my Ford Mustang S650 (2024-Present) won’t start but makes a clicking noise, what could be wrong?

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the ignition is off.
• Gather tools: multimeter, socket set, wrench set, and safety gloves.
• Disconnect the battery to ensure safety during repairs.

2. Battery Inspection and Replacement

1. Inspect battery terminals:
   • Remove corrosion using a battery terminal cleaner or a mixture of baking soda and water.
   • Tighten any loose connections.
2. Test battery:
   • Use a multimeter to check voltage; if below 12.4 volts, charge or replace the battery.
3. Replace battery if necessary:
   • Remove the negative (-) terminal first, then the positive (+) terminal.
   • Remove the battery hold-down clamp and lift the battery out.
   • Install the new battery, connecting the positive (+) terminal first, followed by the negative (-) terminal.
   • Tighten the hold-down clamp securely.

3. Starter Motor Inspection

1. Access the starter motor:
   • Raise the vehicle using jack stands if necessary.
   • Locate the starter motor, typically found near the transmission.
2. Test starter functionality:
   • Disconnect electrical connections to the starter motor.
   • Use a multimeter to check for continuity and proper voltage at the starter terminal.
3. Replace starter motor if defective:
   • Remove the starter motor bolts using a socket set.
   • Disconnect and remove the starter from the vehicle.
   • Install the new starter by reversing the removal steps and ensuring secure connections.

4. Ground Connection Verification

1. Inspect ground connections:
   • Locate ground cables from the battery to the chassis and engine.
   • Ensure connections are tight and free from corrosion.
2. Clean and tighten connections if necessary:
   • Use a wire brush to clean any corroded areas on the ground points.
   • Securely tighten all connections.
