Golf Cart CLUTCH All golf cart (much like cars) have a clutch, which is a part of the drivetrain that helps the put the power of the motor through to the wheels/ ground. Golf cart clutches are also known as Continuously Variable Transmission (or CVT). This transmission is comprised of two different clutch- es connected together by a golf cart drive belt. The two clutches are the: • Golf Cart Drive Clutch (Primary) • Golf Cart Driven Clutch (Secondary) The drive (primary) clutch connects to the engine crankshaft while the driven (secondary) clutch is bolted onto the cart’s input shaft. The Drive Clutch & Driven Clutch work in tandem to smoothly propel your golf cart forward when power is applied via the accelerator pedal. Con- versely, these same clutches help with smooth deceleration when the cart is in motion and the accelerator is released (even if the brake is not yet depressed). Three things can indicate that your golf cart clutch is going bad: • Your cart’s initial acceleration is jerky • It feels as if power is slipping while your cart is climbing incline terrain/hills • Your cart has varying top-end speed (alternating between fast and slow) Golf Cart CONTROLLER Golf Cart Controllers are an extremely popular part to either replace (due to age or malfunction) or upgrade for your golf carts power. The golf cart controller / golf cart speed controller does exactly what its name implies: controls the speed and power of your golf cart. If you are looking to either replace or upgrade your golf cart controller, the most important thing you can do is think about how your cart gets used most, which will tell you how much power you need out of your controller (and motor): • 200-300 Amp Controller: Perfect for your cart 26 WWW.GOLFCAROPTIONS.COM if it will be used for normal rounds or golf or trips around the neighborhood with up to two passengers • A controller this size is normally paired with a small 2hp to 5hp motor • This is the typical controller size on 36-Volt golf carts • 300-600 Amp Controller (upgraded): Great for carts with a rear seat or cargo bed, or carts that will need to climb steep hills. When carrying 4 or more passengers/heavy loads, or climbing steep grade, an upgraded controller (and motor) are recommended. • A Controller this size is normally paired with a larger 5hp to 10 hp motor • Typical controller size of 36-48 Volt golf carts Golf Cart SOLENOID Solenoids act as a relay/switch between your golf cart batteries and your golf cart starter/generator or traction motor. Think of a solenoid as the gate- keeper of battery current. It allows (or disallows) current to flow through to your cart’s starter/ generator to start your engine (on gas carts). On electric carts, it functions the same way, except the solenoid allows or disallows current to the traction motor (instead of the starter). Solenoids in golf carts are designed to work the entire time you press the pedal down when accel- erating/driving. This means solenoids work hard all the time; so they tend to go bad. It’s just a fact of life! Luckily, they aren’t too expensive and we carry golf cart solenoid replacements for all golf carts.
