Swapped alternators and now the car won’t start and is shorting out

[Yuri]

Hey guys, just changed out my alternator and now my car won’t start. I just get a loud click and everything dies. No dash lights no nothing. There are only 2 wires so not sure how anything could be messed up. Just going out to check the wires again now. Any words of wisdom would be very helpful. It is a used alternator, but not sure how that could just short everything. Sent from my iPhone using Tapatalk

I unplugged the small cable on the alternator and the car now turns over, but the batter was severely drained. Had to charge it overnight. No experience with stuff like this but I’ll keep you guys posted. Also any info on this wire would be helpful. Sent from my iPhone using Tapatalk
