My son has a 94 Ranger 3.0 V-6. The other night, it died. The obvious cause was a dead alternator. We replaced it, and it still wouldn't charge - fried the diodes in the new one, even with a fully charged battery. Replaced the alternator harness and instrument cluster, and it still fries the diodes in just seconds. We did find a short in the tail light harness, but I wouldn't think that would kill an alternator that quickly. We have new alternator #4, and I'm afraid to put it in, as the parts store won't replace it again. The truck will run and drive fine with the dead alternator and a charged battery - everything works. All the connections test as they should. I suspected a major short, but we keep coming up empty-handed. Any ideas? My next guess is to replace the Power Distribution Box and the Fuse Panel.
