The schematics use to be included at the rear of the owner's manual. It ticks me off to see they're omitted from the new manuals.
How 'bout this: Write to DUCATI. Express your concern and need. Remind them that it was part of the purchase of your "..1999 Monster" (or whatever). Tell them that a $13000.00 m/c should include it, and can they please email you one? Hey, what can they say, "No"?
Just what I wanted- with a little interpreting- it should do the trick.
Nice list of ducks you had. Had a '82 pantah myself- great little bikes- even today. Though I'm sure you understand when I say I would never, never, NEVER want to go back to Ducati electricals of those days!
