Solution

1. Preparation

Gather tools and parts required for repair.
Disconnect the negative battery terminal to prevent any electrical short.

2. Battery Replacement (if necessary)

Remove the negative terminal from the battery followed by the positive terminal.
Unscrew and remove the battery hold-down bracket.
Carefully lift out the old battery and place it in a safe location.
Install the new battery in reverse order, securing it with the hold-down bracket.
Reconnect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection/Replacement (if necessary)

Locate the starter motor, typically found near the transmission bell housing.
Disconnect the wiring harness from the starter motor.
Remove the mounting bolts securing the starter motor to the engine.
Carefully pull the starter motor out and inspect for damages.
If replacing, install the new starter motor and secure it with the mounting bolts.
Reconnect the wiring harness to the starter motor.

4. Cleaning Battery Terminals (if corroded)

If terminals show signs of corrosion, prepare a solution of baking soda and water.
Disconnect the battery terminals as described in the preparation step.
Scrub the terminals and cable connectors with the baking soda solution using a wire brush.
Rinse with clean water and dry thoroughly before reconnecting.
