Fuses and Relays


CAUTION
Never replace a fuse with one having a higher rating or with material other than a fuse because serious damage or a fire could result.
The fuses are designed to melt during an overload to prevent damage to the wiring harness and electrical equipment. The fuses are located in two fuse boxes.
