2007 Navigator Battery Drain - Ford Forums

beckmagic · 07-13-2009, 07:15

Its now happened 3 times in 3 weeks, something in the electrical system is draining my battery and can't get the car to start. Dealer did full diagnostics and can't find anything wrong. The only thing screwy was about a week before it happened the first time, my radio kept switching between the am band and the dvd player.

Any direction here would be appreciated!

Check for a draw. This will only work if there is a draw when you perform the test.
