Re: headlight switch grounded?(UPDATE)

[chymar01@xxxxxxxxxxx]

Fixed! 

There was no power going into the B2 plug at the headlight switch coming from the brake switch. Found a loose connection between the fuse box and the brake switch was the problem. 
It was odd because I had power at both sides of the fuse. I flipped the fusebox over and had no power coming out the back side to the actual wire going to the brake light switch. I tightened the terminal end and cleaned the fuse side and then I had power. 

Thanks to all the folks who replied!

Mark I had to think about your problem overnight and this morning the light 
came on (pun intended) and I think I know what your problem is. The dash 
lights have a separate fuse that comes after the headlight switch but they 
also get their power from the taillight/brake light fuse which comes before 
the headlight switch. There should be 2 sources of 12 volt power going to 
the headlight switch. I think one is marked B1 on the switch and the other 
is marked B2. One of those is just for the incoming power to the headlights 
and the other one is for the incoming power to the taillights, parking 
lights, dash lights and in some cases the brake lights. I suspect the reason 
that your lights are working when you jump the switch is because you're 
jumping it to the headlight power and not the taillight power which in your 
case is probably dead. Go back to the fuse box and check the fuse that's 
marked taillights or brake lights. There should be power to both sides of 
that fuse at all times. If there's only power to one side the fuse is bad. 
If there's no power to either side then you have a problem with the wire 
supplying power to the fuse box, might be in the bulkhead connector. If you 
have power to both sides of the fuse then check to see if you have power to 
both the B1 and B2 leads going to the headlight switch. They both should 
have power even with the key off. 

Hope this helps, Dan 

Btw on a side note if anybody would like to have their parking lights stay 
on with the headlights like the new cars it's a simple fix. Take the parking 
light wire out of the harness going to the the headlight switch and splice 
it into the taillight wire.

Brake lights also run through the headlight switch. I've been over the 
wiring diagrams a hundred times bu now. 
Printed circuit board is OK. If I run a jumper from power across the 
switch(es) to where the dash lights and parking lights get power they work 
fine. Same with the brake lights. 
I just can't see FIVE different switches all being bad.

NO, it doesn't have to be installed. Dash & interior lights could or 
probably will be a problem with the dimmer portion of the switch. Turn the 
knob back and forth to see if lights work or blink. Brake lights run 
through the turn signal switch that is usually were that problem is. Also 
check the printed circuit board on the back of your instrument panel for 
thin sections burned open.

Hey all, 

I'm in the process of fixing the melted wiring in my 64 Polara. 
Does the headlight switch have to be grounded(to the dash I guess) to work 
properly? 
I've tried several switches and I have no dash, interior or brake lights. 
This is with the switch plugged into the harness but not mounted to the dash
