Volts started dropping quickly & was soon all the way in red. Barely made it to AutoZone on battery power only. Replaced alternator and headed down the road again. Same thing happened again within a few minutes. Barely made to next town. Replaced alternator again thinking maybe 1st one was bad. Samething happened again. AutoZone bench tested both alt's out of car and both read fine and at 13.8. But once put in the car, volt meter check shows a voltage regulator failure. And while in car, alt & battery read lower at 11.8. Thought maybe something was wrong with wiring so tried to bypass communication from alt to computer. Still same issues.
