y would my gl warm up with my headlights on. then to lets say i get gas and i go to turn it back on and the headlights wont turn on after i start it but while its cold it doesnt seem to do it. it pisses me off. i can let it cool down and they will turn on.

The light switch makes a ground return for the lights. The trouble may be with the switch. I suspect a bad connection is heating up and causing the trouble.

Could also be the ignition switch.

My '85 BRAT will startup and idle as normal, but at times,, some of the "key on" functions don't work. Turn the key a bit, and things work.

ya i think it might be the ignition switch it does seem to have problems but i havent been able to make it work any way other then letting it cool down. it doesnt ever shut down while they r on. just when i turn the car off then on again after being warmed up.

Still, next time it does it.. Try twisting the key just a tad more, either dirrection. See if it helps...
