I took care of one nagging issue today... About a year ago, I pulled the IPC to replace a couple burned out bulbs. In my rush to put it back together, I messed something up (It was my DD at the time). Everything would work fine during the day, but when I pulled the headlight switch at night, the gas gauge would fall to "E", the door buzzer would faintly alarm and the high beam indicator would half light up. After a little googling, I decided it was most likely a bad ground. (Yes, I googled before I asked. Crazy, I know!) So I pulled the IPC back out, sanded the contacts on the bulb holders and the PCB with some 2000 grit and checked everything with a DVOM before reassembly. Put it all back together and all is well now. It was weird having actual screws holding things together and not just plastic clips. 1984 seems like a different world!
As I'm typing this, I'm thinking there's a high probability I forgot to reconnect the speedometer cable. That's tomorrow's problem. I may have been delirious from the heat. It was 105° in the shade.
