Battery dies but alternator tested OK?

[jumpsoffrock]

Basically I didn't know that my new alternator was internally regulated and my wiring was wrong. I--on a whim--decided to mock up my wiring "as-if" I had an internally regulated alt only because I had ran out of ideas and research was sending my in circles.

That solved my problem. I have bypassed the external reg and now everything works like a charm.

Here was the flaw in my hypothesis: All 1 wire alts are internally regulated; all 3 wire alts are externally regulated.

I'm not sure where I surmised this from, but that INCORRECT statement is what was making my electrical system not work....not the actual parts themselves.

Funny/stupid lessons to be learned.


Thank you to everyone who chipped in!
