This same thing happened with the previous alternator. All my lights, inner and outer would glow or dim in and out, before the high voltage started and then my battery died. My lighting is not dimming yet. It seems brighter somewhat. When I put in the new alternator, the lighting stayed constant, and then the high volts started again at 18 volts yesterday. Last two nators are from Kragen/Oreilly. Very hesitant to drive car.

MasterI suspect the quility of the alternators that you have purchaced. The voltage regulator that is intergral with the alternator most likely is causing your problem. Best take it bactk and see if they will exchange it for a better brand. I suggest DENSO as a reliable brand of remaufactured replacement.

PARTS GUY June 13, 2012, 16:45MasterIt has been 7 days since you posted. If you are still driving this car now you will do damage to the PCM(computer). DO NOT DRIVE ANYMORE UNTIL FIXED.
