Seems like the only thing constant around here is change.
When I got out there to reinstall, so I could test the ASI with the engine running...
Decided to take the regulator out and check out the brushes.
Yeah... I'd say we have a problem. They are almost gone.
Didn't even do the ASI test. Just put it back together. I'll take it to oreilleys tomorrow and have it tested just for kicks and grins. But I wonder if brushes being that worn, could cause the overcharge condition?

The rings could be badly worn as well, for all I know. But they feel like they are ok.
Thinking about just getting a cheap rebuild kit from ebay or amazon.
Discovered that the other alt I have, (On the old, now 'parts' truck...), is also a 3g 130. But it is the belt/pulley type. So the housing is different. But.... I'm pretty sure the regulator from that one will swap right over to this one. And if it comes down to it, if the insides of that one are better, I wouldn't be averse to cracking the cases, and swapping everything out...
Probably not going to be really back to work at this until thursday.
