I'm not sure how long I've had this problem, I don't drive it at night too much. Last evening I noticed my dash lights weren't on when it got dark enough to tell. I came home and realized the PARK lights weren't working either. I have constant power on the green/blue park light solder spot, no power at the the green/white dash light solder spot. If I jumper to the dash light solder they work but the constant power to the green/blue park light solder has me confused, which is easy to do with wiring. Can anyone offer me some ideas? opinions? facts? '77 280Z, build date 09/'76, I've been reading Z'sondabrain thread. Thanks for any replies.

The G/L wire comes off the fusebox. It's the wire that carries 12VDC+ to the switch. It should be hot all of the time. The switch then makes contact between the G/L & G/W wires. The G/W wire then carries the voltage to the light.

I've found a good write up from MikeW on how to fix my problem, hopefully. I'll have to take that box apart and fix the rocker plate on the left side where my dash and park light contacts are. Nice rainy weekend to sit down and tinker.

That was easier than I thought. Anyone who hasn't yet should spend a few hours cleaning this switch, I've got lights I don't remember having. Headlights are a steady beam now and my dash lights are brighter too. Thanks again to MikeW.
