I replaced the alternator and starter on my 1997 4.2 F150. It worked fine for a couple of weeks. The battery light came on intermittently today. (It quit coming on while voltage dropped) the light is not on anymore. The voltage dropped on the cluster gauge. I am getting 14 volts out of the alternator but it is not making it to the battery. The mega fuse is okay. I also have a new wiring harness from the battery to the starter. Any thoughts????
