lows.1. Turn the key to “ OFF” and turn off
all electrical circuits.
2. Disconnect the battery coupler.
3. Remove the blown fuse, and then install a new fuse of the specified
amperage. WARNING! Do not
use a fuse of a higher amperage
rating than recommended to avoid causing extensive dam-
age to the electrical system and
possibly a fire.
