When cables are put back on battery it is sparking

Asked by Guru5DRFX Dec 22, 2017 at 06:23 PM about the 2007 GMC Sierra 1500 SL Crew Cab SB

Question type: Maintenance & Repair

1 Answer

That means there is a draw on the battery. I would measure how much of a draw to see if it is excessive. As far as I know modern cars should draw less than 100 milliamps normally.
