Somewhat off subject, but rebuilt alternators often can be junk. Just because it was old, I replaced a perfectly good but 190K mile alternator on a Chevy Van I use to tow my racecar with a rebuilt - the rebuilt died (bearing failure) in less than 10K miles, and I had to reinstall the 190K one in the middle of the night on the road.

Rebuilders often just replace enough stuff so it works, everything else not absolutely needed is still the original old stuff.
