86 NA- Wondering if you guys knew what would cause these:
1) The interior lights fade in and out, regardless of throttle
2) Voltage meter goes up and down, regardless of throttle
3) The heater cuts in and out, but most of the time it doesn't work, it fires back up when i hit the brake though
4) When it's idling, it goes up and down between 900 and 1100

Thanks dudes.

have the alternator tested, sounds like the internal voltage regulator is going away. if the computer doesnt get the correct voltage you'll have all sorts of mysterious symptoms.

i agree with chezam on this one........ go to autozone...... they test for free.
You might want to check the wiring to and from the alt. this also could be caused by a loose ground or power wire.
