Had similar no-charge from 32v alternator on port engine. This was a Delco unit which was built like a tank and I was dreading having to find a replacement.

I ordered a new voltage regulator online for $32 and I'm a happy camper again. Took only a few minutes to install the VR (once the alternator was off the engine).

If you have a Delco and need the place I ordered the VR, just let me know and I'll locate that info for you.
