Wiring diagram
 

Can anyone tell me where all the wires go coming from the battery? and how come the charger has more that two output wires? It's a ultramotor 36V bike, and I would really like a wiring diagram of it's circuits. Bike works fine but I need a better understanding.

Is this your bike? http://site.nycewheels.com/manuals/U...-Manual-V1.pdf

A general comment is that the other charger wires could be for voltage or temperature sensors. I believe many batteries put the safety and control circuits inside the battery case, so they only need to supply the proper current-vs-voltage curve via two wires for charging.

THANKS dOC, THATS A START FOR ME.
