Dashboard condensation, maybe a new solution.

My Griso has been notorious re this problem for a long time. Riding North with the sun hitting the dash over my shoulder would quickly lead to fogging inside the gauge. The dash is quite easy to remove, but in no way would I consider opening it up.
On the back of the dash there are 2 spigot shaped air-vents, so I bought a small aquarium pump and some line and connected it to one of the vents, confirming air exhausted through the second vent. The pump pumps 60 liters of air in one hour. 2,880 liters in 48 hours (761 US gal). Parking the bike in the sun after that, there is no sign of the problem. Relative humidity in the house while doing it was just under 40%.
So I pulled the dash off my Breva as well. It has had minor fogging when parked in the sun. It has 4 spigots on the back. The lower one was not open, but air flowed freely through the other 3.
Done deal, not a lot of work involved, and a tool for the future for under $20.
 
Huh? I'm confused.

Do you have this pump connected all the time? How are you driving an AC motor with DC?

Or did you just connect the pump temporarily?
