My ford explorer 2003 xlt 4 wheel drive electrical system shut down while driving. First battery light come up then headlights turn off and i start to lose acceleration then it just completely died on me. Mechanic says you have bad alternator. This happen to me one time. Truck has a new battery and it has been driving fine without any problem. I have 85000 miles on the Truck.

change your battery cables and check all wires on the alternator for loose connections, expecially the grounds.

I had same problem on my 2002 explorer. Its either the computer module, or the electric solenoid on the transfer case. In my case it was both. The computer module I had done twice in 14 months.

I would check my wiring harness for faulty connections and possibly burnt wires. Also trace the wires from your alternator to the battery. check them over. The battery may need to be replaced. If you let it run down alot and kept jumping it.

solenoid switch that engages the 4WD more likely will need replacing. fairly cheap to fix replace.

The battery light comes on in my truck, and the volt meter reads near 0/low. I have installed a new battery and a new alternator. The same results are shown, What could be the problem? Help!
