67 c10 instrument panel schematic and 'terminal next to battery'

[67alldiy]

thanks for the help

I actually have two headlight switches and tested both and the same symptoms are there.

I have now also replaced the brake switch.

What I am down to now

Car runs and shuts off fine, one time the dash lights and running lights came on . applied the break and everything shut off

I have checked the headlight switch and am only getting power to the head lights. I do have a 12v and good ground.

I get no parking, dash, dome AND brakes/rear running lights

******
Tail Stop, Dome, Park
When checking for voltage from both sides of the fuse under dash it actually sparks and burns up the fuse. Almost as if one side is grounded. When checking connectivity with ground, that same side does show connectivity?

I do have a good 12v side(left side), just wont transfer through the fuse like the others(checked all others and they were good)

New Turn signal, fuses, brake switch, tested headlight switch

Any help is appreciated

Is this a question? Or are you telling that you have a wire that connects to ground?

If you have continuity to ground on a wire, you need to fix that. You may have the insulation on part of the wire worn off, eaten, or deteriorated, and touching the body of the truck. Remove light bulbs and disconnect plugs when checking for continuity or shorts to ground. Suppose you have a wire that goes to the tail light at the back of the truck, and you have the bulb removed and the wire unplugged. If you have continuity to ground on that wire, you need to examine the wire. My tail light wire that runs from near the gas pedal where it leaves the cab and goes under the truck was also partially eaten by rats where it goes up over the rear axle, so I had to solder-splice in repair sections. It was shorting to ground.

start with the easy things first

after stepping back I went and tested the original signal switch and it finally kicked my lights on (no more burned fuses)

summit racing sent me the wrong part. even more reason to really take your time and ask questions. summit had 4 different part numbers for my truck

advance and o'reilys had a few in stock and found the right part

my brake lights and headlights are working however I still do not have dome and rear running lights

checking grounds and schematics .

lesson learned
