In fact, all the measurements are made with the R/R disconnected. I have not changed anything to the electrical system apart from an extra 12V socket (directly on the battery) for charging the cell phone with the engine off. But I did this last summer... Seems that I have to go to an electrician to have the bike checked but first I will try to have a measurement done at the terminals with the socket disconnected (and the r/r plug connected) to exclude that this is that shorts out.
Edit: it wasn't the extra socket... And my neighbors didn't like the fact that I was testing with engine at 4.000 rpm at 10:00 pm...
