Alright, still cannot get my charging system to work! Fbody69, I'm not sure if the system worked before the gauge conversion, but my guess is that it didn't. I was having problems with my battery (which since has been replaced), and I wouldn't doubt that part of it was the system. I hooked up the brown wire, and I still get nothing. The voltage regulator is connected tightly to the engine bay - it should be getting a good connection. I DO NOT have a ground WIRE connected to it - does it need one?

I also tried the following: I connected my voltage meter directly to the post on the alternator. I ground the meter to the negative battery post. I started the car and did not get acceptable meter readings. I really think that the alternator is the problem. I think I will have it re-tested. Am I on the right track? Another question: Does the alternator need to be grounded? It's got a "ground" post on the back of it. By the way, I tried grounding it, and still no luck.
