FUSE PRECAUTIONS



WARNING   WARNING:  Always disconnect the battery before servicing high current fuses.
WARNING   WARNING:  To reduce risk of electrical shock, always replace the cover to the power distribution box before reconnecting the battery or refilling fluid reservoirs.
WARNING   WARNING:  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.
