my 82 is acting funny the fuel gauge bounces when driving and now when i turn the headlights on it goes half past empty and dont move it does not bounce there it acts like it is grounding but checked all the wiring and all is good and there is no gauge lights when i hit the high beams the head light go out all together but the blue light in the dash is on and it is also on when just the top lights are on when i shut the head lights off the gauge goes back up but still bounces i seen my high beam harness to the floor got hot at some point and melted so i am going to change the harness and put a new swicth in but there got to be more problems then just that right any help would be great thanks

Check the ground commin off harness to dash. the ground is to the left of stering wheel under dash . I had a similar prob not long ago wound up being that ground

If I remember correctly, the ground wire that slingin mud mentioned is hooked to the park brake pedal assembly. If so, you might check the mounting bolts for the pedal assembly to make sure they are tight. I would also check the battery to body and engine to body grounds, and the main harness plug where it goes through the firewall. Hope that helps, best of luck.

ok so at lunch i put on a battery to body ground and an engine to body ground with no aval i also put in the new floor mounted dimmer and the wiring harness because the other was fried

now here we are when i turn on the headlights the blue high beam light is on in the dash but the highs are off when i turn the highs on the light goes out complete oppisote of what it suppose to do

i also noticed i have no dash lights at all just the single heater light and the gas gauge still goes 1/2 past E i checked all fuses and grounds all seem good

my next question is could it be the circut board on back of the instermunt cluster causing all of this including the gas gauge problem when i had it out it was rough i could plug in one light and five other would go out in the dashborad thanks

Yeah, they don't go out real often but if you've checked everything else, that really doesn't leave much more to check.
