What causes an ignition fuse to blow?
The only reason a fuse will “blow” is because of a short circuit. That is a point where a wire connects directly to a ground and more current tries to pass through the wire than it is designed to handle. At that point the fuse will blow to keep the wiring from being damaged.
Can an ignition switch blow a fuse?
