1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Prepare a clean workspace to avoid contamination.

2. Battery Inspection and Replacement

Inspect Battery:
- Check for physical damage or leaking.
- Clean any corrosion from terminals with a wire brush and a mixture of baking soda and water.
Replace Battery (if necessary):
- Remove the positive terminal first, followed by the negative terminal.
- Remove any mounting brackets.
- Install the new battery, connecting the positive terminal first, followed by the negative terminal.
- Ensure terminals are tight and secure.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- Reconnect the battery.
- Use a multimeter to check voltage at the starter solenoid while attempting to start the engine.
- If voltage is present but the motor does not engage, proceed to replace the starter.
