Easy little test to do. At the solenoid disconnect (unplug) the yel/red and green/red wires. Now make up 2 jumper wires that go from the battery positive and negative. Connect those 2 wires to the terminals where you took off the yel/red and green/red wires. There is no polarity so either wire on either terminal. WARNING: the engine should spin over. Be sure the bike is in neutral. Reference the picture on the first page of this thread. Post #4 if it helps. Does the starter kick in and the engine turn over?
