Thread: Battery Issues

  1. #1

    Question Battery Issues

    I have a '99 GMC Sierra and am experience some Electrical issues. I have went through 3-4 batteries, each only lasting a few weeks before they are shot. Checked the amp draw when turned off and only seeing 1 to 1 1/2 amp. Thought I had a Voltage Regulator issue so changed out the Alternator and replaced battery. Battery won't stay charged for more than a day without running vehicle. Anyone out there have some thoughts or advice?
    Baffled in the Carolina's!

    You have just found your own problem! 1 to 1.5 Amp draw is way too much parasitic draw. You should have no more than 1 or 2 miliamps. Start pulling fuses until you find your problem. I have seen a glove box light which stayed on drive a good man to drink!
