I changed the alt, compressor, and P/S belt which solved my problem of the car squealing. Drove the car around and the next morning the car was giving me a hard start. I checked the battery it was at 11.91 Volts, I took it to AutoZone to have it charged and it came out too 13.00 Volts 100% charge. I matched up all the belts before putting them on and they where the same but what did change was the alternator's position. I had to screw the alternator tensioner an inch closer to the engine block. Could this have been what caused the battery to drain?
