Do you have the Kuro 787-8 add-on with your MSFS 2020 installation? I had the older version and it appears that’s what caused the problems I experienced with the default 787-10’s electrical system. I removed the 787-8 from the community folder and that solved the issue.
I haven’t tried installing the latest version of Kuro 787-8, which I believe is 2.01(??) but I’ll wait and see if others experience the same problem with it.
@Michael7778145 , if that’s the case, could you please mark one of these posts as a solution to this problem so that other people having this issue can quickly find the solution instead of the usual situation, where someone new asks the same questions on this thread, every three months.
yes its worked the Kuro 787-8 add-on was the problem of battery toggle switch once i updated the new verso of Kuro 787-8 add-on its was working fine
