I have tried and installed two gas gauge via classic parts. I believe needle moves when ignition is turned on but I still have no gauge which works. First phone call response via Classic was to make sure solder between power terminal and sending unit terminal was grounding out to the bezel. With this I am trying to verify by doing the following, pulled gauge back and out to expose, I show power at the power terminal with ignition on and also show power at the sending unit terminal, and of course at the sending unit terminal. If i pull a ground from chassis to the solder point between terminals it sparks! (New sending unit installed) Questions: Am I testing correctly? Should I have power at both terminals with key on? If power at both is gauge made wrong where it it not separating the ground solder ground? Should I get the spark when I try to ground the solder ground? Maybe I'm drinking to much when troubleshooting? I wish Now!
Michaelr, re-post this on the 47-54 forum. It gets more traffic and most of us have had issues in the past with the gremlins! Ken
