It was idling when it made a backfire noise and died. I no longer get any spark when I try to start it. The kill switch on the handlebars works fine. The tether switch has three wires coming from it and only 2 are connected when the cap is on the switch. The wires are black, green, and white. The black and green are the 2 that connect when I put the cap on. The white wire does not connect to either of the other wire with the cap on or off. I do not have a wiring diagram for troubleshooting.
