1. Faulty Alternator: The alternator is responsible for charging the battery and supplying power to the electrical components in your vehicle. If the alternator is malfunctioning, it may not be able to generate sufficient power, causing the dash lights to flicker and the engine to stall.
2. Battery Issues: A weak or damaged battery can also cause dash light flickering and stalling. If the battery is not holding a charge properly or has faulty terminals, it may not be able to provide enough power to the electrical system, resulting in these symptoms.
3. Loose or Corroded Wiring: Loose or corroded wiring connections in the electrical system can disrupt the flow of power, leading to flickering dash lights and stalling. Check the wiring harness and connections near the alternator, battery, and ignition switch for any loose or damaged wires.
4. Ignition Switch Problems: A faulty ignition switch can cause intermittent power supply to the electrical system, resulting in dash light flickering and stalling. If the ignition switch is worn out or damaged, it may not properly engage the starter or maintain the electrical connection, causing these issues.
5. Fuel System Issues: In some cases, fuel-related problems, such as a clogged fuel filter or a faulty fuel pump, can cause the engine to stall and the dash lights to flicker. Ensure that the fuel system is functioning correctly by checking the fuel pressure and inspecting the fuel lines and filter.
6. Computer Sensor Issues: Faulty sensors in the engine management system, such as the oxygen sensor, mass airflow sensor, or crankshaft position sensor, can provide incorrect information to the engine controller, leading to stalling and flickering dash lights.
If you encounter these symptoms, it's recommended to have your vehicle inspected by a qualified mechanic. They can diagnose the root cause of the issue and perform the necessary repairs to ensure the proper functioning of your car's electrical and engine systems.
