JC, if you have power at the starter relay but the starter will not engage, that indicates that there is a problem with the ground portion of the starter relay circuit. That includes the light green/red wire coming out of the starter relay. That wire goes to the neutral switch. The neutral switch must be closed (ATV in neutral) in order for ground to be completed to the machine frame. Check that the wire is not broken and that the neutral switch is closing when the machine is in neutral.
