Fuse allocation
The electrical circuits of the wheel loader are fused to pre-
vent damage from short circuits and malfunctions. The fuses
are located in box 1 and 2 near the starting key receptacle
on the right side of the steering column. The second location
box 3 is on the right hand side of the cab next to the wiper
and light control switches.
NOTICE:
If an electrical device fails to respond to a control
movement, stop the wheel loader as if stopping at
the end of a work shift and check the fuse for that
circuit. If the fuse has failed, determine the cause
of failure and repair the cause.
Insert a new fuse of the specied rating and return
to work.
Do not continue work with a failed fuse.
Do not install a fuse with a higher rated capacity
than the failed fuse. This can result in serious dam-
age to the electrical circuit.
