My first thought would be the bearing encoder mounted in the motor.
Second thought would be corrosion in the wiring harness between the controller and bearing encoder. Sent from my iPhone using Tapatalk |

there was a tap into the white wire that runs to the encoder on the motor. the wire was suppost to be tapped into the brake switch wire which on this golf cart is gray . ( used a meter to identify the wire)
could that have fried the encoder ???? |

Re: 2008 electric rxv Ezgo slow forard than stall, slow reverse than stall plz help
OK reread the original post. Missed that this was a Danaher to Curtis conversion. My goof.
Yes if the wire was connected to the wrong white or grey wire, the controller could have been damaged, but the fact that it moves makes me think the controller survived and the issue was with the bearing encoder. The encoder is really just a sensor the allows the controller to count pulses. So, yes, the miss tapped wire could be confusing the controller. I think it would be hard to damage the encoder. Correct the wiring (if needed) and see what happens.... 18 months ago I started a thread where chronicled my trials and tribulations with a Danaher to Curtis Conversion. On these seasoned (more vintage ) carts, the Curtis controller will complain about a lot of stuff the Danaher ignored like throttle and brake switches having some resistance when closed, and some corrosion in the wiring harness. The bearing encoder has some very fine wires which can easily break when they age. (At least that was my issue when I re-wired my cart.) So depending on how much pressure / jostling the encoder wires took, the actual splicing of the line could have moved a wire enough to break it. Please understand that I’m guessing based on what I’m reading in the posts. Again, the fact that the cart moves a short distance than stops, and putting the cart in tow mode releases the motor brake makes me think the issue is with the encoder, or the wiring between the encoder and the controller. Let us know if you have other questions or want more info. (Other than the EZGO technicians that monitor some threads, we’re all cart enthusiasts - or live on a golf course! We’ve mostly learned via education by error...) Sent from my iPad using Tapatalk |

for the rxv encoder (throttle/brake/motor) is that considered the bearing encoder ? |
