Nola280

Charge light only comes on with the engine running, nothing happens if the ignition switch is set to On without the motor running. I'll try to trace the harness the rest of the way back and see if I can find a short. I've never been much good at electrical work. Any tips or common issues to look for while I'm poking around in there? If I've got to dive into it, I want to make sure I get everything done that I can while I'm in there. Thanks for the help!

Hi y'all, Sorry if this is a repeat, but I haven't been able to find an issue quite like this in the forums. I've got a '76 280z that I purchased with a 5 speed from a later car already installed. The reverse lights stopped working a few weeks ago, so I checked all the connections, replaced the switch, swapped bulbs, and I still get nothing. The strange thing is that when the car is running and I shift into reverse, or press the switch manually without it being installed, the red "charge" light in the voltmeter comes on. There is some voltage coming through at the sockets, but not a full 12 volts. All other lights and switches function perfectly, I've checked the FSM to insure that the wires I'm plugging into the switch are the right ones, and I know they're the same ones that came off the old switch because I removed the old one and installed the new one myself. Has anybody out there experienced anything like this? Any help at all would be greatly appreciated. Thanks!
