Blowing Ignition Fuses!!!!
Just finished putting a rebuilt 4L60E Transmission into my 99 Suburban double checked everything jumpped in turned the key and nothing!!!!Found a blown fuse at IGN A 40 changed it out and it blew again. checke dthe starter and no cracked wires blew it again.
The running lights come on and the dash lights up no problem with a new fuse. Raido, fan, all dash light work when a new fuse is put in. Turn the key to START and the fuse blows. running lights go off but everything else is fine.

Are you sure it's the starter and not some trans fluid leaking out?
That starter shouldn't have any power to it once the engine starts.

yes, the smoke was coming out of the small tube at the rear of the starter and it was also very hot to the touch, I had to wait 20 minutes before I could handle it. There was some smoke from the pipes as it burned off the trans fluid that was on my hands during the install, but this was a starter issue.
The cog on the starter is able to slip up and down the shaft freely and once I took it of and rested it on the frame, I had a buddy turn the keyi was underneath and saw that it had power when the key turned (clicking). I gave it a light tap with a shifter and as I did it sparked where it was touching the frame! after that it seems there is no power there, no sparks and no clicking

Is it possible the starter wasnt aligned correctly on the flywheel causing it to hang up and forcing it to keep spinning with the engine which heated it up?

That is what i was thinking but is that even possible to do?
I believe this is the problem i am now having. Should this turn out to be the situation, what will have happened to the wires conecting to the starter? I havent blown a fuse (very hard to buy the big ones here) but could the wire harness be toast or will the cook up be contained to the starter?

If the starter has no power to it from the wiring it should isolate the damage to just the starter.
