FUSE SPECIFICATION CHART

Power Distribution Box

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

Locate the power distribution box in the engine compartment. It has high-current fuses that protect your vehicle’s main electrical systems from overloads.If the battery has been disconnected and reconnected, you will need to reset some features.   See   Changing the 12V Battery.

CHANGING A FUSE

Fuses

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.

If electrical components in the vehicle are not working, a fuse may have blown. Blown fuses are identified by a broken wire within the fuse. Check the appropriate fuses before replacing any electrical components.Fuse Types

Callout	Fuse Type
A	Micro 2
B	Micro 3
C	Maxi
D	Mini
E	M Case
F	J Case
G	J Case Low Profile
