Recently installed a LS1 in my 1987 944 turbo and immediately noticed the voltage gauge bouncing. Never an issue with this gauge in the past. I have done some reading online, but haven't found a ton of info on this issue. With the engine running, I am reading ~14.45 Volts at the battery terminals. Any suggestions other than checking all the grounds?

I'd check the wiring connector at the voltage regulator and continuity through the harness of those wires. I had that bouncing needle issue on an old Blazer and it was a broken wire near the regulator.

I think you were on the right track. I did some research and went ahead and had mine rebuilt as a 1 wire alternator. I think the regulator was shot and the gauge was showing the A/C output of the alternator. All good now, comes on at idle and charges solid at ~ 14.6V.
