Charging issues on a ‘64 Valiant...

I knew the electronic ones worked differently, but I didn’t understand how. What I called a “1 wire fleet bypass” was the wrong terminology. I upgraded to heavier gauge wires, used a grommet, added fusible links, and removed the ammeter. My alternator seems to be converted to 1 field by removing the (insulated washer?) and clipping the spade connector. Am I correct when assuming I can reverse this by adding an insulator washer?
Thanks for the knowledge!

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
