Question Battery not charging, no output from Alternator

Hey everyone,

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!

Overview:

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!

Same exact thing happened to me, I would bet my life that there is a fuse under the hood in the box, I think its number 14 that blew. Same exact thing happened check that fuse first.

I tested that fuse using my meter and it tested good. I was hoping that was the problem after doing some searches on this site... Thanks for the thought!



Any other thoughts?

There is the order at which the wires are hooked up to the alternator given on ehow.com it says that you have to install the wires to the alternator in the opposite order than the order that they were removed. Maybe that can help. Just had alternator replaced two weeks ago and have not had further problems.

The order in which things are hooked is irrelevant. The thing is off and doing nothing. Pretty sure since this a year old, it has been fixed.
