Thanks for the explanation Neil. I'll have to have a closer look at the wiring diagram again when I get the time. This issue is the only one that bugs me with my 650, everthing else is a joy. I can live with it, but I will fix it in time. I do like the thermoswitch, and the fact that it'll run when the engine is switched off, dealing with heat soak, and as a result it has never overheated, by which I mean blown coolant out the overflow and into the bash plate, even on 38 deg days in single track. In this situation the fan can run for up to 5 mins after shutdown, stop for a few and it'll then run again for another minute or so. This I like, but I did buy a button to start it, so I'd like that to work all the ime too.
I found a pdf file on my computer at home that I must have downloaded from the TT site a while ago that is a photo essay on converting a KTM Kokusan to DC by "floating the ground". I can't find it on the TT site anymore, maybe because they now sell new stators?
I could send it on if anyone is interested.
Thanks Hair for the update, I guess TT can now sell a Berg stator?
Cheers
Steve
