Hi guys, any help would be appreciated! I have a 2003 (53) model and when I turn ignition on I get nothing Kick start and runs fine, no indicators until I throttle it. The back relay I think (white box by rear mid guard) buzzes like mad until I throttle or touch either brake. I installed a brand new battery, Turned ignition on and had 'N' come on ok, started fine. Then stalled when I put stand down And now nothing when I turn ignition on and same scenario of starts fine etc. any ideas? Cheers
