In general, if you disconnect the VR from the DF terminal on the generator, it will stop generating. If it keeps on generating then there is a short in the generator field windings (or leads) to ground. If there is no short here, then the only way you can get high output voltage is from a bad VR. Personally, I have never seen a VR fail such that it gave high voltage. OTOH, if you had a short to ground of the DF wire, between the generator and the VR, this would alco cause this problem. Take a good look at your wiring harness and make sure that it has not been damaged or that you don't have some body panels coming loose and cutting into it. > This was on the older(?) style of generator with the push on terminals.

That style was used only in 67 and 68. The push on connector really wasn't up to the 30A, so there were too many failures of that connector and they went to the screw terminal and eye lug in 69.
