Shut off the engine and disconnect the batteries before
checking the electrical system fuses or relays.

2. If the vehicle has dual batteries, disconnect both
negative battery cables (7 and 8) from both
batteries.
To access the lower battery (9), loosen the knob (10)
far enough so that the lip (11) on the upper battery
box clears the knob. Lift up the upper battery box (12)
and swing it out, so that the box clears the hydraulic
tank support bracket, to gain access to the lower
negative battery cable (7). Disconnect the lower
negative battery cable.
3. Remove a suspect fuse (Refer to Section 9.7.2,
“Fuse and Relay Locations,” for locations of fuses
and relays) from the fuse and relay panel by pulling
the fuse or relay straight out and away. ALWAYS
install the correct amp rated fuse or relay.
