I will use an alternate base but the problem is that charging points circuit is short can you give me a trace of initial points. I mean which is the charging ic on board and what is positive point from ic. If i had another board i will surely trace this problem. I hope you understand what i am trying to say.

Hello

I want to know the charging jumpers ways of this jeck because positive point have damaged during heat gun proccess. i want to know the tracing of negative and positive points from ic or capacitor i will be thankful to you.
