I have just completed installing a 48v Magic Pie kit with internal controller.
Rechecked the power connections and the hall sensor plug and everything checks out.
I'm slightly puzzled by your comment, as the internal controller does not have a hall sensor plug, the wires are soldered directly onto the controller circuit board.
You should be able to check if the motor and controller are both working correctly by doing a simple test with the main harness disconnected.
A small piece of wire
(a reshaped non plastic coated paper clip works well for this) inserted between pins no 4 and 6 on the motor socket should make the motor run at full speed:
Make sure the wheel is raised off the ground and that the power is switched
ON before you insert the wire.
Be very careful to only put it into the correct holes or you could damage the controller or wiring.
If the motor spins correctly, this will indicate that the battery, speed controller and the throttle wiring in the motor harness are all working correctly. Therefore the fault must be somewhere in the main harness, throttle or brake switches
(or one of the connectors).If the motor does not spin when 4 and 6 are linked, and the wheel is "lumpy" and difficult to turn with the power off, it sounds like the controller may have failed.
Do you get any beeps from the controller?
