10.5 FUSES AND RELAYS
Fuses and relays help to protect the electrical system. In
general, a blown fuse is a symptom of another electrical
problem. Address the true problem, not just the symp-
tom. Simply replacing the fuse often will not solve the
problem. Blown fuses are usually due to simple causes,
including loose or corroded connections, or a defective
relay. There are two main causes of blown fuses; a
shorted or grounded wire in the applicable circuit, or a
defective electrical component. Visually check the condi-
tion of the fuse, wires, connections and components in
the involved circuit before replacing a fuse. Check the cir-
cuit for shorts, grounding, or defective electrical compo-
nents. Keep in mind that many parts in the electrical
system work with components of the hydraulic system; a
careful inspection of the related hydraulic components
may help in solving problems.
For access to the fuse and relay panel, remove the four
screws securing the lower dash panel (Fig. 10– 21) to the
cab. The fuses and relays are mounted under the lower
left side of the operators console (Fig. 10– 22).
The fuse and relay panels are part of the cab harness.
Check illustrations Fig. 10– 24 (S/N 8249 and before),
Fig. 10– 26 (S/N 8250-9398), and Fig. 10– 27 (S/N 9399
and after) on the following pages to determine which type
of fuse and relay panel is being addressed.
Figure 10– 21. Remove the lower dash panel to gain access
to the electrical fuse and relay panel.
Figure 10– 22. The fuse and relay panel is mounted under
the lower left side of the operators console
behind the lower dash panel (typical).
