Ducati 900 SS New Battery But Still Won't Start.. grrrrr!

Hi

I have a 1992 Ducati 900ss, which recently died on me (i.e. lost all power) in the middle lane of the motorway. Mildly scary but I managed to get onto the hard shoulder and arrange recovery. Couldn't restart it - ignition lights on and headlight etc, but just getting a 'click' when pressing the starter button, and no action at the starter.

This sounds like a relay switch or solenoid or something trying to do something but obviously not transferring the juice from the battry to the starter.

Have tried with a new battery just to prove it's not that, and same results.

Questions -

1. Why would the bike would just totally lose power like that?
2. What could be the reason for failure to start?

Any help much appreciated!  

Almost sounds like 2 problems that happened at the same time.
Loss of spark, and loss of starter.

Since gremlins usually only do one thing at a time, I'm going to guess that you have an electrical junction box (houses some relays, and fuses), and your problem is in there.
After all, it's the one spot on the bike that both circuits go thru.

Have you tried pushing it and popping it into gear?

Hope this gives you some ideas to look at.
