The alternator in our 76 GMC stopped working indicated by the idiot light.

I had installed this alternator in 2007 with a 100 Amp Bosch rebuild from NAPA.

I took it apart and the recifier and triode were both fried.

Since this alternator was not that old ( but out of warranty ),
I decided to replace those components rather than replace the entire alternator.

I checked the stator and rotor for shorts and didn't find any.

I installed it today, fired up the coach and checked the ouput voltage. 17 volts. And the alternator was getting hot.

Is this a voltage regulator problem? Or something else?

Appreciate any advice.
