Any suggestions are appreciated. I just went for a quick ride in my fuel injected 75 914 1.8L. I noticed along the way the RPMs were showing "0", no voltage showing, the red alternator light was on...BUT when I got home and started it again, I checked and the alternator belt was fine and was turning the alternator. No fuses had blown. I am running a new/fully charged Optima R34 which allowed me to start the car several times in this condition.

Does this mean...a new alternator?

Double check them fuses. Bet you kicked one out. BTDT.

And now we both have-many thanks-couldn't see the melted aluminum on fuse #9 with the clear cover on. Many thanks-solved the issue.
