Circuit Breaker
A main circuit breaker is in the battery box. It will automatically
cut off in case of an electrical short circuit or overload. This will
prevent the electric wiring and components from being burned or
damaged.
If the circuit breaker is cut off, check all related circuits, this
means something is wrong in the electric circuit.
After maintenance, press the red button for normal operation of
circuit breaker.

If the engine does not crank, first check that the starter switch is
turned "ON" and that no power is available (No indicator lights
will light.). Check that the "A" portion (Figure 127) of the fusible
link is not broken or burned through. Replace the fusible link if
damage and investigate cause.
HAAE2120
WARNING!
Figure 127
When changing the fusible link, replace the fusible link with
the same capacity part. Otherwise, a fire could break out in
the wiring harness and/or other components of the circuit.
Always use original DOOSAN parts.
Fuse Boxes
There are two fuse boxes (Figure 128) on the left side of the
heater box. The fuses prevent electrical devices from
overloading or shorting.
A decal attached to the inside of the fuse box access cover
indicates the function and amperage of each fuse.
NOTE:
For a further explanation see “Fuse Boxes” on
page 2-60.
Spare fuses are mounted on the inside of fuse box access
FG000110
cover.
Figure 128
Change a fuse if the element separates. If the element of a new
fuse separates, check the circuit and repair the circuit.
CAUTION!
Always replace fuses with the same type and capacity fuse
that was removed. Otherwise, electrical damage could
result.
