- Tighten loose connections.
Replace Battery (if needed):
- Remove the battery by disconnecting the negative terminal first, followed by the positive terminal.
- Lift the battery out of the tray and place a new, fully charged battery in its place.
- Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Testing and Replacement

Test Starter:
- Remove the starter motor from the engine by disconnecting the electrical connectors and bolts.
- Use a multimeter to check for continuity and functionality.
Replace Starter (if faulty):
- Install the new starter motor, ensuring all connections are secure.
