FUSIBLE LINK 3
If the starting motor does not turn when the starting switch is
turned to the START position, there is probably a disconnection
in fusible link (1) or (2). Open the battery box cover on the right
side of the chassis, then check and replace the fusible link.
(1): Fusible link for 24V power supply
(2): Fusible link for 24V permanent power supply
Fusible link (2) is taped to the nearby wiring harness. When
carrying out inspection or replacement, check the wiring har-
ness number.
REMARK
A fusible link refers to the large-sized fuse wiring installed in the high current flow portion of the circuit to protect
electrical components and wiring from burning, in the same way as an ordinary fuse.
