2000 250 Charging Issue
Hello all! I am new to this forum and I am hoping to get some help.
2000 F250 4X4 with the 5.4. I replaced the alternator because I thought it was bad. It was not charging the battery and the gauge on the dash said it was not charging, and when I disconnected the positive battery post the truck died. To me that was meaning a bad alternator.
Put in a new alternater and still nothing. The truck still dies when you disconnect the positive terminal from the battery. What gives? The battery starts the truck on its own, but it is a little weak.
Any help is much appreciated!
Thanks,
Jacob.

Is alternator main output show 14 volts or so? in not I'd start by checking all the fuses in both fuse blocks. I think there is one that feeds voltage back to the alternator in the drivers side box. Turn truck off first.

I believe it also has an inline fuse for the battery wire coming from the alternator, one that is molded into the line closer to where it ties into the positive line from the battery. Also make sure the field wire is okay. If it gets unhooked or broken everything goes downhill quick. And as Howarda said "Turn truck off first."
How old is your battery by the way? You might have a battery getting pretty old and making the alternator work overtime to charge it while running the rest of the truck's electronics.
