Solution

1. Preparation

Gather tools and ensure safety equipment is available.
Disconnect the negative battery cable to prevent electrical shorts.

2. Battery Replacement (if battery is found faulty)

Tools Required: Wrench set, battery terminal cleaner, safety gloves
Remove the negative (black) and positive (red) battery cables using a wrench.
Lift out the old battery carefully, noting its orientation.
Clean the battery tray and terminals with a terminal cleaner.
Place the new battery in the tray, ensuring proper alignment.
Reconnect the positive cable first, followed by the negative cable.

3. Starter Motor Replacement (if starter is faulty)

Tools Required: Socket set, torque wrench, screwdrivers, safety gloves
Disconnect the battery negative terminal again if not already done.
Remove any components obstructing access to the starter (e.g., air intake duct).
Unplug the wiring harness connected to the starter.
Remove the mounting bolts securing the starter motor using a socket set.
Carefully extract the starter from its position.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
Torque starter bolts to the manufacturer-specified value (usually around 15-25 ft-lbs).
