But a short circuit seems pretty likely too me, you can check the high/low beam switch and wiring very easy, this is a good place to start. There is also the well know connector/ regulator issue, but in that case the high/low beam should not make any difference I guess
I finally discover the problem few weeks ago.
The stupid mechanic put the Givi crash bars seizing the loom, so there were few short circuit and afected the ECU. The store payd me a new loom and ECU and now everything is fine!
