recently I bought another non-running VX Li+ in Switzerland and brought it with a trailer to my home in Germany.
On the motor controller circuit board 5 fuses were blown and I replaced them all. After that the scooter MC started running again and I got a "go". The battery cell voltages were also still mixed up as it arrived like weed and turnips. I then recharged single cells. When I plug the scooter now into the mains I hear a relay clicking but then the dashboard does not start working but the battery fans do. Scooter seems to charge in the background without the working dashboard. When I turn now the ignition key on the dashboard starts working and shows to me the charging current and all charging values normally . So than the scooter balances the battery cells for hours. When I turn the ignitionkey back during balancing the dashboard stops working again and after some time the fans of the battery also stop working. Means the scooter stops balancing/charging in the background. If I turn on ignition again the dashboard starts again but shows no charging/balancing anymore instead the service lamp ist on.
That doesn't seem to be me like a big failure but what can that be and where can it be ?
