Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and a wrench.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Maintenance

Remove Battery Cables:
- Use a wrench to disconnect the negative (-) terminal first, followed by the positive (+) terminal.
Clean Battery Terminals:
- Use a wire brush to clean any corrosion from the battery terminals and cable ends.
Reconnect Battery:
- Reconnect the positive (+) terminal first, followed by the negative (-) terminal.

3. Starter Inspection

Locate the Starter:
- Refer to the vehicle's service manual to find the starter's location.
Remove Starter:
- Disconnect the wiring harness from the starter.
- Unbolt the starter using a socket set and remove it from the vehicle.
Test Starter:
- Bench test the starter by connecting it to a charged battery; if it doesn't spin, replace the starter.

4. Check Connections

Inspect Wiring:
- Check all wiring leading to and from the starter for fraying or damage.
Tighten Connections:
- Ensure all connections are tight and secure on the battery, starter, and ignition switch.

5. Reassembly

Reinstall Starter:
- Position the starter back in place and secure it with bolts to the specified torque (typically around 12-15 ft-lbs).
Reconnect Wiring:
- Reconnect the wiring harness to the starter.
