Dashboard bulbs

Today I started the bike and all the dashboard bulbs in the background didn't work

, while the others dashboard bulbs worked (high-beam, indicators etc.).
I'm guessing the background dashboard bulbs are connected in line, so one is burn out.
Is it so?

not in line, BUT parallel! Better U check, is there 12V in base of both bulbs? Some voltage peak can burn both same time. That have happened to me. Anyway very cheap normal glass base bulbs....

Btw, does all other light(parking lights, especially) function normally????

Antti,
I haven't still tried the parking lights, but all others work well.
I never could guess both the lamps had been burnt together

No matter, I'll check them

!!

I've just tried to turn on the parking lights....
They work, but here it begins the mystery

!
The parking lights work and they work also the dashboard bulbs!!!!! But, ONLY with the parking lights on!
When the lights are on with the engine running (but also with the engine is off), the dashboard lights are off.
Could it be a switch problem?
Sunday, I glued the sliding plastic selector of the lights because it went broken.
Perhaps, some glue could do it?

Ciao

I think, U are in right way now. Next step is to check 100% that switch and U can use multimeter in DC Voltage scale to check output of light switch, that its function, like should. Follow 12V and at end You find, where that 12V stop. Anyway, be carefull to not to do any shortcuts with multimeter probes...

Surely U need wiring diagram to follow wires.

The only thing I made it was put some glue on the slider to fix it to the switch.
But, I realized that a little glue drop fell down on the switch.
So, I moved the slider to avoid it could lock.
Therefore, the only issue should be into the sliding switch.
Obviously, the slider switch controls both the lights and the dasboard bulbs, but is it possible the switch contacs for the lights and the dashboard bulbs are different?
Could I try some contacts spray or could I worsen the issue?

Those contact cleaners are safe to use in Your case. Dashlights function allways same time, as parking lights, so if U want parking lights work alone, then need some wiring mods, but its quite strange way....

I only want the dash bulbs work when the lights are on.
Perhaps, I spoiled the sliding switch...

Just a thought . You haven't washed the bike or been out in the rain have you ? My brake light was on permanently for three days last summer after a high pressure hose session. Once it dried out everything worked perfectly again!

No Rogero, I didn't wash the bike.
As I told, I thing the switch has been damaged by the glue.
Since I have another spare switch, I'm going to replace the switch.

If that glue have gone to switch, its, like "a resistor" there and then switch dont let current go via it, so propably You have lost that switch...

PS, Frankie, i send Personal Mail to You. I need Your help with one small Italian translation...
