Yes, That red wire definitely needs to be connected to the ignition switch, on the spade terminal right next to the one with the black wire. It provides the +12VDC power to a lot of things in your car's electrical system, and it is an integral part of the battery charging path. The red wire has NOTHING to do with an HEI installation.

The upper pic is the back of the switch with a heavy red wire already connected by the black wire at the BAT terminal. That's the first pic he sent me before discovering the other wire not connected. the lower pic is a loose wire that was just dangling in there. There's not another terminal left on that switch for that extra red wire.
I did not know that by simply looking at the photos. How did you determine that the loose wire was for an HEI? Could it also possibly be for either the cigarette lighter, or have fallen off of the headlight switch?

The red wire does not have anything to do with the starter. It is the black wire on the ignition switch that is the source of +12VDC for the starter solenoid through the ignition switch (purple "SOL" wire). It also provides +12VDC to the red wire on the ignition switch to power most everything else electrical on the car. As Kenton said, "Make sure the red wire is a good tight fit on the ignition switch spade terminal". By replacing the red wire on the ignition switch, your loss of electrical power problem has been corrected. As far as the starter problem, it is still probably either the solenoid/ Bendix on the starter, or the starter motor itself. The only thing inside the car that could cause the starter problem is a loose or defective purple solenoid wire on the ignition switch, or the ignition switch itself being bad/ intermittent.

I lost track. Are your ground cables correct as per OEM? One from the negative battery cable to the firewall, and the other from one of the starter bolts to the firewall? It is of paramount importance that both of the ground cables have a good connection to the firewall. The use of the correct star grounding washers is also very important.

BTW, I really like your Nomad. It is a beauty! Could you post some more photos of it?

I didn't say it was definitely HEI, I said POSSIBLY. He said it had been completely rewired and thought it could be for something like that and wasn't used. I just saw that that red wire was already on the switch and all the terminals are used. He said he found that other red just hanging there.
Understood. I thought that you may have seen or knew something that I missed.

No, as said, it could be cigarette lighter or who knows. Anyone's guess is as good as mine. Distance diagnosis is pretty prohibitive. I am pretty sure if I had it hands on I would figure it out.
I guess that you missed it. In post #8 he confirmed that both of the pictures that he posted were of the same red wire. So, the wire definitely goes to the back of the ignition switch on the "Batt" spade terminal next to the black +12VDC wire.
