Change the fuses
NOTICE
• Be sure to set the engine key switch to the OFF
position before replacing the fuses.
• Do not use wires, silver foils, etc. instead of
fuses.
If such materials are used, the wires may
overheat and burn, resulting in a fire.
• If lamps fail to go on or devices in the electric
system fail to work, the fuses may have been
blown out. Check the fuses and replace a
blown fuse with a fuse of the same capacity.
• If a new fuse still blows out after replacement,
ask IHI’s sales service dealer for checks.
1. Unlatch and detach the fuse cover (1).
2. Replace the blown fuse with a new fuse of the same
capacity.

Change the fusible link
If power is not turned on even though the engine key
switch is set to the ON position, the fusible link (2)
between the battery and the engine key switch circuit may
have blown out. Detach and check the fusible link.
Replace it with a new fusible link, if it has blown out.
