When the main switch is turned to the
PREHEAT
position, the terminal
B
is connected to the terminals
19
and
AC
. The glow plugs become red-hot, and at the same time, the glow plug indicator also lights on.
When the main switch is then turned to the
START
position with the safety switches on, the terminal
B
is
connected to the terminal
50
and
AC
. Consequently, battery current flows to the starter motor and start the engine.
The main switch automatically returns to the
ON
position, the terminal
B
is connected only to the terminal
AC
,
thereby causing the starting circuit to be opened, stopping the starter motor.
When the main switch turned from the
ON
position to the
OFF
position, the fuel cut-off solenoid moves the fuel
injection pump control rack to the
"No Fuel Injection"
position and stop the engine.
