1972 RR 440 won’t start after running fine. Battery and fuses seem good. Replaced alternator, voltage regulator and ballast resistor. Any ideas?

If it was my car, and it isn't, from the hacked wiring I saw in the pictures, I would replace all of the wiring with M&H or Evans. New battery cables of the same. The big black wire on the alternator should have a guard on it.
Again, if it was mine.

I had never noticed that green button before. I’m not sure what it does. Looks like it runs through the firewall near the brake pedal…does it look like speaker wire? I don’t see it coming out in the engine bay.

I know this funky wiring isn’t helping my case but it did run quite well for the past year. Though I’m sure all it takes is something coming loose.

The green button was for the juice.

Yea, lets replace the car to fix a simple start problem. I call that dumb money.

I have the money, dummy.

50+year old wire thats hacked up, I would replace it too, fire waiting to happen.

Mine should’ve burned down 30 years ago. Next time I have a no start, I’ll tear down the whole goddam car like the boys here would want. Jesus Chrysler.
