94 5.0 wont charge

just replaced the alternator and i'm not getting a charge. the battery, and wires and connections are good. is the voltage regulator part of the alternator or is it a seperate unit? could it be the pcm?

Why are you assuming the replacement alternator is good? Have it tested.

A better question is why he assumes the original alternator is bad?

I fail to see why that's a 'better' question, but when the old alternator was in the car and not giving a charge, it was also assumed that the original problem was a defective alternator, and a defective alternator could STILL be the problem; only testing will tell.

I would think the smart thing to do would have been to test the original alternator. When you start assuming things it gets expensive. He may just have a bad connection somewhere or a burned fuse link.. Bob

Usually with internal avr there is a full field test point where you fully ground it and get full output, you have to turn on all accessories etc cause if you don't the voltage will jump excessively, you do this briefly and monitor voltage and remove the wire once you see voltage spike. You then know if the basic alternator is ok or its the voltage regulator. Also never overlook the battery, as there can be bad cells or intermittent bad cells within the internal workings of the battery.
