1 wire alternator confusion

Posted by humanpotatohybrid On 2022/12/8 8:42:14
I have a Delco Remy "1 wire" alternator on my car with 2 spade connectors in the back that I think are unlabeled. I have a couple questions:

- Do these even charge at idle? Do you have to rev the engine a bit to get them going, or do they never charge at idle?

- I have read that the #1 terminal goes to a charging light connected to ignition, other times I've read that it goes straight to ignition to power the field windings. Is there a way to tell which is correct?

- Likewise for the #2 terminal, some say to jump it to the output for voltage sensing, others say it's redundant. Does it matter?

This is the only pic I have right now.
