Description
In order to ensure the normal operation of the system, every electrical system is equipped with fuses and relays. The
fuses and relays are stored in the fuse boxes.
The vehicle fuses and relays are located in the following locations:
•Power Fuse Box
• Front Fuse and Relay Box
• Body Fuse and Relay Box
Operation
When replacing a open fuse, it is important to use only a fuse having the correct amperage rating. The use of a fuse
with a rating other than indicated may result in a dangerous electrical system overload. If a properly rated fuse con-
tinues to open, it indicates a problem in the circuit that must be corrected.
Power Fuse Box
Description
The power fuse box is located on the side of the battery. All of the electrical current distributed throughout the vehicle
is directed through the power fuse box. The power fuse box houses five maxi-type bolt in fuses.
Operation
All of the current from the battery and the generator output enters the power fuse box through the cable and eyelet
that are secured with a nut to the power fuse box B(+) terminal stud located on one end of the power fuse box
housing. The power fuse box terminal stud cover is unlatched and opened to access the fuses.
