Bought this bike used for a pretty great deal. Love the way it rides and the rack system. Unfortunately all the controller parts and wiring harnesses were removed. I figured I could buy a new controller and get it going for pretty cheap, unfortunately so far that has not been the case. Izip has *most* of the parts, at $500 but no wiring harness, which is just too much to repair this thing. Originally the controller was located in the center tube and not the motor.
This is the controller I purchased, the 750w version as it has the same "3 pin" plug that is actually a 9 pin

C965 is the display

The battery is healthy and is showing 52.5v on a 48v battery. Charging system works fine but I cannot get the controller to power up at all, completely unresponsive.
I spoke with Izip, apparently this is a "smart" battery and there is a "data" wire coming off the battery and that's why I cannot get the new controller to power on, which doesn't make sense to me, so I'm here to learn. Apparently it is called a "wettsen" system and I cannot find any information about it.
That, or the controller/display I received is bad, which is possible I guess, when I upgraded the controller on my wife's bike I received 6 bad units from Amazon before ordering from Aliexpress
The battery is a 3 pin connector, standard red and black but with a yellow wire coming off the center pin of the battery connector. The battery is located in the center of the bike in the seat tube. Am I wrong to assume I should at least be able to get the system to power on or respond?
