Asked by Apr 18, 2016 at 10:34 PM about the 1991 Ford Explorer 4 Dr Eddie Bauer SUV

Question type: Maintenance & Repair

I own a 91 Ford explorer.  I bought a new battery
because it was needed. Yesterday when I started it
up to head home it died so I got a jump. Well it
died again. I figured it was the alternator so I got it
tested it was bad so I replaced it. Work for a hour
or to and the battery died. Found out the alternator
isn't charging my battery. I was told when you
disconnect the battery it should stay running but it
dies I have a good battery and a good alternator.  
What you think the problem could be?

Not true on your vehicle, disconnecting a cable on a running engine can cause a voltage spike that can fry electronic systems. Fords have a real problem with charging system wiring, so look for burnt connectors and wiring, and remember an alternator will not last long trying to charge a dead battery.

also, quite often alternators are bad right out of the box. if you buy one have it tested before you leave with it.
