gauge circuit board

All illumination is same circuit same orange wire. This wire is weld splice forked in the harness to feed the 2 circuit board connectors. Radio dial light, ash tray light, shift indicator light, all on the same orange wire circuit. There is a fuse for this single circuit, and a dimmer rheostat in the headlight switch.

After a quick check I have power on the orange wire going to the dash. I ended up pulling the dash from the car. I made a fixture to test the bulbs and discovered that a few of them were blown. Than I rigged up a way to test the bulbs in the dash before reinstalling the dash and most of them wouldn't work. Ended up having to clean the bulb, housing and circuit board connections. Everything worked on the bench. Stuck it back in the car and it didn't seem to work until I turned the garage lights off. I forgot how dim these car dash lights are compared to the newer cars. But I got all the dash lights working now, just need to get to the turn signal switch to figure that issue out yet.
