i was starting the car this morning ,it fired a few times an now it has a gone dead. turn the ignition key and nothing. no electrical power to anything.

tried the fuses in the junction box and the starter relay. what else can i try?

i have 12.75v at the battery.
cheers craig

You need to go back to basics.
Is there power at the battery, decent connections, good earth, have you got power at the fuse box, have you got power to ign switch, from switch etc - no shortcuts really with electrics tho' sometimes the good old "wiggle everything & see if it comes to life" can work - unfortunately this approach doesn't necessarily tell you where the fault lies.

bikes have a "main fuse" which is seperate to the rest of the fuses - or usually is. check that.

have you done any work on it recently and maybe forgot to secure a wire properly?

When this happens on mine its either a bad earth or else what I have to do is turn the ignition on then unplug the small plug from the regulator/rectifier whichever it is that has two on it. Plug it straight back in then start engine. Dunno why it works but I know I'm not the only one it happens to.

it could be anything, as said go back to basics, even the most simplist of things. Do you have a spare ecu unit, if so try that.

one thing is. with ignition on and if i turn the light switch there is a buzzer sounding. what is it? but nothing else has any power.
