Yesterday the meter was even going to 18V and engine warning light went on with this high load.
Went today for a new HD unit and found out that the one which was giving to much voltage was not original HD but from Drag Specialties.
Now with HD unit (which was 4 times the price of the DS rectifier) gives good reading.
Wife now very happy, because she was afraid she couldn't drive the M3W Treffen next week.
Interesting. Please, if you can, post the DS part # as one to avoid. The H-D unit should be on the cheaper side as well but markups...
