I had the dash out of my 68 El Camino and I replaced all the bulbs with the correct ones (#1895), and when I pull out the headlight switch one notch for the parking lights and the gauge lights to come on the parking lights work but no gauge lights. When I pull the headlight switch out all the way,the headlights work but still no gauge lights. When the headlight switch is completely pushed in all the way (off pos.) the fuel gauge works as should. If I pull the switch out one pull or to the next pull out the fuel gauge drops down to "E" position. Is this a bad headlight switch or some kind of a ground problem and where ??? I have 2 other 68 headlight switches (used ones) I tryed them and they act the same way. I hardly think that all three switches could be bad. PLEASE HELP Thanks, Mark

may sound simple, but is the fuse ok? I think the dash lights have their own fuse on the distribution block. Its the short stubby one. I think it is an SFE4

I allready changed that too.

when you pulled the dash, do you remember disconnecting any ground wires? my '72 has a ground wire at the headlight switch and one that attaches to the dash frame left of the steering column. dont know if the 68 is set up the same way. but i would make sure you have good ground as a first step.

Are the tail lights working? If they are:
Measure voltage to ground on the dash lamp fuse clips. Don't touch the fuse. Bite in and measure the clips. Do this with the knob rotated to full brightness and the headlights on. See if you get a reading.

Yeah , I found the problem why I didnt have dash lights. It was missing a ground wire from the gauge cluster to the dash frame (metal). Once I hooked up a good clean ground wire there,everything works as should.
