Solution

1. Preparation

Gather tools: battery terminal cleaner, multimeter, socket set, wrench set, and a battery load tester.
Ensure the vehicle is in a safe location and the ignition is off.

2. Battery Service

Disconnect Battery:
- Use a wrench to loosen the negative (-) terminal first, then the positive (+) terminal.
- Safety Warning: Always disconnect the negative terminal first to prevent short circuits.
Clean Battery Terminals:
- Use a battery terminal cleaner or a wire brush to remove corrosion from the terminals and cable ends.
- Reconnect the cleaned terminals, starting with the positive (+) terminal followed by the negative (-).

3. Battery Replacement (if necessary)

Remove Old Battery:
- Unbolt the battery hold-down bracket using a socket set.
- Carefully lift out the old battery (ensure to wear gloves).
Install New Battery:
- Place the new battery in the tray and secure it with the hold-down bracket.
- Connect the positive (+) terminal first, followed by the negative (-) terminal.

4. Starter Motor Check

Locate the Starter Motor: Refer to the vehicle manual for the exact location.
Inspect and Test Connections:
- Ensure that all wires connected to the starter motor are secure and free of corrosion.
Test the Starter Motor:
- If the battery is good and connections are secure, test the starter motor by applying direct power from the battery. If it does not engage, replace the starter motor.
