Battery dies in 2 days Pontiac grand prix alternator check is ok could it be radio or onstar dealer says no pulled all fusese didn't stop draw when car off?

Answer 1

50 MILIAMPS or less is considered o/k for a draw on a system. If you have pulled all the fuses and the battery is still draining down have you considered that the battery might not be holding the charge? What happens if you don'y drive the car for a few day but the battery is unhooked? Alternators have been known to cause intermittant drains on their own. Also radios have been known to cause intermittant drains. Give me some more info, year, mileage, aftermarket options, engine size, symptoms & I'll look for you feedback. Do you have a digital multimeter?
