on opening up the controller housing for the 'junk' bike i am trying to fix i found burnt and fused connectors on 2 of the 3 phase feeds to the motor (blue/yellow) the third green was covered in gaffer tape..
snipping the burnt on sleeve on the blue and yellow wires to reveal the wire/connector i tested the resistance between blue/yellow, green/yellow, and blue/green.
all zero'd out 200k range iirc
Not knowing much at all i cut the controller connections and retested the motor wires disconnected from the controller with the Same results.
the feed cable into the motor does Not look twisted at all, BUT its external support spring is rusted to buggery and back.
My Next steps are to remove the wheel and hub, open it, and check the continuity of the feed wires and confirm the coils are burnt out and shorted or not?
The wheel is not spoked but a cast alloy job so replacing wont be easy.. Hmmm
any advise or direction welcome, its a 250w or perhaps 350w motor? No visible etchings or markings on the motor casing i have seen.
