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. Any suggestions???
