Re: headlight switch grounded?(UPDATE)

[Dan McCormack <mcwheels@xxxxxxxxxxxxxx>]

I'm glad it worked out Mark. Like I said I had an epiphany yesterday morning 
( I do my best thinking on the John lol) and I remembered that there's 2 
different sources of 12 volts that went to the headlight switch and I was 
betting that one of yours was dead. That's a new one with the fuse box 
however. I thought maybe you'd find the same problem I've had a number of 
times with that fuse. There's so much power going thru that fuse when the 
taillights and brake lights are on that I've had fuses that weren't blown 
but melted the solder in the fuse that holds the metal cap on. The one on 
the 66 Charger I had (6 taillights and 6 brake lights) would get so hot 
you'd burn your finger on it.

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

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.
