1992 Buick Park Ave. I have replaced the alt 3 times and the batt as well. Both keep dying. The batt is dying cause of the alt, that I know for sure. The wiring is good. The volt gauge shows about 10 to 11 volts when under a load like w/ ac or lights on. The alt works fine for about 2 weeks, and then it starts making a slight noise, and thats when I have volt prob! When I turn on power in the car, e.g. power seat - etc., volt drops! Especially when the lights, or ac is on! It has 127k miles on it, and has been taken care of. The crank sensor is new, there are no codes, plugs, wires are new! No fuses are blowing. I have checked all visible grounds and are good. I know alot about this car from inside to out but this is a challenge that is kickin my butt! Please help!!! Rob
