Finally managed to get the 408 motor open, it was not easy. There is some minor rusting inside the motor but not too bad. I've attached a close up of the hall sensors. As it's second hand, I'm not the first to person to open this up and it looks like a previous owner has replaced a hall sensor...

That's a fantastic bit of info, thanks for finding that page! Cable looks in pretty good condition all the way into the hub, looks like I'm going to have to open the motor.

Have made better connections to the hall sensors now (pins and crocodile clips haha) and got more consistent results: Black=GND Yellow=13V steady, no matter what position the wheel is in Green=13V steady, no matter what position the wheel is in Purple=Switches nicely between 0V and 13V...

Thanks for getting back to me. Have turned battery on with multimeter probes in the throttle wires with throttle connected. Voltages are as follows: Purple=40.5V Red=4.8V Black varies from 0.8V at 0% to 4.0V at 100% throttle Yellow=GND From this I conclude that a) whoever designed this didn't...

Between ground and each phase is 73 kΩ, between controller-battery positive wire and each phase is 62 kΩ Since all resistances are virtually the same I assume that means my MOSFETS are probably ok? (And yes I've done electronic repairs before, I also do some hobby RC stuff so I have a...

I bought my first ebike kit 2nd hand last year and I've been using it every day to commute to work and love it to bits. The kit consists of a 36V 9Ah battery, Crystalyte 408 motor and Crystalyte 36V 20A "Journey" controller. Unfortunately it let me down this week, the motor started stuttering...
