big volts

after supper yesterday, I did put another good battery on it and checked the batt, vr, alt outpost post, and ball with KEY ON. getting about the same reading except when I put meter to body of VR and gr at batt, the reading was less 3-5 V rather than 8-10! LOL

did basically the same thing to this second batt, got about the same readings except again less at the VR body. AND with this second battery, the alt bug lug showed 14.7 instead of 16-18...

I can see the starter relay and VR are showing age. I will pull on an new VR I have and a starter relay off another car and get some readings.

I can also run some of those other tests 73 AbodEE listed. my meter is not old at all but is cheapo H F model. it will sometimes BOUNCE from like 1 V to 18 getting these weird readings. thanks for the help and I will list results back later today..

You are still getting too much voltage on the case of that regulator. Try, as a test, running a wire directly from the battery negative post to the case of the regulator. This will assure that the case of the regulator is at the same ground potential as the battery. Keep us informed.
