Location Of Fuses<br />
Fuses are located inside the cab, left side, next to the driver’s<br />
door.<br />
Fuse Replacement<br />
CAUTION: Before replacing a fuse, turn OFF all<br />
lights and accessories and remove the ignition<br />
key to avoid damaging the electrical system.<br />
• Be sure to replace a blown fuse with a fuse of the correct<br />
rating.<br />
• If a fuse blows repeatedly, do not keep on replacing it.<br />
The cause of the short circuit or overload must be found<br />
and eliminated.<br />
CAUTION: Never patch fuses with tin foil or wire.<br />
This may cause serious damage elsewhere in<br />
the electrical circuit, and it may cause a fire.<br />
See the Medium Duty Maintenance Manual for instructions<br />
on fuse replacement.<br />

For proper electrical system performance, refer to a wiring<br />
diagram for your chassis before adding electrical options.<br />
