After buttoning up the 964 yesterday, a brief check of the running systems found an alternator that was charging at 19 volts, which is not good. Normal charge is somewhere around 13v, and over charging can lead to electrical problems in the car. The voltage regulator on the back of the alternator is what regulates the charging voltage, so that is what was needed.
Unfortunately, on the back of the alternator, means a lot of stuff has to come apart, lol..
Voltage regulator pulled out of the alternator
This is the guy. A new VR and we were back in business and the car was on it’s way.
