Tools that may help
Fuse assortment kit
Spare blade fuses in common ratings, so you can swap a blown one at the roadside.
Fuse puller
Grips small fuses without damaging them. Many fuse boxes have one clipped inside the lid.
Digital multimeter
Confirms whether a fuse or socket actually has power, instead of guessing.
