Glad I found this site. I just got a 2000 Ford Ranger XLT 4.0 that has a charging issue. The local Ford dealership said that the alternator needed to be replaced when I bought it. The truck has a new battery. I went ahead and replaced the alternator, started the truck, and no charge. The gauge in the dash is at the low end of the white zone and the battery light is on. Battery is reading about 11.2 volts, no output on the alternator. Threw on my Optima Yellow Top battery and ran it into the local parts store. They test the alternator (with a meter on the large cable) and verify no output. They order me a replacement and I swap it out the next day. Same problem, gauge is reading low and the battery light is on. I have tested the 30A fuse for the voltage regulator in the engine bay fuse box, it tests good. Battery connections are clean and the cables look good until they enter the split loom tubing. Any help would be appreciated!
New battery installed, when charged reads about 12.8 volts. No drain on battery as far as I can tell as battery will read the same a day later.
2 new alternators installed, not reading output (so alternator is not being told to energize?) from either.
Light and gauge both work in dash. Both not saying good things...
Battery still not charging.
Thanks in advance!
