    On several gm vehicles if you just trick the light sensor to keep the lights on all the time it'll keep you above 14.0v and wont throw a charging system error code, which some vehicles do if you bypass pcm regulation.
    im not saying.that the pulley doesnt need.to be changed im saying.he will still have the pcm symptoms once he gets it straigtened out

    i don't think anyone is arguing that pcm regulation type symptoms wont occur.

    I think we're all on the same page though, now.

    Re: Battery - Alternator HELP

    but then again if the batt light is still on and the pcm senses a charging problem it might not shut the alt down..this might work in your favor

    like i said if u get the batt light off u might drop down to 13 while driving like its suppose to do...if it stays at 14.7 after driving a while i would leave it alone ...u might have tricked the computer to keep the alt fully charging

    you can probably pull the neg battery terminal for 15 minutes or so to reset the computer to have it go away. it's probably just a cel that needs to clear.

    Edit: you could just wait a day or so of driving it and wait for it to go away. if its charging good now i wouldn't be too concerne.d

    voltage stayed fine whole drive home around 14.7-14.9, half hour drive, stopped at harveys and it dropped to 14.5 lowest while in drive through so all seems to be fine, sounds normal and everything except if i accelerate really fast 3000+rpm it makes like a VRR and i feel a TINY vibration in the peddle, im not sure if this is normal, it may be with h.o alts.
    anyways i unplugged my neg terminal and am eating my harveys, i will plug it back in in like a half hour and see what happens.

    thanks both of yas much appreciated

    p.s my buddy got the belt, it wasnt made for my car, but same amount of ribs, and the guy told him it was just shy of an inch shorter, ( although they kkinda looked the same matched up) either way it fixed my voltage issue.
