When I insert ignition key, 3 lights in headlight go on. Plenty of battery. When I push starter button, click and all the lights go out. No cranking or anything. I must remove and reinsert key and lights go back on. I can kick start the bike OK.

Is there an easy way to check whether problem is in the starter button before I go to the starter & solenoid, as that is a bigger job.

thanx
