Install the New Battery:
- Place the new battery into the tray, ensuring the terminals are positioned correctly (positive to positive and negative to negative).
- Reinstall the hold-down brackets.
- Connect the positive terminal first, then the negative terminal.

3. Starter Motor Inspection/Replacement

Access the Starter Motor:
- Depending on the engine configuration, remove any necessary components (e.g., air intake duct) to gain access.
Remove the Starter Motor:
- Disconnect the electrical connectors from the starter motor.
- Remove the mounting bolts (typically 2-3 bolts).
- Carefully pull the starter motor out of its housing.
Install the New Starter Motor:
- Position the new starter motor in place and secure it with the mounting bolts (torque to manufacturer's specifications).
