Battery problems of the 2004 Ford F-150

The vehicle wrench light came on and the engine quit. Had I been on a freeway, a serious accident might have occurred. I called the warranty service for a wrecker as it was still in warranty. About 40 minutes later, the wrecker arrived and the driver asked me if I had tried to restart the engine. I hadn't, tried, and it started. I researched the internet and found some information including a suggestion to disconnect the battery to reset the computer. Unfortunately, I did that and when I took it to the dealer the following Tuesday they couldn't tell what caused the problem. It happened again on March 25, 2009. Again, I was glad I was on a side street. I will take the truck to the dealer Tuesday even though the warranty has expired as this could be a very serious problem on a highway.

My battery light came on the dashboard came on, after a few minutes it went off, a couple of miles later it came back on, then off again. I checked my voltage gauge and it was fine. A couple of miles later I noticed my lights were dimming, I checked my voltage gauge again and it was reading zero. Minutes later all my electronics went out, no headlights, taillights, brake lights, my speedometer went out and everything else on the dash. Then the engine started misfiring and the vehicle shut off. This all happened while I was driving. I lost my power brakes, my power steering and had no lights. I noticed that while I was waiting for a tow truck, me head lights and tail lights were stuck on. They were on only enough to see the element in the light bulb glowing. The key was out of the ignition and the light switch was in the off position. They stayed on for the entire time I was with the vehicle, which was over an hour. The dealership said all they did was charge the battery and found nothing wrong. What caused the battery to lose a charge? they (Ford) could not answer that question and sent me on my way!.
