There are a couple of different styles of the early voltage regulator. I am not familiar with all of them, most do have a ground wire to the metal case, especially if the regulator is mounted to the firewall with the rubber bushings. The rubber bushings 91A-10610 will electrically isolate the regulator case from the chassis. The regulator circuits require a ground path and ground wire 91A-10611 was connected to the regulator case by a small screw and to the mounting screw that passes through the rubber bushing 10610.
