The issues continues, disconnected all fuses (fuse 1-7 + ABS fuse + main 30 Amp fuse) as well as disconnecting the 12V socket, ctek eyelet, heated grips, xenon lights and it still drop faster than if the battery would have been completely dis-attached from the bike.

I now ordered a new original battery, will arrive today or tomorrow hopefully. Need to get the bike out of the garage and get going so if the problem remains I'll have to take it after the season.
