Some stuff you don't really want on fuses. If you look at an everyday production vehicle the primary feeds are protected by self-resetting breakers.

Case in point would be the engine ignition system or the lighting. The light switch power feed will be protected by a 30A breaker the individual outputs will then be fused (5A for dash lights, 10~15A fuse for running/brake lights, NO FUSE for headlights). The stock Cobra electrical system sucks, but that's to be expected from any British car.

Add to that Ford having the worst electrical systems of the US mfgs. and well, there you go...

Ignition, Fans, Charging circuit, and Headlights should only be on breakers. The fuel pump is about the only "critical" circuit I'd consider running a fuse on.
