Solution

1. Preparation

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

2. Battery Inspection and Replacement

Sub-steps:
1. Clean the battery terminals using a wire brush to remove corrosion.
2. Reconnect the battery terminals and test the voltage again.
3. If the voltage is still low, replace the battery with a new one (ensure it matches OEM specifications).
Tools Required: Wire brush, socket set, multimeter.

3. Starter Motor Replacement

Sub-steps:
1. Remove any components obstructing access to the starter motor (e.g., air intake or engine covers).
2. Disconnect the wiring harness from the starter motor.
3. Remove the starter motor mounting bolts using a socket set.
4. Install the new starter motor by reversing the removal steps. Torque the bolts to manufacturer's specifications (usually around 15-25 Nm).
Tools Required: Socket set, torque wrench.

4. Reconnect Battery

Reconnect the battery positive terminal followed by the negative terminal.
Ensure all connections are secure.
