Rant: A 2017 Ford Escape with a weird electrical drain that took three days to find
Customer complaint was a dead battery every morning. Hooked up the ammeter, saw a 0.3 amp draw, which is too high. Started pulling fuses one by one, but the draw never dropped. Turned out the problem was a bad control module for the power liftgate. It was staying awake and talking to the network even with the car off. The module itself wasn't on a fuse we could pull easily, so we had to trace the wiring diagram. Has anyone else run into a parasitic drain that didn't show up on the fuse box check?
