DON'T ADD A GROUND JUMPER TO THE VR CASE - IT'S UNSAFE.

If you have an alternator ground fault, and add a ground jumper to the VR case, ALL OF THE CURRENT GENERATED BY THE ALTERNATOR WILL FLOW THROUGH THE JUMPER, 20A or more. You could start a fire. DON'T ADD A GROUND JUMPER.

Instead, if you suspect you have an alternator ground fault, measure D- with the car running. If you get a value more negative than -0.5 V, then your ground is bad and must be repaired.
