2. Battery Inspection and Replacement

Check Battery Condition:
- Remove the battery from the vehicle if it is faulty.
- Clean the terminals with a wire brush and baking soda solution if corroded.
Replace Battery:
- If the voltage is low or it fails a load test, replace with a new battery of the same specifications (usually 12V, check owner's manual).
- Install the new battery, connecting the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection and Replacement

Remove Starter Motor:
- Disconnect the wiring harness from the starter motor.
- Remove the bolts securing the starter motor to the engine block using a socket set.
Test Starter Motor:
- Use a multimeter to check for continuity and proper operation.
