Ok I have a 03 Chevy suburban with a parasite draw it drains within a day. I have narrowed it down to the radio (220 ma), IDC (98 ma), amp 120 (ma) on the fuses, I have disconnected each component separately and let sit for a few days. When the radio is unplugged it still draws 90-110 ma. I checked the BCM it's fine, new battery, alt is good, checked grounds, and for skinned wires anywhere in that area back to the dashboard. No OnStar in the vehicle, I have installed an online disconnect on the negative battery cable just in case. I would like to eliminate it so I can sell the vehicle.
