Just for S&Gs I'm gonna take the alt down and have it tested. I never removed the PC or any of the bulbs from the pod. I got under the dash and checked, the gauge housing is grounded as it should be. I'm not sure if they make a replacement PC for the stacked gauges. I did have to charge the bat awhile back and I'm not sure I disconnected the cables. Maybe I shorted one of the diodes w/ the charger.
