1982 TOYOTA SUPRA

I have an 1982 Supra, and The charging system will not charge, (same as a previous post, 1989 Toyota, Supra Turbo) I have replaced the alternator 2 times, replaced both my ground and lead cables, replaced the in-dash relay (they called it the charge-lamp relay), Replaced the battery, basically everything I can think of. The alternator is a lifetime warranty, and very expensive, I didnt go cheap on this, I have learned in the past from that, but I will be trying my 3rd alternator. Is it possible that I have had 2 bad voltage regulators? Or am I missing something here.

Resistance came back at 0 on charge wire and ground wires. I actually ended up testing voltage to the regulator on the back of the alternator and It was getting readings (I didnt think it was) and figured out it was just another bad voltage regulator. Replaced the alt since the regulator is built in, and no problems since. Wierd. I would think that the regulators were more dependable than that.
