So for the last few weeks, I've been having to drive my xj everywhere, because my daily driver also broke down, and I haven't had time to fix it. So today on my way to work, the alternator stopped charging the battery, and I only barely made it to work before it quit.
So I replaced the Alternator, since this one was pretty old and crusty. Even with a new one the thing still wasn't charging, so I started checking fuses, and found that my 60A Alt1 fuse under the hood was popped. Replaced this fuse, and checked with the mulimeter, and got 13v! Within a few miles, however, the idiot light came on again, and checking with the voltmeter showed 10v. Dangit.
So I limped it home, and stuck another fuse in, and with the voltmeter on the battery, wached my voltage as I gradually increased the engine RPM. It went up to 13.5v, then I increased the RPM a little more, and POOF! Big orange flash, and the fuse blew, but also made quite a big flame!
This time it melted the crap out of the fuse, and crustied up the box pretty badly.
I've checked wires coming from the battery and alternator, and grounds going from the battery to the body and engine block, and all are nice and clean, as are my battery terminals.
Anybody have any idea what to check next? I would have expected a large voltage spike as the fuse blew, but never got it.
Please help, my only transportation is my motorcycle now...
