Solution

1. Preparation

Gather tools: multimeter, socket set, wrench set, battery terminal cleaner.
Ensure the vehicle is in park (automatic) or neutral (manual) with the parking brake engaged.
Disconnect the battery before starting any electrical work.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Remove the negative (-) terminal first, followed by the positive (+).
- Clean terminals and cable ends with a battery terminal cleaner.
- Reconnect terminals securely.
Check Battery Voltage:
- Reconnect the battery and use a multimeter to check voltage.
- If below 12.4 volts, charge the battery or replace if it fails the load test.

3. Starter Motor Replacement (if necessary)

Remove Starter Motor:
- Disconnect the battery again.
- Locate the starter motor (typically near the transmission).
- Remove the bolts securing the starter with a socket set.
- Disconnect the electrical connectors from the starter.
Install New Starter Motor:
- Position the new starter motor in place.
- Reconnect electrical connectors securely.
- Torque the mounting bolts to the manufacturer’s specifications (usually around 30-40 ft-lbs).
Reconnect Battery:
- Reconnect the positive (+) terminal first, followed by the negative (-) terminal.

4. Final Checks

Start the engine to confirm the repair was successful.
Ensure all components are properly secured and functioning.
