| Regulator
I've just had a similar experience - the rev counter jumping up and down - but only when I had the indicators on. Then no juice when I came to restart, just the solenoid clicking.
Turned out to be the regulator/rectifier and therefore no charge going to the battery - as the battery ran low the voltage drop was causing the rev counter to wave in time with the indicators.
New Reg/Rec is about £85 from a Ducati dealer - less from a non-franchise supplier (they're in the free Busters glossy in MCN this week for under £60 I think).
