truck stopped starting completely. Wont start in Park or neutral and after a NEW STARTER (because I thought the solenoid on the starter was bad I replaced it) Everything work correctly for one start with the key. after the second time trying to start it blew the starter fuse again. So i tried the straight wiring to starter. still nothing. I was wondering if there are any shims or anything at the transmission housing to correctly position the starter. Im thinking that maybe the gear is stuck or gets stuck sometimes. when I straight wire the starter it does nothing but the wire gets hot so I know its pulling.

Please help.

 

If it is not even turning the truck over sounds like a ground problem, check the negative cables at both batteries and the block, make sure no corrosion and there is a good connection.

You have a short to ground on the trigger wire. Did you disconnect it from the starter when you jumped it? I would look first at along the side of the oil pan.

 

Thanks for the help. It turns out the starter wire had been rubbing on the frame and finally started shorting out. Repaired the wire and everything is good!
