voltage from alternator

[pro321a]

Does anybody know what the voltage readings should be at the plug at the voltage regulator? Still chasing battery light on with good output to battery. Thanks.

Depends on a few things... 13.2 -14.2 volts is the range I would expect to see.

Varies based on battery temp model, RPM.... yada yada yada...

or are you talking the three prong plug?

Yes,the three prong plug. I believe the yellow wire with the white tracer is for pcm signal?
