| On-Board Computer (OBC) | Shows the wiring from the OBC to the charger receptacle, charger fuse, and DC converter. |
| Solenoid | Shows the wiring from the solenoid to the motor, controller, and other components. |
Battery Pack
The battery pack section of the wiring diagram shows the wiring from the batteries to the charger receptacle, charger fuse, and solenoid. The batteries are connected in series to create a 48-volt system. The charger receptacle allows you to plug in a charger to recharge the batteries. The charger fuse protects the batteries and the OBC from overcharging. The solenoid is an important component that controls the flow of electricity from the batteries to the motor.
If you’re experiencing issues with your cart not charging or not having enough power, then the battery pack section is a good place to start troubleshooting.
Charger Circuit
The charger circuit section of the wiring diagram shows the wiring from the charger receptacle to the charger fuse, OBC, and DC converter. The OBC is responsible for controlling the charging process and ensuring that the batteries are charged safely and efficiently. The DC converter is responsible for converting the 48-volt DC power from the batteries to 12-volt DC power for accessories such as lights, horns, and radios.
If you’re experiencing issues with your cart not charging or accessories not working, then the charger circuit section is a good place to start troubleshooting.
Controller
The controller section of the wiring diagram shows the wiring from the controller to the motor, solenoid, and other components. The controller is responsible for controlling the speed and direction of the motor. It receives input from the accelerator pedal and sends signals to the motor and solenoid to control the movement of the cart.
If you’re experiencing issues with your cart not moving or not moving properly, then the controller section is a good place to start troubleshooting.
DC Converter
The DC converter section of the wiring diagram shows the wiring from the DC converter to the battery pack and other components. As mentioned earlier, the DC converter is responsible for converting the 48-volt DC power from the batteries to 12-volt DC power for accessories. This section also shows the wiring from the DC converter to the lights, horn, and other accessories.
If you’re experiencing issues with your cart’s accessories not working, then the DC converter section is a good place to start troubleshooting.
On-Board Computer (OBC)
The OBC section of the wiring diagram shows the wiring from the OBC to the charger receptacle, charger fuse, and DC converter. As mentioned earlier, the OBC is responsible for controlling the charging process and ensuring that the batteries are charged safely and efficiently. This section also shows the wiring from the OBC to the battery light, which indicates the status of the charging process.
If you’re experiencing issues with your cart not charging or the battery light not working, then the OBC section is a good place to start troubleshooting.
Solenoid
The solenoid section of the wiring diagram shows the wiring from the solenoid to the motor, controller, and other components. The solenoid is an important component that controls the flow of electricity from the batteries to the motor. It’s controlled by signals from the controller, which tells it when to open and close.
If you’re experiencing issues with your cart not moving or not moving properly, then the solenoid section is a good place to start troubleshooting.
