just as i decide to swap it the bike wont start. ive left the battery on charge overnight, still no joy. its not turning over at all. i have an uprated starter solenoid on it. sometimes i turn the ignition on and get nothing, other times i turn the ignition on and it all looks normal until i press the starter button, i get the click from the solenoid and then the whole dash goes blank. its like i have a poor earth or bad live connection somewhere but looking so far ive found nothing. any ideas pls guys? also, what is the small black box just next to the starter solenoid? it rattles and has an electrical connection. should it rattle?! cheers.
