It's a non computer-controlled alternator

Yeah, everything I can find shows this is just a good ol' internally regulated alternator. I'm assuming there's a fused B+ circuit in the same alternator connector, jerry r? As long as that circuit shows battery voltage (or within a tenth or two), then it's time to search for ANOTHER alternator.

If you haven't already, also voltage drop the big B+ cable at the alternator, engine running and loads on. Over .3V drop is suspect.

If it makes you feel better, I went through this last month on a '15 Kia. :silly: Three parts store alternators before I found one that charged at all.
