Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Tools Required: Wrench or socket set
Inspect the battery terminals for corrosion; clean them with a wire brush if necessary.
If the battery shows low voltage (<12.4 volts), replace it:
- Remove the battery hold-down bracket and disconnect the positive terminal followed by the negative terminal.
- Lift the old battery out and replace it with a new one, ensuring correct terminal connections (positive first, then negative).
- Reconnect the battery terminals and tighten securely.

3. Starter Motor Testing and Replacement

Tools Required: Socket set, multimeter
If the battery is functioning well and the issue persists, remove the starter motor:
- Disconnect the battery again before working on the starter.
- Locate the starter motor, and remove the necessary components for access (like the air intake if applicable).
- Unplug the electrical connector and remove the mounting bolts from the starter.
- Test the starter motor by bench testing it or replace it if it fails to engage.
- Install the new or tested starter motor by reversing the removal process. Torque bolts to manufacturer specifications.

4. Final Checks

Reconnect the battery terminals. Ensure all connections are tight.
Conduct a final visual inspection of all replaced components.
