Solution

1. Battery Inspection and Replacement

Check battery terminals: Ensure they are clean and tight. If corroded, clean with a wire brush.
Replace the battery: If the battery is weak or fails the load test, replace it with a new one.

2. Starter Motor Inspection

Remove starter motor: Disconnect the negative battery cable, then remove the starter motor by unbolting it (usually requires a socket set).
Inspect wiring and connections: Check for any signs of wear or damage on the starter wiring. Repair or replace as necessary.

3. Starter Relay and Ignition Switch Check

Replace starter relay: If the relay is faulty, replace it with a new one.
Test ignition switch: If the switch is not functioning properly, it may need to be replaced.
