There is a, thing, that looks like a roll of dimes that is bolted to the engine bay wall under the voltage regulator like a ground and wired to one of the pins of the voltage regulator. I think its called something like voltage reducer or something like that. Its definately original to the car. Without getting into why cause that will just confuse the issue. Wondering if its possible and how to test it with maybe a regular voltage meter? Because to replace it would be a guess at what it even is and then would have to cut and splice the wiring cause they dont make them like they used too. I doubt Ill get a reply to this but if I do and you know what im talking about, I Will be impressed! Thanks, I know this sounds sarcastic but seriously, I doubt anyone will know. I gotta try.
