UPDATE! The ammeter is now working as it should. I took my cluster apart to paint the needles and add a vac gauge, and I noticed the ammeter needle seemed to be "spring loaded", so I wound it around in a clockwise fashion until it was straight up and put the cluster back together, and now it shows a slight charge when idling, and the needle moves left slightly when I turn the headlights on. If I rev it up the needle moves to the right slightly. The truck has been sitting for about 2 weeks w/o being started, so I expected the needle to move to the charge side, as it did before when the needle was leaning to the left at rest. I wish I had an explanation for it, but I don't. Thank you to all who offered help and made suggestions.

Thanks,
Mark
