I have had intermittent discharging from the alternator for a while. I found the single small gauge wire plug on the back of the alternator was clipped in place but apparently not making good contact. I unplugged it and cleaned it good and snapped it back in. Charging was good again, until this morning on a run into town. The gauge got down to about 10 volts or so. I didn't dare shut the truck off so I made it home. I jiggled the plug in and bumped it. The voltage came back up but went right back down. So I removed the alternator and opened er up. To my surprise the brushes and bearings look good. I could not find anything loose or broken. I believe this is the original unit with 83,000 miles on it. I slightly twisted the single blade terminal in that plug in hopes of making a stronger contact. If it happens again I guess I'll have to have it rebuilt or buy a new one.
