Q: Parasitic drain 2005 Chevrolet Tahoe

asked by on February 12, 2017

I have an 05 Tahoe that battery dies after 2 days of sitting. Has new battery, starter, and alternator. With a meter reading amps between negative post and cable it gets down to only .620 ma. Only the rear Ac fuse has much affect when pulled. It drops about 25 ma. Everything else drops a few ma here or there. I even pulled every fuse under the hood and under dash and it still read .620. It wasn't until I pulled the 40 amp ignition A fuse the ma went to .035 with or without all the other fuses. I can't find any shorts anywhere. No lights anywhere left on. Remote start power has been disconnected which showed no real drop. Could a faulty ignition or them ecm need to be reflashed because of not putting stuff to sleep? Thanks
