The battery in my Expedition has been replaced 3 times in three weeks....after the vehicle sets for a couple days it will not start. The Ford dealership repair shop can not find the problem. I am at a loss what to do next.

THE MOST LIKELY CAUSE IS ELECTRICAL DRAW. REMOVE THE NEG BATTERY CABLE, PUT A TEST LIGHT BETWEEN TH NEG POST AND THE NOW LOSE TERMINAL. IF THE LIGHT ILLUMINATES BRIGHTLY, THERE IS A DRAW. (A SMALL AMOUNT OF LIGHT CAN BE PRESENT FOR FULL-TIME CIRCUITS AND PCM CONSTANT VOLTAGE)
UNPLUG FUSES ONE AT A TIME UNTIL LIGHT GOES OUT. WHEN YOU FIND THE FUSE WITH THE DRAW YOU'LL HAVE TO TRACE WIRES AND/OR
REPLACE THE NESECCARY COMPONENT LINKED TO THAT FUSE.

Thank you so much. I would think the Ford dealership would have done this but it would not surprise me if they didn't. I will find someone to do this test for me and will let you know if it worked.
