Can a bad AC compressor cause charging issues??????


Nov 23, 2014
Hello wondering if anyone has had this issue? I'm having charging issues with my alternator. Is it possible for my ac compressor pulley to drag because of a possible short in the ac clutch. which then would make my belt drag and not let my alternator charge correctly??

What I do see is when the A.C. is in the off position the front of the clutch still slightly spins and when I see that my alternator coincidently drops volts to around 10.5 to 11v. When put the ac in the on position the clutch engages and spins faster? Once I get on the gas the car starts charging up near 14v but when I come back to idle it drops back down around 11v.

Any ideas or opinions are greatly appreciated. TIA
