I have a 2017 transit connect that has had a battery drain issue. Wondering if anyone knows how much voltage fall off should be expected in a 24 hour period? Ford changed key fob program in onboard computer, and that helped quite a bit. Still has about 1 volt drain in 24 hours parked. Nothing left on or plugged in. Battery was going dead in 48 hours being parked before Ford program fix. What is still consuming power when parked?
