Not familiar with that particular cart. Do you know its history?
Any chance this cart was flooded? to BGW! |

ITS is an ezgo part. G8 motor controller wires are directly connected inside the controller, so mis-wiring is unlikely, all this points to a failed controller.

And that's exactly where I was going. Was just curious about flooding because of the motor and this. I have had a wet controller do this.

I too had a Wide Open Throttle (WOT) event on my cart when a very small amount of water leaked into the controller when “lightly” washing the controller area of my cart. Many older controllers are NOT waterproof and even the smallest amount of water can play havoc with the electronics in a controller.
Disconnect and check that you are getting the correct throttle response for your cart. If the throttle response is correct, then it could be a controller issue ... possibly caused by water entering the controller. I was able to salvage my controller by taking the end cap off of it and evaporating the moisture out of it. I think that was about 3 years ago and it is still working fine. Other BGW members have not been as fortunate. If you don’t know the history of this cart, after checking the throttle response successfully, I would suggest disconnecting the controller and give it a shake test to see if any water is sloshing around in it. Maybe even drill a few drain holes 🕳 to check for water. |
