Charging issues on a ‘64 Valiant...

NO. READ my posts. READ what I posted earlier. YOU MUST have the proper alternator. POST a PHOTO of the ALTERNATOR you have now. "It might be" that it is one that can be converted due to it's construction and due to the act of some rebuilder before you.

You are not the first to have gone through this. Some of us on here know what we are talking about

POST a photo of YOUR alternator so that the field terminals are clearly visible

This is my exact alternator. I have read what you wrote. You answered many of my questions. I understand I need 2 fields for the electronic one to work.
