Large electric scooters

I have an issue regarding the electrical wiring on my 60v 2011 dream Ryder by Volt Canada I know that X-Treme bikes makes one almost identical which is the XB-700Li. I would like to know if anyone has a wiring diagram of either of these bikes. The problem I have is the emergency power cut off switch seems like its not connected or a faulty switch, either way it doesn't shut off the power. Also I wanted to know whether the headlight voltage is 12/ 24/ 36/ 48/ 56/ volts. Volt Canada can't give me a definite voltage, and the bulbs that are in the bike now don't have anything on them.
