Day Dreaming ...
Anyone replaced one of these yet? A friend fried his accidentally and BMW only sells the entire fan assembly. I am looking for schematics or an alternative thermal switch for his perfectly fine (tested it) fan!

I haven't done any work aside from basic maintenance on an F-bike but I make my living fixing cars. Are you certain that the fan control thermo-switch is part of the fan assembly? I don't have an ST around to look at but typically the thermo-switch is either screwed into the radiator or, more commonly now days, vehicles simply use an input from the engine temperature sensor, the ecm then activates a relay for the cooling fan. (peeking at my 800GS I don't see a switch at the fan or radiator but again I'm not very familiar with these F-bikes yet). Is it possibly a relay that has fried and not a switch?
Let us know what you find and how you fix it.
