Tested the fuel, oil, and temp gauges today, using the little hack in the latest issue of Mopar Action. Fuel gauge tested fine, but I could get nothing from the temp and oil gauges. I pulled the same 3 gauges from a '76 RC dash, and all 3 tested as working, and the needles are in better shape. I'm painting ALL the needles tonight. This truck was missing the voltage regulator for the gauge cluster when I bought it. I put one on it from Rock Auto, but those 3 gauges never worked. I've picked up one of RTE's versions of this to install.

I took the amp gauge out of the cluster for closer inspection. Both posts are solid; no movement at all in them. I'm reluctant to do any soldering, since they are still tight. I picked up some brass nuts to use for reassembly. On the back, are these black-ish squares the insulators? I have a can of Deoxit on the way. I will clean all posts, pins, and the spots of contact on the back circuit board area again, and will then reassemble everything.
