I washed People yesterday evening using coin operated pressurized mini-wash, it was -3 C outside. Came home without problems.
I have de-frosted the ignition key hole using WD40.
This morning I wanted to go to work and could not; it was completely dead, not even sound from the starter relay. However, horn, light and LEDs work normally, so does the speedo needle.
Considering that everything was fine until yesterday evening, I guess that either micro switches behind brakes froze, or kill master switch froze, or there is still problem with ignition key assembly or the side stand is frozen or something else. I should have moved it to sun this morning but did not and left it in shade, went to work in a cage. It is just a bit above freezing during the day, so I hope it will defrost. My gf comes from work around 4 pm (2 hrs before me) so she will try to start it. If not, i will let it sit for a day more, because if it is not frost-washing related, it has to be something completely unrelated to this that happened in the same time...
