On the switch diagrams the O denotes the connected wires. For example n the ignition switch when off the black/yellow trace wires are connected, On and it's the red and orange and in the light position it is the red, orange and Gray wires . The red wire would be the one with the power. The others would show no voltage unless connected to the red. None of them go to ground. The red wire is "hot" the other wires go to the ignition to run the quad and to the lighting circuit. In the stop switch and the start switch push button when off the B/W and B/Y wires are connected, on run it's the O and O/W. The O would have power on it when the ignition is on and the red wire is connected to the Orange at the ignition switch. When you go to start the O/W wire also connects to the Y/G to give the spark and extra boos for starting. The only wire that is connected directly to the power is the red wire. The others all go to other circuits to connect power to them.
