1. Disconnect the 2P connector from engine stop solenoid. 2. Measure the resistance between the terminal 1, terminal 2 of engine stop solenoid and body. 3. If resistance differs from the factory specification, the coil is faulty.
1. Disconnect the 2P connector from engine stop solenoid. 2. Turn the main switch to “ON” position and set all levers to NEUTRAL position. 3. Measure the voltage between the terminal 1, terminal 2 and chassis. 4. If the voltage differs from the battery, battery, slow blow fuse, safety switches, OPC timer, engine stop relay… Read More »
1. Disconnect the lead from the glow plugs. 2. Measure the resistance between the glow plug terminal and the chassis. 3. If 0 ohm is indicated, the screw at the tip of the glow plug and the housing are short-circuited. 4. If the factory specification is not indicated, the glow plug is faulty.
1. Disconnect the wiring lead (1) from the glow plug (2) after turning the main switch off. 2. Turn the main switch key to the “PREHEAT” position, and measure the voltage between the lead terminal and the chassis. 3. Turn the main switch key to the “START” position, and measure the voltage between… Read More »
1) Connector Voltage 1. Turn the main switch off. 2. Remove the starter relay. 3. Measure the voltage across the terminal C and chassis. 4. Measure the voltage across the terminal A and chassis while turn the main switch to START position. 5. If the voltage is different from the battery voltage, battery, slow blow… Read More »
1. Disconnect the battery negative cable from the battery. 2. Disconnect the battery positive cable and the leads from the starter. 3. Remove the starter from the engine. 4. Disconnect the connecting lead (1) from the starter C terminal (2). 5. Connect a jumper lead from the starter S terminal (3) to the battery positive… Read More »
1. Disconnect the battery negative cable from the battery. 2. Disconnect the battery positive cable and the leads from the starter. 3. Remove the starter from the engine. 4.

1. Measure the voltage across the B terminal and chassis. 2. If the voltage differs from the battery voltage, check the battery’s cable.
1. Disconnect the 2P connector (2). 2. Measure the resistance between connector terminals while pushing the clutch pedal switch. 3. If 0 ohm is not indicated, switch is faulty.
1. Disconnect the 4P connector. 2. Remove the HST neutral switch (1). 3. Push the switch and measure the resistance between terminal 1 and 2, and between terminal 3 and 4. 4. If 0 ohm is not indicated, switch is faulty.
