The Electrical System of a 91 EZGO Marathon Golf Cart
Before we dive into the specifics of the wiring diagram, let’s take a quick look at the electrical system of a 91 EZGO Marathon golf cart.
The electrical system of a golf cart consists of a battery pack, a charger, a controller, and electric motors. The battery pack provides the power to the electric motors, which drive the wheels of the golf cart. The controller regulates the power flow between the battery pack and the motors, while the charger is used to recharge the battery pack.
In addition to these components, there are also various switches, relays, fuses, and other electrical devices that are used to control and protect the electrical system of the golf cart.
The Battery Pack
The battery pack is the heart of the golf cart’s electrical system. It provides the power that drives the electric motors and is responsible for the overall performance of the golf cart. The 91 EZGO Marathon golf cart uses six 6-volt batteries wired in series to provide a total of 36 volts to the electric motor.
The Charger
The charger is responsible for recharging the battery pack. It is designed to provide a constant current to the battery pack until it is fully charged. Once the battery pack is fully charged, the charger will automatically shut off to prevent overcharging.
The Controller
The controller is responsible for regulating the power flow between the battery pack and the electric motors. It is designed to monitor the speed and torque of the electric motors and adjust the power output accordingly. This helps to maximize the performance and efficiency of the golf cart.
Electric Motors
The 91 EZGO Marathon golf cart uses a series-wound electric motor to drive the wheels. These motors are designed to provide high torque at low speeds, making them ideal for use in golf carts.
