Tools Required: Multimeter, socket set, wire brush (for cleaning terminals).
Sub-steps:
1. Inspect and clean the battery terminals using a wire brush to remove any corrosion.
2. Reconnect the battery terminals securely.
3. If the battery voltage is low, charge the battery or replace it if it fails the load test.

3. Starter Motor and Solenoid Check

Tools Required: Socket set, wrench set, torque wrench.
Sub-steps:
1. Locate the starter motor, which is typically mounted on the engine block.
2. Disconnect the electrical connections to the starter motor.
3. Remove the starter motor mounting bolts using a socket set.
4. Inspect the solenoid for any visible damage or corrosion.
