[sawdoc1878]

bit of a mental block when it comes to electrics so please bear with me.  
 
CB650, just had a new battery,plugs,filters after her winter break. the bike starts when battery fully charged, and will run all day, battery charges when running, but as soon as the engine has stopped it wont start again, it appears dead. connectors etc not corroded and seem fine, THANKS and THANKS again

What happens when you hit the starter button? Do you get a click in the starter relay? Or do you get the click in the relay but it is the starter that doesn't turn? Or does both the relay and the starter engine work, and the bike doesn't start when you crank it?

possibly a gremlin in the ignition switch or kill switch?  mick.

i had something verry similar happen to me

and i thought the battery was going bad.

inside the left cover above where your tool kit would go and to the right of the RR "regulator"
there is a plastic box with a plug on top.  (this is your main fuse 15 amps)

mine appeared to be ok but touching it and it fell apart like wet ashes.

simply replace it and "viola!"  she starts every time.

   .35  fuse  beats a 35.00 battery
