I purchased a bike and it had no keys so I installed a switch for the ignition. The bike powered on but when I went to hit the start button there is a click noise near the battery and the bike loses all power and will not turn back on unless I disconnect the battery and wait a few minutes and then reattach the battery.

  • This implies you did something wrong when installing the switch for ignition. I would suggest you review the electrical wiring diagram for your bike and see if you have connected everything accordingly. I'd be tempted to check your ground connections.

  • Check that the battery terminals are tight and not corroded. Sometimes a weak connection will source enough voltage to light the lights, but will fail when you press the starter. Apr 10, 2019 at 17:54

I've experienced similar issues with a weak battery connection as the_storyteller noted in the comments. The draw from the ignition turning over will cause a loose connection to sever.

I would also check the charge on the battery if that fails. Could be there isn't enough juice to turn the starter. Then I'd check the ignition electrical connections. Then starter.

Also. Make sure your kill switch isn't hit.


<-check kill switch <-check connections on battery terminal as the_storyteller's suggestion <-check electrical connections / starter <-check battery charge (or charge the battery some)

  • Let us know how it goes too if you can. It's always cool to know what it works out to be. Apr 11, 2019 at 23:02
