2. STARTING SYSTEM
When the main switch is turned to the PREHEAT position, the terminal B is connected to the terminals G and ACC.
The glow plugs become red-hot, and the preheat indicator lamp also lights on while preheating.
When the main switch is then turned to the START position with the safety switches on, the terminal B is connected
to the terminals ST and ACC. 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 ACC,
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.
