probably starter relay. clicking it it trying to throw over the relay switch, remove it if you can and bang it on the ground and put it back and try it. if not try banging it with handle of screwdriver or something you can get to it with. let me know what happens.

Were you having trouble with the battery before this incident? If not, then charge the battery with a charger...NOT a trickle charger...for 12 hours. After this, check the voltage with a volt-ohm meter, it should read 12v -14v. Install in the bike, connect and check it again with the volt-ohm meter, it should hold the same reading as off the bike.

Try to start the bike, if it starts, check the battery again, now it should read 14v or a little more. Turn everything off and try to start it again. If it starts, the battery is still good but don't leave it on like that anymore.

If you get anything less than 12v after ther charge, the battery most likely has a dead cell and needs to be replaced.

Testimonial: "Thanks much - very helpful"

Check your altenator connections, you have an intermittent charge circuit that is allowing the battery to run down over a period of time.

Testimonial: "I will check that out and let you know. Thanks for the effort"

SOURCE: Battery charged, Start button does nothing, Turn Signals Flash

It does sound like your alarm is still on. try manually turning off the alarm. Please post theresults. Hope this helps.
