Failure Symptoms

The primary symptom is the engine failing to crank when the key is turned, or an intermittent inability to start. If left unaddressed, the equipment will become inoperable, preventing any engine operation. This poses a risk of delaying critical work or leaving the machine stranded.

Installation Tip

Always disconnect the battery before removing the old switch to prevent accidental shorts. Ensure the wiring harness connectors are clean and securely attached to the new switch terminals.

Service Note

Inspect the starter motor solenoid and battery connections for any signs of wear or corrosion when replacing the starter switch.
