Solution

1. Preparation

Gather tools: Multimeter, socket set, screwdriver, wire brush, safety gloves, and safety goggles.
Disconnect the negative battery cable to prevent accidental electrical shorts.

2. Battery Inspection

Inspect Terminals:
- Remove the battery terminals using a socket set.
- Clean any corrosion from the terminals and battery posts with a wire brush.
- Reconnect the terminals securely.
Test Battery:
- Connect the multimeter to the battery terminals.
- If the voltage is below 12.4 volts, charge or replace the battery.

3. Starter Motor Inspection

Access the Starter:
- Lift the vehicle using a jack and secure it on jack stands.
- Locate the starter motor (usually on the lower side of the engine).
Test Starter Function:
- Disconnect the wiring harness from the starter.
- Use a jump wire to connect the battery positive terminal to the starter terminal (ensure vehicle is in neutral or park).
- If the starter engages and spins, it may need replacement; if it does not, further diagnosis of wiring may be needed.

4. Wiring and Connections

Inspect Wiring:
- Check all connections and wires leading to the starter and battery for signs of wear or damage.
- Repair or replace any damaged wiring as needed.

5. Reassemble and Test

Reconnect all components, ensuring all connections are secure.
Reconnect the negative battery cable.
Attempt to start the vehicle.
