The Club Car Precedent Voltage Regulator is a very aptly named product. It is responsible for safely recharging your battery while your engine is running. The starter generator is doing most of the heavy lifting. It generates 18-20 volts of power as the cart is putting around. This is way too much voltage to try and recharge a 12-volt battery. That is where the regulator comes in. It takes the 18-20 volts produced by the generator and drops it down to 13.5 to 15.5 volts, so your battery does not become a bomb below your bottom. The last thing you need is your neighbors wondering what you are building in your garage when they hear your battery explode.This golf cart voltage regulator has a quick connect three-pin connector. It will fit the 2004-2015 Club Car Precedent models. Do not try and use it on the DS models as it will have no place to plugin. Call Buggies Unlimited today and get one ordered.
