SUZUKI GN125/GS125 Rectifier (Voltage Regulator)

Fits 125cc-150cc Engines

5-Wire · OEM Specification · Plug & Play

📋 Overview

This rectifier (voltage regulator) is commonly used on SUZUKI GN125, GS125 and other 125cc-150cc engine models. It is a core component of the motorcycle charging system, converting AC from the alternator to DC, charging the battery, and regulating voltage output to protect the entire electrical system[citation:2][citation:3].

✨ OEM Quality: Manufactured to exact original specifications using quality electronic components, ensuring stable voltage output and reliable performance.

⚡ Operating Principle

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.

📌 Function in charging system: The rectifier converts AC from the alternator to DC, charging the battery and powering electrical components such as lights and horn[citation:3]. Without it, the battery would quickly drain and the vehicle would not run for extended periods[citation:2].
