Putting the dash back together in my 66 Chevelle Malibu and have come upon a grounding issue, i think. I upgraded the idiot lights to gauges, and therefore ran wires for the new ammeter, Before reinstalling the dash i have tried to get the dash lights to work (the 5 backlit lights that are on Grey wires). I thought that i should be able to turn on the lights, and simply put a ground wire to the metal part that holds the lights to the back of the dash. This did not get the bulb to light. However when i put a positive lead to what i thought should be the ground connection, the bulb lit up.
i tried disconnecting all of the new wires that i installed for the gauges (and Vintage Air AC), and still get the same results. I am assuming that the back of the dash (metal ) is supposed to be negative ground, and that i must have a short in the wiring harness.

Any ideas or info would be greatly appreciated.

Glad you found the problem. Another lesson learned here is to test things as much as possible before reassembly. Your troubleshooting would have been much more difficult if your dash had already been installed.
