Well, this is the situation.
Yesterday on the way to the XBR meeting, my battery died. I bought a new one which was dead by the end of the day as well. At the meeting, Hans and Johannes swapped the alternators of my bike with Hans’ bike. Today, my electric system still had a problem. I checked the electric components and in the end everything seems to be ok with a different battery. Did I buy a bad battery? A little trip this afternoon should clarify this.
John’s bike had issues as well which seem to be sorted at the moment. One thing is clear: it’s too late for Moscow now. I cancelled the hotel bookings and came up with a plan F or G: if everything works ok tomorrow, we try to go to Kaliningrad and visit Riga and Vilnius. A shorter program, but still entertaining enough.
