As a safety note, the better the regulator, the brighter your lights. And brighter lights equal greater visibility.The purpose of a rectifier is to prevent the capacitor from discharging prior to ignition (turning the key). Upon ignition, the rectifier stops charging the capacitor, allowing the capacitor to transfer the 400-600 Volt charge to the ignition coil.Please note that this volt
