Well a big thanks for pointing me in the right direction.

I didn't have time to pull the instrument panel out or figure out which was the correct wire at the junction so I just put clipped a test light to the 2nd terminal on the alt.

Probably not the best way but I got positive results. 14.5 volts at idle. and 14.13 with the lights and heater on. My stress levels have dropped a ton.

None of the warning lights in the area of the charge indicator (left side of the panel) are working. (other than the parking brake and high beam indicator)

Seems unlikely that all three bulbs would be burned out but I'll check that.
Is there a known fault in the instrument panel circuit board that could be responsible for this?
