My selenoid was clicking and i thought it was bad because the starter did nothing. I took my buds solenoid off his 400 and the same clicking. tHe battery is full i even tryed to jump start it but nothing. then i put a test light on the battery then the seleonoid then the other side while pressing the start button and all lit up. then put the light on the starter wire connection and it lit up too! but nothing from the starter. Can they just go out that fast? i rode it into my mechanics garage he was lightening the flywheel and installing a clucth and it came back clicking. My hair is falling out please help!

 

The clicking relay, is almost always a sign of a bad battery or connections. The only way to prove a battery is good, is have it load tested. If the battery is good, then look for coroded connections, or loose connections.
