Daytona not turning over - full battery

I’m sure there’s an easy explanation for this so hoping to get some pointers on what’s going on here. Battery is fully charged, fuel is full etc. when I click the ignition the bike literally cuts out and resets. It seems to take longer than normal for computer to go through motions etc and then once it’s finished the whirring sounds I press ignition switch and hear a click, and then all lights and dash power goes off and then comes back on and computer goes through start up process again. Any ideas?

Check your battery terminals. I've had this happen to me a couple of times in the past, it was loose battery terminals in both cases. Actually I use zip-ties now to secure them, as I've grown tired of having them get loose due to butter-soft battery screws.

If it's not that, then you probably have a short somewhere, or a bad relay.

How do you know the battery is good? Have you tested the battery with a load on it?

I've experienced the same issue, you need to take the battery to an automotive store to get it tested. Its may have gone bad despite showing proper voltage. Once you replace the battery, test the voltage at the battery terminals with the bike running and rev the bike to about 6k rpm. The voltage should not exceed 14.5V, if it does, your Regulator Rectifier is not working correctly and that is what is toasting your battery by overcharging it.
