3.2.13 FUSE
IMPORTANT
• Before replacing a fuse, be sure to turn off the starting
switch.
The fuses protect the electrical equipment and wiring from
burning out.
If the fuse becomes corroded, or white powder can be seen, or
the fuse is loose in the fuse holder, replace the fuse.
Replace the fuse with another of the same capacity.
Fuse Capacities and Circuit Names
3.2.14 BLOCK FUSE
If the starting motor does not turn even when the starting
switch is turned to the ON position, block fuse (1) is probably
blown, so open the cover at the right side of the machine and
check or replace the fuse.
This is at the top surface of the battery.
For details of the method of opening and closing the cover on
the right side of the machine, see "3.2.10 COOLING COVER".
NOTE
• A block fuse is a large fuse wire installed to the circuit where
a large-capacity current is flowing. It acts in the same way
as a normal fuse to protect the electrical equipment and wir-
ing from burning out under abnormal current.
No.
