1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe location with the ignition off.
Disconnect the battery to avoid electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion using a wire brush and a mixture of baking soda and water.
- Tighten any loose connections.
Test Battery Voltage:
- If voltage is below 12.4 volts, consider charging or replacing the battery.
- If the battery is faulty, remove it by unscrewing the battery hold-down bracket and disconnecting the negative (-) terminal first, followed by the positive (+) terminal.
Install New Battery (if required):
- Place the new battery in the tray and connect the positive (+) terminal first, followed by the negative (-) terminal.
- Secure the battery with the hold-down bracket.

3. Starter Motor Inspection

Access Starter Motor:
- Depending on the model, you may need to lift the vehicle and remove any covering that obstructs access to the starter.
Check Connections:
- Ensure all electrical connections to the starter motor are secure and free of corrosion.
Test Starter Motor:
- Use a multimeter to check for voltage at the starter terminal while someone turns the key to the start position. If voltage is present and the starter does not engage, replace the starter.

4. Reassemble and Test

Reconnect any components removed for access.
Reconnect the battery and ensure all connections are tight.
Attempt to start the vehicle.
