Important: Always disconnect the battery before servicing high-current fuses. To reduce the risk of electrical shock, always replace the cover with the power distribution box before reconnecting the battery or refilling fluid reservoirs. Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire.
