The alternator pigtail connector performs several essential functions in the vehicle electrical system:
Power connection: It connects the alternator to the vehicle's battery and electrical system, allowing the alternator to deliver power and charge the battery.
Voltage regulation interface: It connects to the voltage regulator, allowing it to monitor and control the alternator's output voltage, ensuring the battery is properly charged and preventing overcharging.
Sense wires: Some pigtail connectors have sense wires that monitor battery voltage and help regulate the alternator's output for a consistent charge.
These connections ensure the alternator operates properly, maintaining the health and reliability of the vehicle's electrical system.
