After replacing my radiator one day, i turned the truck on, after it idled for about 1 minute, i saw the fuselink for the alternator start smoking, i shut the truck off. I got my volt meter and tested it; it said it was putting out 16 volts. I took the alternator into o'reillys and autozone, they both said it was Good. The battery i know is good. I believe there might be a short in the harness that comes off of the regulator on the alternator, but i'm not sure. Any ideas as to what may have caused this?
