A bad voltage regulator will keep a good alternator from charging.
It is on the passenger fender well IIRC. And you can get a cheap one for 12.00. I would recommend the cheap one for test purposes and if it fixes your problem. Go get a motorcraft one at the dealer and put the cheapie in the glove box for a back up, as the motorcraft ones are very good regulators. The aftermarket ones are very cheaply bulit and are regularly poorly adjusted for voltage output and don't last long.
I think FoMoCo ones are around 49.00
