Confirming that a Late model SC ALTN is compatible with 3.2?

I think my new Valeo ATLN / internal VR is bad. I can’t shake this over voltage problem. Randomly still fluctuation with Revs and then the fun starts. Not as high as it was but 15.V is not where I want to be. Lights really get it going..

I want to use a buddies SC ALTN with internal VR as a final test.

Batt is good

Replaced , isolated or serviced every
Motor in the car.

Grounds are checked.

Yet the Voltage wil just go off. Fried my blower resistor in the process.

Nothing I can think of will cause over voltage except a Bad cell,
ALTN, VR, or a motor..

Different alt for SC vs 911 3.2, e.g. SC 6mm studs vs 5 mm for 3.2

If you can find a spacer to make up the difference in height it will work. They're out there.

Good point. I can return my Velao under warranty so I’ll do that.

Is the VR the same? If so I can pop one off and into the other. Just don’t wannna pull it all apart.
