Okay, I haven't been on here for a while, things have been smooth. That changed on Friday. Driving my 66, the battery gauge suddenly jumped really high, then dropped really low - never came back up. Took things apart today to find that the hot lead on the alternator is melted out - I mean gone. Took the alternator apart to find that a wire on the inside had actually grounded to the casing, which likely has been a problem for a while.
So, I got a new (rebuilt) alternator in it. Everything hooked up okay. Started the truck, and the generator light is on. First time I have ever seen this light. Battery gauge is showing around 7, which I knew would be low as I only had it on the charger for about 30 minutes. All electrical items work. Ammeter is barely above 0, but does go up when I give it gas. Just want to know, is the generator light on because the battery is low? Or is there another problem?
I forgot to mention that it has an external voltage regulator.
