I bought a rebuilt alternator a while back and just dropped it into my '87 FJ60. My old alternator was pretty old, but working... with recent down time I figured I would drop the new one in. CHARGE light came on inside the truck after installation. Voltage on the dash gauge was low. I put the old alternator back in and the light went off, voltage back up.
After all of that I noticed that my new, rebuilt alternator did not have this small connecting wire with the rubber cap on the back of the alternator (see pic stolen from the web). I'm going to take that wire off the old one and put it on the new one, hoping that was the issue. Just wondering what that wire is for. I assume it's necessary and hopefully the cause of my issue.
Thanks for any advice.
