if you get excessive moisture in the clocks all sorts of weird **** can happen.
the most common is the indicators having a mind of their own, and comming on when they're switched off...
also, you can get reverse flashing of the tacho/clock (with the ignition in the off position, the tacho needle goes backwards a few mm, and at the same time, the clock flashes off altenately.)
the pcb within the clocks is really sensitive to condensation, usually, the condensate just collects on the inside of the glass, and causes no major issues...but if it gets bad, the pcb starts to become affected.
best cure is to vent the clock casing properly....and conformal coat the pcb on both sides.
these Itallian clocks really are a POS aren't they? :yes
I did hear that Piaggio were going to outsource to India or China for their new units...It'll be nice to have a bit of quality for a change :lol
