Solution

1. Preparation

Gather tools: multimeter, socket set, jumper wire, fuse tester, and safety gloves.
Ensure the vehicle is parked on a flat surface, and the ignition is turned off.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the battery voltage.
- If the voltage is below 12.4 volts, proceed to charge or replace the battery.
Clean Battery Terminals
- Disconnect the negative terminal first, followed by the positive terminal.
- Clean any corrosion with a wire brush and a mixture of baking soda and water.
- Reconnect terminals securely.
Replace Battery (if necessary)
- Remove the old battery using a socket set.
- Install the new battery, attaching the positive terminal first, then the negative terminal.

3. Starter Motor Inspection and Testing

Access the Starter Motor
- Raise the vehicle using a jack and secure it with jack stands.
- Locate the starter motor under the vehicle.
Test Starter Motor
- Disconnect wiring from the starter motor.
- Use a jumper wire to connect the positive terminal of the battery directly to the starter's positive terminal.
- Listen for a click or attempt to crank; if it doesn't respond, the starter may need replacement.
Check Wiring and Connections
- Inspect the wiring harness to the starter for any signs of wear or damage.
- Ensure all connections are tight and free of corrosion.
