I'll be sure to check that when I get the engine started up.

I got all the connections corrected and went to give her a start and the battery is dead/weak. So I put the charger on it and will go back out later.

In my original post I mentioned that I had corrected the ignition wiring for the distributor. I still had the old resistor-wire battery lead left over so I went to cut the spade off and cap it. I noticed there's a red wire and purple-orange wire jammed into it. I thought at first me having cut these apart was causing the low-volt start, but joining them together doesn't change anything. The charger is showing good draw so it does look like the battery drained for some reason.

Just by the colors of those wires anyone have a theory on what they are? It looks like they both run up the harness to the firewall connector.
