Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Battery Inspection and Replacement

Tools Required: Multimeter, socket set, wire brush, safety gloves
Disconnect the negative terminal of the battery.
Remove the battery from the vehicle if it is determined to be faulty (use a socket set to remove hold-down bolts).
Clean the battery terminals with a wire brush to remove corrosion.
Replace the battery with a new, fully charged one of the correct specification (usually H6 or similar).
Reconnect the battery, starting with the positive terminal followed by the negative terminal.
Torque the battery hold-down bolts to the manufacturer's specification (typically around 10-15 Nm).

3. Starter Motor Inspection

Tools Required: Socket set, torque wrench
If the battery is functional, ensure the starter motor connections are secure.
Inspect the starter motor for any signs of damage or wear.
If necessary, remove the starter motor (usually requires removal of electrical connections and mounting bolts).
Inspect the motor's gear for engagement issues and check for any debris.
If faulty, replace the starter motor with a new unit, ensuring proper torque on mounting bolts.

4. Testing the Electrical System

Reconnect any components that were disconnected during inspection.
Ensure all fuses related to the starting system are replaced if necessary.
Reconnect the battery and perform a final check on connections and components.
