Alternator AC DELCO or OEM Mazda

Put an AC Delco alternator on my Celica because I couldn't get a Denso for it. Wasn't going to buy a store brand reman that'll die in 6 months.

If it was me, I’d go with the ACDelco. Never had any issues with them so far. Checking for the best warranty is something else you might consider, just make sure to read that fine print closely.

Always buy ac delco OEM alternators not part store crap.

But its a Ford truck/suv and the alternators ALWAYS go bad on them. Word to the wise, buy an AC Delco replacement or Ford OEM, anything else will just die again-they always do.

Another good way to tell your alternator is going is the battery light illumination. I noticed as I drove to higher RPM's, used the vents or even used windows with more power gave more illumination of the battery light. Tested the alternator at a shop and found it to be weak, battery was fine.
