Re: Help wiring g8 controller
Here's the wiring diagram:
Looks like your B+ runs from the solenoid & splits to the controller and the "S" terminal of the Fwd / Rvs switch. B- runs from the controller to the pack - battery terminal and on to the charger socket -. M+ to motor A2 terminal. |

Re: Help wiring g8 controller
FYI your controller should look like this. If it is exposed (no box) I don't think it could last even if you figured out where / how to wire it.

Re: Help wiring g8 controller
My cart actually works how it is wired but NOT RIGHT! It is full throttle all the time as soon as selenoid clicks or as soon as pedal switch activates and energizes selenoid the wheels spin out and its full throttle. U can feather the pedal and slow down but I know its not right. I bought the cart with broken brush in motor. I'm thinking from the torque from full throttle take offs. I unplug speed sensor and same thing it doesn't need to be connected. So thought maybe someone wired to make it more torque and bypassed the controller somehow.

Re: Help wiring g8 controller
Are controllers all the same 36 volt interchangeable or I would have to change other parts? this cart is very hard to get parts for and double then all other models I think new controller was over $1000

Re: Help wiring g8 controller
Before you start shopping for a controller, have you checked the throttle sensor? Should be a 3 wire bundle. Item 10 in that wiring diagram.
