SOURCE: not charging

Possibly a fusible link somewhere in the circuit has burned through and disconnected the circuit.A wiring diagram would be needed to look for the location of any fusible links Ohms check the wires involved in the alternator charging circuit to verify continuity.

Looking for the fuse that works with alternator.


no standard fuse in a fuse panel some vehicles have a master fuse/link that attaches inline if looking to pull fuse follow battery positive to where it links up with alternator some are by battery some by radiator but if its a fusible link not going to be able to pull it ---and as to a regular fuse their is none and some vehicles dont have any short in alternator usually means no out put if short in wiring than would have a constant drain on battery --their is no fuse that would stop that if short in wiring test the lines and replace the wires their is usually about 10 ft of wiring --if alternator pull connector from it

My 1999 f250 wont charge, to date we have changed and tested the alternator (x4) the battery (x3) the under hood alternator plugs and the battery terminals. tested the wire between the alternator and


Let's start at the beginning.
When you turn the key on, you send 12 volts thru the charge light (if equipped) which triggers the alternator "on" and when the engine starts the alternator should generate enough voltage to reverse the direction of that circuit and turn the light off. If you have a volt gauge the effect is the same without having a warning light.
On some models the alternator gets its on signal from the engine computer instead of the instrument cluster.
If the alternator checks out ok on the test bench, but does not produce 13-14 volts on the truck, either the main power circuit is dead, or the alternator is not getting the "on" signal.
The three circuits involved are the large wire with a 175 amp mega fuse or fuseable link, a 20amp circuit going to the alternator, and a 10amp circuit to power the alternator "on".

I had the same problem on my 96'. It ended up being the mega-fuse, which is located on the left side of the fuse box under a plastic cover that slides up. It has two wires running to it(one of which is the main wire from the alt to the battery), and two bolts holding it in. Hope this helps.
