Solution

1. Preparation

Tools Required: Wrench set, multimeter, jumper wires
Disconnect the negative battery terminal to ensure safety before starting work.

2. Battery Inspection and Replacement

Use a multimeter to check the battery voltage.
- If the voltage is below 12.4 volts, charge or replace the battery.
Clean the battery terminals with a wire brush to remove any corrosion.
Ensure the battery terminals are securely connected.

3. Starter Motor Test and Replacement

Locate the starter motor (typically mounted on the engine block).
Use jumper wires to bypass the starter solenoid:
- Connect one end of the jumper wire to the battery positive terminal and the other end to the starter terminal.
If the starter motor engages and the engine cranks, replace the starter motor.
- To replace, remove the mounting bolts and disconnect the electrical connectors from the starter.
- Install the new starter motor by reversing the removal steps.

4. Ignition Switch Inspection

Remove the steering column cover to access the ignition switch.
Use a multimeter to test for continuity across the ignition switch terminals when the key is turned to the "start" position.
If there is no continuity, replace the ignition switch.
