[Ducati] Light no light !

[Doug Barnette]

Not the most technical post you'll ever read....

A few weeks ago I noticed, during my pre flight, that my front brake lever didn't actuate the rear brake light while the bike was running (04 999 mono). When I turned off the bike, but left the key on, the rear brake light would actuate. Then with out any inspection in a day or two the whole thing went away. 

Now then,.... Friday afternoon I took a solo sprint out for a late afternoon ride and didn't notice anything until around dusk. At that point I began to get high beam flash's from some on-coming cars. It took a few flashers for me to realize it wasn't them warning me about the police or a dog in the road, but rather I had no head lights. 

So I rode home holding the high beam trigger on the left bar, which still worked and believe me it was a pain. The high low switch didn't work at all, nada, nothing. 

So Sunday I took the fuses out, they were all fine, and then I checked for a loose connection, nothing.  Finally I took the bar switch apart and looked inside to see if the high low switch might have come un-soldered. That three wires looked OK except for a couple of tiny black marks on two of the wires that didn't look like they were shorts, but suspicious. The next thing is to check the low beam bulb....Right. 

The turn signals work as do the brake lights and rear running lights, the license tag light ...Oh, and the center windshield parking/running light works too.

I have a shop manual and have poured over it to find anything that might give me a clue. Anyone had both beam's stop working except for the high beams passing trigger?   Any suggestions.
