Gixxer k7 battery constantly empty

Evening zsm, Unfortunately I had a bigger problem with my 600 GSX-R k7… From the beginning: About 4 weeks ago after a long drive at the traffic light the gear-km/h display stopped. Shortly afterwards it went out. Battery empty… My friend took it and changed the Lima controller. Without improvement. Then the message LiMa burned through. Since the company has made good experiences with Limas from the accessories, I decided to do so. After a good 5 days I was allowed to w I wanted to start again and Zack battery empty. However, I don’t think it was the Lima because it didn’t go out during the ride. Now I thought that during the last tour I was only driving on battery voltage that hit the battery. 3 days ago new acid battery bought and drove again. Today then again… battery empty. Since I didn’t get another week at m a gixxer wants to wait and he wants to lose Euros I turn to you. Lima and battery can be excluded or? With crawl current etc I know myself so zero. Electrical was never my territory Has the k7 than larger sources which could draw electricity? Jmd had the same problem? Hope to answer numerous and helpful ones. Greetings
