no start after alternator swap
I'm turning to this group as I'm out of ideas as to why my 89 YJ with the 4.2 won't start after I swapped in a high output alternator. I know I have some electrical gremlins, thanks to the previous owner and some rodents, but I drove the Jeep this morning! Getting ready for plowing season, so thought I'd swap in a higher output alternator. Got it in fine, with only one incident. Even though I had disconnected the ground at the battery, I forgot I had a ground from the other negative terminal (marine battery). Touched the positive wire to the alternator while inserting the alternator and got a pretty good spark! Finished the install, and now the Jeep won't turn over. Have 12.5 volts at the battery, lights work fine. Cleaned the negative battery terminal and cable that I had removed and reattached. When I hit the ignition switch I hear, I believe, the solenoid click. I have not tried a jumper down to the starter yet, but it's getting dark and I'm too frustrated to think about this right now. Any ideas from anyone on what I should try next?
