I am having some weird symptoms with my 82. When I push on the brake pedal, the headlights turn off, and the windows do not work. I have traced the wires EVERYWHERE. I can't see anything wrong. Can I be missing something? Any link between these things?

 

One possibility is a voltage drop due to a bad ground or dirty connectors especially at the fuse panel. Start with the battery ground and work forward. There are grounds above the fuse panel, on the left side of the block, on each side of the headlights, on the engine and at least one other that currently escapes me.

There are a total of 7 ground points. Some easy to get to others you will need to lift the car and climb under. I will try and get you in the right area.

1) Battery negatice pole to body in the trunk.
2) Two points seperate points above the central electric board.
3) Engine ground to body on right side member.
4) Ground point on front left cross member.
5) Ground point on front right cross member.
6) Ground point underneath instrument panel next to steering column.
7) Ground point in trunk at rear right underneath trim panel. (you have to remove the trim panel for access)

This was taken from the shop books. I am going to start trying to find them on my car and clean them. I found this topic while I was looking for another one that talked about electic problems. I dont know if you should put any kind of protector over the ground to keep it clean.

Good luck <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

 

Hi Sharks:

Welcome Ell and Mary. I like your contributions.

See this discussion for more data and pictures about grounds. Here are some excerpts too.

2 coil or engine ground cables. (Right side cable goes from coil bracket bolt to topmost front timing belt cover bolt. Left side connects at bottom rear of back timing belt cover.)

Listed as follows in the manual:
-Battery negative to body
-Above and behind central electrical panel (2 points)
-Engine to body (under passenger's side)
-Left front cross member (to left of headlight motor)
-Right front cross member (passenger's side)
-Under instrument panel by steering column
-Under right rear side trim panel (inside)
Additionally, my fuel injection harness is grounded to bolts on the passenger's side valve cover.
