I read that there are/were some fake Shindengen R/R's out there, maybe yours was one of these?

Better regulator. People have had great results purchasing from this guys.

Found the paperwork , it came from motorsport electrics in Swansea all seems ok , will give them a ring on Monday, can these be tested to be sure that it is faulty , it’s only lasted 4000m ,

Is the connector melted at all?

I had to swap out mine with a new weather pack connector.

Will take it off tommrow and have a good look ,

Aye, as above, check your brown connector and buy from the States - have only had one of them fry the brown connector.

Well it’s good news , took it all apart and it was the wire from the regulator to the battery terminal that had snapped off so will put new end on and should be good to go , to many wires and not any room to cram them all in ,

There are a lot of fake mosfet type r/r out there. Buy an FH020 Sure it's not the stator?
