Only the DASH Illumination Lights don't work
#11
Most likely the headlight switch or the connector to the headlight switch. Did you measure the voltage at the fuse? No voltage at the fuse with the switch on and turned to full bright will confirm that the problem is prior to the fuse (headlight switch), and not in the wiring after the fuse.

I have a similar problem. No voltage at either side of the fuse with rheostat full clockwise and switch pulled out to the first detent. All marker lights and tail lights working. Is this almost surely the switch if the fuse is good? Interior lights light up when rheostat is full CCW.

Most likely either winding in the rheostat is broken or the brush (carbon rubbing block) Is missing or worn out. The other possibility is the wire connection at the headlight switch or fuse block is bad, also possible that the wire has been damaged.

Thanks Don. I thought getting the car running was going to be the hard part. Now it's getting everything working properly so I can pass inspection.

The details are what are time consuming, and sometimes frustrating. It's amazing how long some seemingly small thing can take.

The problem remains here...replaced the switch with an original Ford product still in its box...$$$$
Still no dash lights, but all of the warning lamps and gas gauge remain working.
I also noticed the climate controls do not light up; as they are married with the instrument lights.
I'll need to chase the wiring to see where I finally get a current and then move forward again from there. however that is now placed on hold as I just found another problem that has reared its ugly head; it appears my brake booster is making a sound under the dash similar to a woopy cushion when the brake pedal is compressed. The brakes then become extremely hard to compress. After a few pumps, the power assist returns and it feels normal. Not sure if the diaphragm is unseated or ripped.

...and a Whoopee Cushion sounds like a fart, so that's an amusing problem you've got there. I wonder if Monty Python ever did a skit about a farting car?   Big Grin
