My truck seems to have an alternator problem. When hot, the voltage will drop to 12.5 sometimes and stay there, then for no reason, jump back to 13.7-14. Engine revs or electrical load does not seem to matter. It has every electrical accessory available with a 160 amp alternator. The battery is relatively new also. The voltage drop is slow, not sudden, as is the rise. I have checked every connection I can find, to the point of checking terminal grip. I was an ASE Master tech before closing my shop a few years ago, and would have sold a customer an alternator already. I am on disability now, and $275.00 is a big chunk of money. Do you have any ideas of something I might have missed?
have the same problem?
