Great GMCMI event. But now that we're home. I need to replace some of the electric switches that went unused for 20 years next to the Iowa corn field. Bob Dunahugh 78 Royale

Bob,
If you wish to keep your original switch, you may find it just has several bent tabs on the back holding it together. If so you should be able to open the back of the switch and clean the internal contacts. Be careful when opening the switch as the contacts are spring loaded and may fly out. Note the position of all the parts as you disassemble it.

If the switch isn't making a good contact for carrying the load of the pump directly, you can wire the switch to a cube relay and power the pump through the relay contacts. The switch then only carries the coil relay (~ 75-150mA) vs 10Amp + for the pump.

Bob, I have the panel but the gas gauge is broken just as your's was. I think the switches are all fine if you need them. Let me know, Hal

Hal. I would be interested in the panel if Bob does not need it or want it. Please let me know. I have a crack in mine and a few of the light connections in the back are beyond repair. Thank you very much


My switches all work so I don't even need those if you want to pull them.
