Tools Required:

Multimeter
Socket set
Jumper cables
Wrench set

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion using a wire brush.
- Tighten loose connections.
Test and Replace Battery (if necessary)
- If the battery voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.
- Install the new battery, ensuring correct polarity (positive to positive, negative to negative).

3. Starter Motor Inspection

Access Starter Motor
- Remove any undercarriage covers if applicable.
- Locate the starter motor, usually found near the transmission.
Check Connections
- Inspect wiring and connections to the starter motor for any signs of wear or damage.
- Tighten any loose bolts or connectors.
Test Starter Motor
- With the negative battery terminal still disconnected, use jumper cables to apply power directly to the starter motor to see if it engages.
- If the motor does not engage, it may need to be replaced.

4. Reassembly and Final Checks

Reconnect Battery
- Reattach the negative terminal after all repairs are completed.
Test Start the Vehicle
- Turn the ignition key to see if the vehicle starts properly.
