Our 4-pin rectifier (or voltage regulator) for Coleman AT125-EX and AT125-UT ATVs is an affordable replacement part that is a perfect substitute for a lost, broken, or faulty regulator. The Coleman AT125-EX/AT125-UT rectifier prevents the capacitor from discharging prior to ignition. Upon ignition, the rectifier stops charging the capacitor, allowing the capacitor to transfer the charge to the ignition coil. As a safety note, the better the regulator, the brighter your light. And brighter lights equal greater visibility.
