How To: Replace V11 Control Board

How To: Replace the V11 Driver Board

• Access the controller: 
  • Using the video guide as a reference, remove the slide covers with saddle pads, top metal cage, and controller cover: Follow the first part of this video to expose the controller.
• Unplug the controller from power: 
  • Disconnect the two large XT90 connectors.
  • Push the power button on the unit to discharge the controller.

• Remove the motherboard: 
  • This board sits on top of the main driver-board. Disconnect the wires connected to this upper board.
  • It’s secured on by 4 screws; each screw goes into a metal post beneath. Remove these screws and the motherboard.
• Remove the Driver-board: 
  • Note the positions of the connectors to the board with pieces of tape, then disconnect the connectors.
  • The board is secured to the Wheel with a screw for each MOSFET and each of the 4 posts. The posts are also screwed into the heatsink. Remove all of these screws and posts—make sure to not miss the 2 MOSFET screws located at the rear of the board.
  • Carefully lift the board away from the unit.

• Prepare the new board:
  • If the new controller was shipped with the heatsink, remove that component.
  • Ensure the large insulating pad is positioned under the controller, by the MOSFET posts.
  • There is a short strip for the 2 MOSFETs at the end & a long strip for the bank of MOSFETs.

• Install the new driver board:
  • Start with screwing down the 4 brass posts to correctly position the new controller. 
  • Screw down all MOSFET screws with the small spacers on them.
  • Connect all wires in their designated ports—leave the large yellow battery wires for last.
  • Reinstall the motherboard on the 4 brass posts.
  • Connect all wires to the motherboard in their correct positions. 
  • Connect the two large power connectors.
• Test the Wheel: 
  • Turn the unit on and connect to it with the app.
  • Update the firmware to sync the driver and motherboards.
  • Roll the unit forwards/backward, test all other functions.
  • Once the Wheel is fully tested, power it off and reassemble the unit following the same video used at the beginning of the guide.
