36V/48V 500A Series Motor Speed Controller 0-5KΩ Potentiometer Throttle Compatible with EZGO TXT, Club Car DS, Yamaha G-Series Replaces 1205M-5601

["BROAD SERIES FITMENT – Highly versatile speed controller compatible with older Series-wound motor golf carts utilizing a 0-5KΩ potentiometer throttle. Fits 1995–2013 EZ-GO TXT (Potentiometer type only), 1985–2013 Club Car DS (Series system), and Yamaha G-Series (G8–G19).","CRITICAL COMPATIBILITY NOTE – This unit operates on 36V or 48V systems with a 0-5KΩ throttle input. Strict Warning: It is NOT compatible with ITS (Inductive Throttle) systems, IQ systems, or Sepex (Separately Excited) motors. Please confirm your motor and throttle type before purchasing.","HEAVY-DUTY POWER UPGRADE – Capable of managing up to 500 Amps, this controller significantly boosts low-end torque and load-carrying capacity. Perfect for lifted carts, off-road applications, or vehicles carrying heavy cargo over varied terrain.","ROBUST PLUG BAR DESIGN – Engineered with 4 large, high-conductivity plug bars to handle massive current draw without overheating. The solid-state technology minimizes power loss and maximizes battery efficiency under heavy loads.","PREMIUM AFTERMARKET REPLACEMENT – Directly replaces Curtis 1205M-5601 and 1205M-5603. While suitable for DIY mechanics, we highly recommend upgrading your battery cables to 4-gauge (or thicker) and ensuring your solenoid matches the 500A rating to prevent electrical bottlenecks."]
