Z808 Replace Control Unit
These brief instructions should help you to replace the control unit on your bike. To do this, please proceed as follows:
First unlock the battery lock with the key provided and remove the battery from the battery holder.
Dismantle the upper battery mount. To do this, you must completely unscrew five screws with a standard screwdriver.
You can then remove the upper battery mount from the frame.
Let them hang down the frame temporarily.
Dismantle the lower battery holder. To do this, you have to completely unscrew three screws with a standard screwdriver.
Use a narrow slotted screwdriver to remove the lower battery holder from the frame.
Pull the power supply cables (red and black cables) down slightly out of the frame opening and unplug this connection. In order to pull out the cables downwards, it is helpful if you push these cables from above.
Disconnect the motor cable plug connections and pull it completely down and out of the frame so that you have more space for the next step. Pull the plug connection between the control unit and the wiring harness down out of the frame far enough so that you can unplug it (you will find information on the pin assignment at the end of these instructions).
Pull the control unit up out of the frame and connect the cables 1 to 1 from
the old to the new control unit.
Now place the new control unit in the frame and assemble all other components
in reverse order.
