Parasitic Battery Drain
Just a post to help with possible Parasitic Drain issues. We had it on our 2014 F-150 FX2. originally needed to replace the alternator when it first happened. after that we would still get intermittent battery drains. usually would take about 2 days. AFter 4 trips back to Dealer trying to figure it out, along with me trying to diagnose, Finally got it fixed. Turned out to be a bad park/shift switch. it would occationally open the circuit and turn on the computers and cause a 2+ amp draw. couldnt figure out when, other than it was sometime overnight or after a few hours after Sleep mode. Took and accidental look at the dash when the vehicle was supposed to be asleep.
So add that to possible problems to look at when trying to track down this problem
