Just this minute I picked up my car from a local mechanic with a new alternator.

He charged me $180 for the part and $145 (1.5 hours) for the labor which seemed very reasonable.

I tested it with a volt meter and I am getting a reading of only 13.4V when the car is idling. When I revved the engine to 3,000RPM, I still only got around 13.9V.

I measured the current while the engine was running with one of those clamp style meters and got only 33A running so I don't think there was an excessive draw of amperage (all accessories and lights were off).

Did I just get robbed or is this normal?

It's a rebuilt aftermarket alternator. What are you expecting? 14.1 at idle?

That is a normal range on the alternator putting out that voltage, anything over 15v is overcharging, and falling under 12.5 volt is bad regulator.

13.4v is normal.
