Hi,
have you checked the pick-up on the flywheel (RPM sensor)?
I had a similar problem on my 906.
Ciao

Did you check the quality of the gasoline after you winterstop?
Is the fuelline and filter clean?
Succes :confused:

7.6 volts over the coils while the starter is running is a very low measure... also 11.1 is not good... maybe some trouble inside the main switch (key lock) that you can test close to the fuse box.
In this case, an electrical bypass on the wiring can solve the trouble

Thanks guys for the info,

I've already checked the fuel and asume that's not the problem because I rode for 20 kilometres before she died on me.

The pick-ups are checked. They give a signal/pulse of 80 to 90 mV but I don't know whether thats enough. There resistance is low compared to the workshopmanual (220 Ohm) but both give an exact measure of 99 Ohm.Thats to much of a coincedent, so I asume there working ok.

Before I can do a electrical bypass I need some clear shedules because I'm no electrical genius. I understand that John Slocum made such a shedule in pdf format but I'm not able to download it. So if anyone could send me shedule that would be great.

regards Remko

Remko,

disconnect the orange leads to the coils

connect one to a relais (normal 4 contact car relais you can get everywhere)

isolate the second end of the orange cable (it`s not needed)

run a wire from the battery or starter relais (with an inline fuse) directly to the relais (this will give you full voltage back)

make a cable to connect the relais to ground (the frame)

make an Y-lead to connect the 2 coils to the last free relais contact.

that`s it.

Maybe you have problems with wiring connection: there are two plugs you must ceck: the one out from the main switch and the other from the engine stop in the right handle


and here are the suggestion to restore the main switch

"I hope I can suggest you something about ignition switch:
0)ENSURE YOURSELF TO BE A GOOD WATCHMAKER (or to have a spare part aviable!)
1)Disconnect the switch from the main electrical plant
2)Remove it from the steering plate, so you can work on your desk
3)You can see three little plastic grapple in the bottom cap
4)Open it very slowly and take care not to loose springs, balls and nuts (they are very small!)
5)Clean from rost and dirth, lubrificate with special white grease
6)Re-assembly everything (this can be very HARD!!!).
7)be careful in putting the balls in their right place

Hope the next time I'll be able to put images in the site, so I'll show you how to build a real bypass relay

I fixed the link to the wiring upgrade. Sorry about that. The wonders of computers!!!

The link to the instructions is:

You can even search for a couple of ducati performance units by pedercini, that are the same sold aftermarket for newer carb engines :thumbup:
However, here's a link for a good electrical bypass
