Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery cover if present.
- Clean any corrosion from battery terminals using a mixture of baking soda and water.
- Tighten the battery terminals securely.
Replace Battery (if necessary):
- Remove the battery hold-down bracket using a socket set.
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the old battery and install the new battery (ensure the same specifications).
- Connect the positive terminal first, then the negative terminal.
- Reattach the battery hold-down bracket and cover.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- Reconnect the negative battery terminal.
- Using a multimeter, check for voltage at the starter when the ignition is turned to the start position.
- If no voltage is present, the ignition switch or relay may be faulty.
Replace Starter Motor (if necessary):
- Disconnect battery again.
- Remove the wiring harness from the starter motor.
- Unbolt the starter motor from the engine block using a socket set.
- Install the new starter motor, ensuring proper alignment.
- Reconnect the wiring harness and battery terminals.
