1. Faulty Headlight Switch: The headlight switch could be faulty, causing a short circuit or power surge when it's turned on, which can interfere with the vehicle's electrical system and lead to stalling.
2. Electrical Overload: Turning on the headlights places an additional load on the vehicle's electrical system, which can cause the engine to stall if there is an existing issue with the charging system or battery.
3. Voltage Drop: When the headlights are turned on, it can cause a voltage drop in the electrical system, affecting the ignition system or fuel injection system and leading to stalling.
4. Wiring Issue: There could be a loose or damaged wire somewhere in the electrical circuit, causing a poor connection and power interruption when the headlights are switched on.
5. Alternator or Battery Problem: A weak or failing alternator may not be able to generate enough power to support the electrical demands of the headlights, resulting in a drop in voltage and stalling. Similarly, a faulty battery may not provide sufficient power to the electrical system.
To troubleshoot the issue accurately, it's recommended to have a qualified mechanic or auto electrician diagnose the problem. They can perform tests to identify the specific cause and provide the necessary repairs or replacements.
