harn ess.
10) F uel Shutoff So lenoid － Located on
the right of the engin e, on the fuel
injection pu mp, th e fuel shu to ff
solenoid shuts off fuel flow to th e
injection pump to stop the engine.
11) Fuel Level Sending Unit
－

Located adjacent
to th e altern ator, attached on the wire
harn ess.
14) C oolant Temperature Sending U nit －
Lo cated on the front left sid e of the
eng in e cy linder head in the thermostat
housing, the coolan t temperature
sending un it sends a signal ind icating
coo lan t temperature to the temperature
gauge, locat ed on the instrumen t panel.
15) R ela y for HST Brake Switch
－
Lo cated on the bo tto m of steering
column and connected w ith blue
connecto r. The relay utilized by
individual HST cruise contro l sy stem.
Th e cru ise magnet is un -energized when
the both brake ped als are depressed.
16) E ngine Oil Pressure Sw itch － Located
on th e front of the eng in e cy linder h ead.
Th e eng in e oil pressure sw itch closes
when engin e oil pressure is less than
29 .4 k Pa (0.3 kgf/c
㎡
). When th e
switch closes, an ind icator on the
instrument pan el illuminates and
alerting the operato r of low o il
pressure.
