Found out what the problem was... the Regulator / Rectifier!!!
It is fried and the connections and wires are toasted, literally!

Lucky I didn't open the carbs, just needed to turn on the heated grips instead.
Can't complain of cold hands at the moment...

Anyway I got a new VR today, prepared the yellow wires, on both sides. then noticed an extra wire on the other connector. :slap: can i find any more appropriate smilies (or un-smilies)?

I have now have a partially modified VR for a later model bike! Aparently It will work, and has been cross bred before. But there is no way I can do it with the enormous collection of totally inappropriate connectors I have in my electrix box.

So early tomorrow am I will be going shopping not to work... tonight I will sleep.
