1.I removed the old alternator and found that it had a rear bearing issue that didn't look good at all. If you look closely at the alternator on the right, you can see there are only a few roller balls left in that bearing. I'm not sure how much longer it would have lasted, but for once I got lucky and inadvertently found the issue before it left me stranded. The new alternator from Powermaster needed to be clocked so it would mount properly in my truck. See how the plugs are in different positions compared to the mounting tabs?
