Asked by Apr 06, 2016 at 02:35 AM about the 2003 Ford Expedition XLT 4WD

Question type: Maintenance & Repair

I have an 06 expedition. While I drive the battery
gauge goes all the up, radio shuts off, odometer
shuts off and the windows don't work. I took it to
the dealership and they said to change the
alternator. I did that and nothing changed. What
should I try next?

The charging system is controlled by the ECM on this rig, it would be best to have the system live data scanned to see if the problem is a computer or a wiring problem. Did the dealership do the work? If so they didn't rerun the tests or they would have caught it before you picked it up.

I didn't have the dealer do the work. They wanted way to much money. I did it myself.should I just atke it in and have them rerun it? Could it be the relay?

You really don't need to take it to a dealer, but do check some of the local shops reviews and pick one to take it too if you don't have one.
