Inspection, Maintenance and Adjustment
Fuses
1. The fuses in the fuse box are used to protect the various
electrical circuits and their components from being
damaged. See Figure 146. The fuses used are standard
automotive type fuses.
2. The section on “Fuse Identification” on page 4-78, lists the
circuits and the fuse amperage required for each circuit. If
a fuse blows, determine the cause and repair any faults or
failures.
3. Do not insert a higher amperage fuse into a lower
amperage slot. Serious damage to the electrical
components or fire can result.
Fuse Boxes
There are two fuse boxes (Figure 147) 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's cover indicates
the function and amperage of each fuse.
Spare fuses are mounted on the inside of fuse box's cover. (One
each of a 10A, 15A, 20A and 30A.)
Change a fuse if the element separates. If the element of a new
fuse separates, check the circuit and repair the circuit.
