I have a 77 280z. owned it since 1985. I am experiencing a strange electrical problem with it. It is similar to other post I have read. I have an idea what it could be but would like to know what you all think. I drove it one night and 15 Min's into the drive my dash lights went out. I took it back home and realized I didn't have side maker or tail lights. I don't drive it alot. And haven't driven it at night for several years. Then I started checking everything to see what else was wrong. Well lets see, volt gauge doesn't register voltage if the doors are open?!, Close them and it shows normal voltage. Dome light doesn't work, all dash lights don't work that includes stereo, etc. Headlights work so it's not on that circuit. Horn doesn't work. Now here is the kicker, if I start the car everything works! except dash and marker lights (parking lights) I found a disconnected wire on the combo light switch. held it in place and the parking and tail lights and dash lights came on. So that fixes that problem. I just have to figure out why it came unsoldered from the combo switch. I have a feeling it is getting hot (green with white stripe). So why no horn, dome lights, and the drain on the volt gauge with the doors open? I've looked at the wiring diagram and am missing the obvious, obviously. Anyone have an idea of what I'm missing? Could it be the ignition relay? Any help is appreciated. Bob
