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!
