Golf Car Catalog offers many voltage regulators for use with EZGO, Club Car, Yamaha, Columbia, and Harley-Davidson golf carts, utility vehicles, and personnel carriers. Some popular voltage regulator brands include Hitachi and Bosch.
The voltage regulator is responsible for limiting or regulating the amount of power sent back to the battery for recharge. When your golf cart is started, the starter generator acts as a starter motor to start the engine to spin. But, once the internal combustion of the engine is established, the starter becomes a generator. It is then propelled by the combustion and uses this power to send power back to the battery. This power flow is often irregular due to the rpm variations of the engine. These power fluctuations are very bad for your battery. Instead, a constant steady flow of voltage is preferred. The voltage regulator helps to ensure that this recharge voltage never exceeds about 14.5 volts (depending on the manufacturer). This recharges the battery while pro viding smooth constant voltage for longer battery life.
