ok so you're almost definitely better off replacing the switch, a new switch is liek 5 bucks. but the way that works if youre set on repairing it, the ball is helf in the selector by the swpring and pops out against the terminals which just clamp the wires.
i definitely didn't have all the wires you're talking about but if it's the light switch, ant ya just start the bike and connect wires until you have the desired effect?
on my arrow it was just one power wire and the switch selected whether it conencted to the high beam or low beam output that went straight to the headlight. unless we're lookin at some other switch
