Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, flat area.
Disconnect the negative battery terminal to avoid electrical shock.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and battery posts using a wire brush.
Replace Battery (if necessary):
- If the battery voltage is low (below 12.6V), replace with a new battery of the same specification.
- Reconnect the positive terminal first, then the negative terminal.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- If the battery is good, locate the starter motor.
- Use jumper cables to connect the starter directly to the battery to check if it engages.
Replace Starter Motor (if necessary):
- Remove any components blocking access to the starter motor.
- Disconnect electrical connections from the starter.
- Unbolt the starter motor from its mounting bracket and remove it.
- Install the new starter motor and reconnect all electrical connections.
