- Check for corrosion at terminals.
- Clean terminals with a wire brush and a mixture of baking soda and water.
Test Battery:
- If voltage is low, recharge or replace the battery.
- Ensure the new battery is rated for the Ford Explorer specifications (typically 650 CCA).
Reconnect Battery:
- Reconnect the negative terminal securely.

3. Starter Motor Inspection and Replacement

Access Starter:
- Raise the vehicle and secure it on jack stands.
- Remove the undercarriage shield if necessary.
Test Starter:
- Check for proper voltage at the starter terminal during cranking.
- If voltage is present but the starter does not engage, replace the starter motor.
Remove Starter:
- Disconnect wiring harness and remove the mounting bolts using a socket set.
Install New Starter:
- Position the new starter and secure it with bolts.
- Reconnect the wiring harness.

4. Ignition Switch Inspection
