Alternator Overcharging

67Dar273- Thanks for the information The voltage for the Harness Test was 1.3V and the Ground check was less than 0.1V. So the problem seems to be the harness.
I would like to try testing before commuting to a relay. My thought is to cut IGN1 coming out of the bulkhead and just temporarily jumping a wire for the starter relay to the engine bay side of the ING1 wire. If that work's then I will feel confident installing the relay.
Based on your description of the relay, this is how I think it should be wired.
Does this make sense?
Thanks
Mike
