Quote from: aviationfred on July 25, 2016, 11:35:22 PMI will try too explain the circuit. Starting at the clutch switch.The Black/Yellow wire goes to the Diode and the Main Relay. The Blue/Yellow wire goes to the same Diode, the Sidestand Relay AND the Sidestand Switch.The Diode does not have a chassis ground going to it. I am going to say the Diode is not the issue.The Blue/Yellow wire that you ground allows everything to work properly, indicates to me that the problem lies with a ground problem.The Sidestand Relay has a ground wire going to it. Also the Sidestand switch has a ground wire going to it. I am going to say.....the problem lies with one of 3 components 1: Clutch switch, 2: Sidestand Relay, 3: Sidestand Switch. Or.....you have a ground wire from either the Sidestand Switch or the Sidestand Relay that has been cut or not connected properly.I hope this helps. If this is clear as mud, I apologize. I am an electrician by trade and I can see the circuit clear as a bell.According to Partzilla, all of the parts, (Clutch switch, Sidestand switch, Sidestand Relay and the Diode) are available from YamahaFred
