my Ford Mustang S650 (2024-Present) dashboard lights are flickering, what can I do?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.

Tools Required:

• Multimeter
• Socket set
• OBD-II scanner
• Wire brush (for cleaning battery terminals)

2. Inspect and Clean Battery Connections

1. Disconnect the negative (-) battery cable first, followed by the positive (+) cable.
2. Clean the battery terminals and cable ends with a wire brush to remove any corrosion.
3. Reconnect the positive (+) battery cable first, followed by the negative (-) cable.

3. Test Battery and Alternator

1. With the multimeter, check the battery voltage again. Ensure it reads around 12.6 volts.
2. Start the engine and measure the voltage at the battery terminals; it should be between 13.7 to 14.7 volts.
3. If the voltage is outside this range, the alternator may need replacement.

4. Inspect Alternator Belt

1. Open the hood and locate the alternator.
2. Check the alternator belt for any signs of wear or looseness; it should have minimal play.
3. If the belt is worn or loose, replace it according to the manufacturer's specifications.

5. Replace Faulty Components

1. If the battery or alternator fails the tests, replace the faulty component.
   • For battery replacement, ensure to select a battery that meets the specifications for the Mustang S650.
   • For alternator replacement, ensure proper alignment and torque specifications during installation.
