I have given up on my old alternator and regulator. After 2 hours in 95 degree heat, I threw in the towel. I have a cs alternator that bolts right in, only needs a small modification on the adjustment arm. So, the mechanical part is done. I have a question on wiring. I understand the 1 wire hook up but this alternator has a plug in on the side with one wire coming out. What does this wire go to? Do I need to hook it up? Still confused but this looks like the way to go in the long run.
