Hi again,
thx for your input, after that I checked the battery once more and opps, its 95 – 97% so I got a new one 849:- at Batterilagret in Jönköping. It was two days ago and since that the AM runing without any problem at all. So the dealer (Gårdsman) will not have me as customer any more after told me “I have to change the mainboard”. Thanks :cheer: B)
