Should have about 14.3 to 14.5 volts. You still have a problem. Bad alternator I would suspect. Screamin Seamin

as far as i recall these are internally regulated so im quessing thats fine but make sure you dont have a draw somwhere that is robbing power from your system(also try all accesories on and lights on bright a\c on high and all that jazz and see if the voltage goes up or down) Holdin M

The problem is a defective alternator, they probably got it from auto zone. Take the car back to Sears and tell them what is going on, I am sure they will resolve the problem at no cost to you. Will S
