1998 Ford Ranger 3.0 liter V6 130,000 miles. Battery light blinks on, lights dim and altmeter goes to discharge above 2500 rpm. Battery terminals have a bit of buildup on them, though they were cleaned and painted 6 mos ago. Suspect alternator diode. Any insight
Thanks

I side with your insight. When yo get an alternater, be wary. I would go top end NAPA or USA brand myself. All alernaters are not equal.
