No need to test the resistance, I bought a new one for less than 10 bucks. The old one was cracked and just fell apart when I unbolted it from the firewall. The schematic above is a good reference though.

The IVR has nothing to do with the instrument lights. It's one pin on the panel that gets its voltage from the headlight switch. It should be easy to trace back.

I could use that but you're too far from N. CA

Now it makes sense. I bought a new dual resistor anyway, everything's working. I also bypassed that ridiculous seat belt interlock relay by hooking the 2 yellow wires together.

Point me to one. My bottom resistor has a horizontal crack in it, most likely not the proper resistance now but still working.

There's a lot of bad advice in this blog, jumping to conclusions with no troubleshooting at all. If I had that car I would pull the instrument panel out of the car and get things working on the bench. It sounds like your instrument voltage regulator is the place to start. Since it's a Valiant...

I have a 74 Dart, all stock wiring and working well. My question is, what's the purpose of a dual ballast resistor? I know the top one is used to drop voltage and supply the ignition coil but what's the bottom one for?

I have a real nice fender for a '67 Plymouth Barracuda. I had it sandblasted (except for the factory rustproofing on the inside) and worked on it a bit to get it looking really nice. The hard work is done, I'd use it on my car. This fender is 57 years old and hard to find. $800 firm...

That's interesting, I'll look into that when we get a warm day and a good helper.

I took a wheel off the rear and rechecked. I am running 3/4" bore size in the rears.

I am running 7/8 rear cylinders, it helped a little but they still lock up.

Just to reiterate, I have power disc brakes, all factory setup for '67. It has never worked right, poor braking. Fronts won't lockup, rears will which makes it dangerous. I suspect either bad master, bad proportioning valve or bad bleeding of the system. In any case I want to change the...

Yes, I got everything including the proportioning valve.

Yes, they were rebuilt and I double checked them. Not pulling, just not stopping.

I've bled the fronts (and rears) till I was blue in the face, no change.
