So i accidentally connected my battery in backwards and tried to start the bike... now i dont get any signs of life. Headlights dont turn on brake lights dont turn on doesnt crank nothing. Anyone ever done this and know the fix ? I checked the fuses and they seem fine i changed the ones that look odd and still nothing i even tried 2 different batteries. PLEASE HELP !!

 

Check the fuses *properly* - especially the 30A one between the battery and main fuse box. It's almost 100% a fuse (or a completely melted wire) because there's nothing digital between the battery and the headlights.
