In my effort to trace down a starting problem on my ‘55 Nomad, I noticed that a red wire was not connected to one of the spades going to the battery terminal side of the switch. I looked at a wiring diagram to see if a red and black wire were connected there, and apparently both are supposed to be there. The wiring harness is new. I was advised by one member, who has been extremely helpful, that on the new harnesses that red wire would not be connected if the engine was still running points and condenser. It would be connected if an HEI was installed. If it is suppose to be connected, and it’s not, what would be some of the problems I would have? My question is, should I connect it , or not? Any helpful information or advice would be greatly appreciated. Thank you.
