Solution

1. Preparation

Gather tools: Multimeter, jumper cables, socket set, wrench set, fuse tester.
Ensure the vehicle is in park (or neutral for manual) and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Reconnect the battery and use a multimeter to measure the voltage.
- Voltage should be above 12.4 volts for a healthy battery.
If the voltage is low, charge the battery or jump-start the vehicle.
Clean the battery terminals with a wire brush to remove corrosion.
Tighten the battery connections to ensure a solid connection.

3. Starter Motor and Relay Testing

Locate the starter motor and inspect the wiring for damage.
Use jumper cables to bypass the starter motor:
- Connect the positive jumper cable to the starter terminal and the other end to the battery positive terminal.
- Connect the negative jumper cable to the starter housing and the other end to the battery negative terminal.
- If the starter spins, it may need replacement.
Test the starter relay:
- Remove the relay from the fuse box and use a multimeter to check for continuity when energized.
- Replace the relay if it fails the test.

4. Reassembly

Reconnect the negative battery terminal securely.
Ensure all connections are tight and corrosion-free.
Replace any blown fuses in the starting circuit.
