Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, remote starter switch.
Ensure the vehicle is in a safe, well-ventilated area with the engine off.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Battery Inspection

Inspect Battery
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from terminals and cable ends using a wire brush.
- Reconnect terminals securely (positive first, then negative).
Check Battery Voltage
- Reconnect the battery and use a multimeter to measure voltage.
- If the voltage is below 12.4 volts, perform a load test or replace the battery.

3. Starter Motor Testing

Bypass the Ignition Circuit
- Locate the starter motor solenoid.
- Use a remote starter switch to connect the battery positive terminal to the starter terminal.
- If the starter engages and the engine cranks, the starter is functional.

4. Replace Components (if necessary)

If the battery and starter are both functional, check the ignition switch or wiring.
Replace any faulty components as needed, ensuring all connections are secure.
