GAUGES NOT WORKING

[moes]

I have a 1970 Satellite. I had my dash cluster out to fix my tachometer, now the gas gauge and temperature gauges are not working. My ammeter is still
working. They were working before I took the cluster out. Thanks

How about your turn signals? Wipers? I'm going through this exact situation today on a '70 Road Runner. I'm 99% sure the problem is the smaller of the two plugs where the column plugs into the dash wiring harness. Those pins can "slip back" and not make good electrical contact. I ran into this years ago. Today, I plan to pull the plate off that supports the column and push in all the pins (both ends) one-by-one with a tiny screwdriver.

took the cluster out again, reinstalled it, everything works but the temp gauge now. Checking wires now

One other thing I ran into is those tiny pins at the back of the gage cluster where you connect the 6-terminal (?) plug (rally dash). Those pins are not very strong & I broke one off once. I was able to fix it with a piece of wire inside (pins are hollow) and some epoxy, making sure I kept the pin itself clean (for good electrical contact). You could also use some copper-filled epoxy (conducts electricity) like they use for rear window de-fogger repairs. Good luck

Everything in Mopar land is great now. All fixed, pins on the back of the cluster were dirty, cleaned them with some emery cloth, added some dielectric grease and everything is working the way it should.
