Hey Y'all, outta the blue, the brake and chg light started coming on at idle. If I leave it idling, it will suddenly die. Initially, I could rev it up and it would go out and stay out, staying running until the key was turned off. Repeat that and drive, no probs. Now, it won't stay off after the rev trick, coming back on as soon as it returns to idle. I also need higher revs while driving to keep it off. Load tested the batt and replaced. New battery didn't cure. Alternator I assume? Are the internal voltage regulators adjustable to kick the alt on sooner? Or is it just worn out and ready for replacement. How's the napa rebuild for $40?
