Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the transmission in 'Park'.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Check Battery Health
- Use a multimeter to confirm voltage. If below 12.4 volts, proceed to charge or replace the battery.
- If using a battery charger, connect it and follow the manufacturer's instructions.
Clean Battery Terminals
- Remove the negative terminal, then the positive terminal.
- Clean the terminals and cable ends with a wire brush and a mixture of baking soda and water to remove corrosion.
- Dry and reattach the positive terminal first, then the negative terminal.
Replace Battery (if necessary)
- If the battery is faulty, remove it from the battery tray by loosening the hold-down bracket.
- Install the new battery, ensuring it is secure and connections are tight.

3. Starter Motor Inspection

Check Connections
- Inspect all starter connections; ensure they are clean and tight.
- If any corrosion is present, clean with a wire brush.
Test Starter Functionality
- If the battery is good but still clicks, use a multimeter to check for voltage at the starter terminal while someone turns the key.
- If voltage is present and the starter does not engage, the starter may need replacement.
Replace Starter (if needed)
- Remove the starter motor by disconnecting the negative battery terminal and removing the electrical connections.
- Unbolt the starter from the engine using the appropriate socket or wrench.
- Install the new starter in reverse order, ensuring all connections are secure.
