Burnt wires

2004 Tacoma, V6, Auto.
3 wire plug, and 4 inches of the wire, from the back of the alternator burnt.
Looks like a direct short from someplace.
Nothing touching anything.
Not sure what could have caused it.
Any ideas?????

3 Wires????

Does anyone have a wire diagram for the wires going to the alternator????
There are three wires that go to it. I'm looking for what the wires go to, and the pin out reading.

The heavy white wire on the stud is the output and goes to the battery,
The connector has white wire that goes to the battery, a red wire that goes to the IGN switch, and a yellow wire that goes to the Charge light circuit.

Thanks.
I found a wire diagram. Had them saved on the computer.
Got everything back together. All is good.
Still have no idea why the wires burned.
Checked the fuses to see if they were shorted. They were not.
I would have thought the fuse would have poped before the wires burnt.
Replaced the alternator at the same time just incase.

It's simple, wires overheat and burn because too much current is being drawn through them, typically because of a short.
If the circuit is fused and the fuse doesn't blow, it's because the short has occurred between the fuse and the power source (battery).
And you can't check a fuse for a short, because a good fuse IS a short. When it blows it goes open.
