Alternator Light Does Not Go Out - Fix!

I have for sale the parts to fix the following issue.

UPDATE! All the sets are sold.

I’m selling 9 sets for $10 each plus $3 shipping (continental US) on a first come, first serve basis.
Please email me: 911-Porsche@comcast.net



The following tech note explains why some have issue with the alternator light not going out after the engine starts on 74-83 models. The typical symptom is that the car starts normally but the alternator light stays on until you blip the throttle to 1500rpm or so. After you blip the throttle, then the light goes off and all is normal.

There is a Porsche Technical Bulletin that deals with switching alternators or voltage regulators to internal ones. This fixed my light issue!!

The following link explains it all: Alternator light doesn't go out after startup

I had to purchase the parts in bulk and have nine sets for sale. First come, first serve.
