88 Gl ea82, aka mountain grizzly mk2.
This week on my way home from the garage, I noticed my voltage gauge was just below 12v. Made it home with a dead battery. I figured I would replace the alt the following day, but I'm not sure if the spare I have here is good.
My problem seems to be more than the normal failed alternator though. When the key is turned to run, I have no warning lights at all. I've checked all the fuses and fuse links with my power probe and everything checks out. I have a good ground at the alt, battery, and to the body. I swapped on a spare alt, and still have the same issues. I have battery voltage at both pins at the alt, and at the main charge cable. The battery is new, as are the terminals.
Am I missing something here? I have a maxima alt on order, but it won't be in for a few days. Even if it turns out this is a wiring issue, I don't mind swaping in an upgrade. This car has 290k on it, and I have no idea if it is still wearing it's factory alternator.
