Understanding the Role of the 6G74 Starter Motor
The 6G74 engine, one of the common variants in the Mitsubishi Pajero, relies on a specialized starter motor to meet its performance demands. When you turn the ignition key or press the start button, the starter motor is activated, engaging with the engine’s flywheel to crank the engine and initiate the combustion process.
Key components of the starter motor include the solenoid, armature, field windings, and brushes. The solenoid acts as a relay, transmitting electrical current from the battery to the starter motor. The armature, a rotating coil, works in tandem with the field windings to create the necessary torque to turn the engine. Brushes maintain electrical contact with the rotating parts, ensuring consistent power flow.
Given its crucial role, the 6G74 starter motor must be in top condition to ensure your Pajero starts reliably. A malfunction in any of these components can result in beginning issues. For example, a worn-out solenoid might fail to relay current effectively, while damaged brushes could lead to inconsistent power delivery. Understanding these components helps diagnose and address problems with your Pajero’s starter motor.
Common Symptoms of a Faulty Starter Motor
Recognizing the signs early when dealing with a malfunctioning Mitsubishi Starter Motor can prevent more severe issues. Here are some typical symptoms that could indicate your starter motor is failing:
Clicking Noise:
When you turn the ignition key, hearing a rapid clicking sound usually means the starter motor isn’t getting enough power or struggling to engage correctly.

If there’s no sound at all when you try to start the vehicle, it often points to a completely non-functional starter motor. This could be due to a dead battery, but it might also indicate a severe problem with the starter.
Intermittent Starting:
Inconsistent starting performance—where your Pajero starts without issue sometimes but not others—can be a sign that the starter motor is nearing the end of its lifespan.
Unusual Noises:
Grinding noises when starting the engine could indicate that the starter motor’s gears are worn out or not engaging correctly with the engine’s flywheel.
Smoke or Burning Smell:
Any visible smoke or the scent of burning coming from under the hood when you try to start the car suggests a significant electrical issue with the starter motor, such as overheating or a short circuit.
Dimming Lights:
If your dashboard lights dim significantly when you attempt to start the engine, it could indicate that the starter motor is drawing excessive current, signalling an underlying issue.
Diagnosing Starter Motor Problems in Your Pajero
Diagnosing issues with the Mitsubishi Starter Motor involves a systematic approach. Begin by ensuring the battery is fully charged since a weak or dead battery is often the most common reason for starting problems.
Next, inspect the wiring and connections, especially at the battery terminals and starter motor. Corrosion, loose wires, or faulty connections can impede the starter motor from receiving adequate power. Clean and tighten any corroded or loose terminals.
After checking the wiring, move on to the ignition switch. If the ignition switch is faulty, it may not send power to the starter motor, causing starting issues. Testing the ignition switch with a multimeter can help determine if it’s functioning correctly.
Another component to check is the starter relay. A malfunctioning relay can disrupt the flow of electricity to the starter motor. Use a multimeter to test for continuity in the relay and replace it if necessary.
Finally, if all other components are in working order, consider conducting a bench test on the starter motor. Remove the starter motor from the vehicle and connect it directly to a fully charged battery. Observe its operation to see if it functions correctly outside of the car.
By methodically following these steps, you can pinpoint the issue with your Mitsubishi Starter Motor and take the necessary actions to resolve it.
