Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a safe, well-ventilated area.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Sub-steps:
1. Clean battery terminals using a wire brush to remove corrosion.
2. Reconnect the battery and check the voltage again.
3. If the battery is below 12.4 volts, replace it with a new one of the same group size.
4. Secure the new battery terminals tightly.

3. Starter Motor Replacement

Sub-steps:
1. Disconnect the negative battery terminal again.
2. Locate the starter motor (typically on the driver’s side near the transmission).
3. Remove the electrical connections from the starter (mark them for proper reinstallation).
4. Remove the mounting bolts using a socket set and carefully take out the starter.
5. Install the new starter by reversing the removal steps, ensuring all connections are secure.

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Attempt to start the engine to check if the problem is resolved.
3. If still non-functional, recheck all connections and components involved.
