On the wire diagram, if it has a ground out icon, next to the item, then it has to be grounded to the frame. since my diagram is for a 81, I dont know what an 76 one looks like. Oh that drewcifers bike. the 81 only has it marked near the battery. but it doesn't say the handle bar is the ground point for the starter. so I don't know. I felt to play it safe, and ran a pig tail. You do have the colorized version of the wire diagram don't you? from the top of the garage, under wire diagrams, (maybe tech tab)
