Alternator question
I brought my truck to Autozone to have them check the alternator and battery. Battery checked out fine. They check the alternator by amps and not volts. Said it was putting out 34 amps on a 100 amp alt. Said I need a new one. Took it off, went to Napa to buy one and he checked it out and said it is putting out about 14 volts, and it is fine. Who do I believe. I'd rather not spend $150 unless I know for sure what the problem is.
P.S.- when I hit the buttons for the plow when going down the road, the truck really loses power.

If NAPA isn't checking amps under load he's doing a BS check. The alternator can give correct voltage a low amps and will slowly drain your battery.
Joe is absolutly right about the OEM rebuilds!
