If this alternator fuse is only 15amps, then it won't disable the main charging wire, because that can be 50-60amps(even higher, i don't know).
So if that's just disabling the yellow/black field exciter wire, then we're back to square 1 of, "the alternator only needs 1 wire to charge".
Or so i'm thinking. I'll have to find the alt fuse and test this theory.

Yeah that certainly does make sense. I'm going to do a few more tests before I give up. Last night out of curiosity I disconnected the 4 pin plug again, made a jumper from the alternator charging control wire to ground, like in my original post on this thread, and it appeared to not be charging at all. With a large electrical load I was seeing 11.x volts, whereas with my original setup it looked to be still charging just at a slow rate. I'm wondering if some combination of this ground and pulling one of the other 3 wires will disable the alternator.
So i'm going to go out and check.
