The ignition switch is located in the upper left section of the circuit diagram. This switch receives battery
power through the wiring 3.0W.
1) ACC: When the ignition switch is turned to the 1st stage, ignition switch ON power is supplied through ACC: When the ignition switch is turned to the 1st stage, ignition switch ON power is supplied through ACC: When the ignition switch is turned to the 1st stage, ignition switch ON power is supplied through
the terminal BR2 and wiring 2.0WB. When following the wiring 2.0WB from the terminal BR2 in the
circuit diagram, this wiring is passed through two 20 A fuses and is connected to the combination switch
for input power. Power supplied through the first fuse (No. 06) is delivered to various lamps through the
combination switch. Power supplied through the second fuse (No. 07, 20 A) is delivered to the flasher
unit, turn signal lamps and hazard warning switch through the turn signal lamp switch.
2) ON: When the ignition switch is turned to the 2nd stage, ignition switch ON power is supplied through ON: When the ignition switch is turned to the 2nd stage, ignition switch ON power is supplied through ON: When the ignition switch is turned to the 2nd stage, ignition switch ON power is supplied through
the terminal BR1 and wiring 3.0WR. Firstly, an ignition switch ON signal is delivered to the glow
controller through the 5 A fuse and wiring 0.5RB. The glow controller starts to control preheat operation
as soon as it receives this signal. Secondly, this power is delivered to the terminal IG of the generator
through the 5 A fuse and wiring 0.5RL, passing through the diode. Thirdly, it is connected to the fuel
feed pump through the 5 A fuse and wiring 0.85RG to run the fuel feed pump with the ignition switch
ON. Fourthly, it is connected to the fuel cut-off solenoid through the 10 A fuse and wiring 0.85RY to
supply and cut off fuel depending on the position of the ignition switch (ON/OFF). Fifthly, it is delivered
to the brake lamp switch switch through the 20 A fuse. Sixthly, it is supplied to the PTO selection switch
through the 10 A fuse and wiring 1.25RB. Seventhly, it is connected to the instrument cluster through
the 5 A fuse as main power for the instrument cluster.
3) Manual preheating: When the ignition switch is held in between the ON and START positions, the Manual preheating: When the ignition switch is held in between the ON and START positions, the Manual preheating: When the ignition switch is held in between the ON and START positions, the
manual preheating signal is supplied to the glow controller from the terminal C2 through the wiring 0.85L
to activate manual preheating.
4) START: When the ignition switch is turned to the START position, an engine start signal is supplied from START: When the ignition switch is turned to the START position, an engine start signal is supplied from START: When the ignition switch is turned to the START position, an engine start signal is supplied from
the terminal C1 through the wiring 0.85BW. This start signal is passed through the safety switch and
is delivered to the safe start relay. When the safe start relay receives a PTO engagement signal from
(A), the 5P relay is energized so the relay main power is disconnected. Therefore, the engine cannot
be started when the PTO switch is set in the ON position. When the safety switch is connected and the
PTO switch is in the OFF position, power is supplied to the coil of the start relay so main power of the
start relay is directly supplied to the start motor for cranking.
