Default Re: ALT Fuse

You ought to see what happens to a buss wire from a 70-amp alternator when it shorts to ground. This was an 8-gauge wire on a 24-volt helicopter. The wire shorted to ground and burned withing 3 seconds. The whole wire from the alternator to the instrument panel went up. It ruined every wire that was bundled close to is as well. This stuff rarely happens but in this case the helicopter was dated to the early 70s, had spent most of its existence out in the open, and it had an antiquated type of wire that has been obsolete for many years. It was in fact the same type of wire that brought a 747 down due to a short inside the center fuel tank some time ago.

I don't much care for fusible links either but they were used by manufacturers for some time. Ford didn't start using them till the 60s.
