Power Issue
I accidently went to fire up the bike with the battery tender still hooked up and it killed the bike, shut off all the electrics with the ignition still on. Now it's doing what it's doing in the video.
I had all the electrics on once, but as soon as I hit the starter, just went dead again.
I've checked all the fuses, battery connections are good. The battery tender keeps going from saying it's good to bad. Battery is likely the problem, but any one else have any insight before I drop £120 on a lithium battery.
