Hi, i have burned the shit out of my battery controller by keeping it open and touching one of mosfet control transistors (small 3 pin p-channel sucker) with positive battery terminal. Led indicators just dim constantly on 30% of light power, battery not detected, and so on.
Apart from the fact that controller is blocked i need to repair the circuit. I have tested most passives in-circuit. I assume that the resistors between source and gate of soic-8 mosfets were toasted as they were open. I assumed them to be 10kOhms. They were extremely small so i have made a ghetto fix. The problem persisted.
I am not sure WTF are those white-blueish-gray "5-6" components, you can see some of them in the back of the connector terminal.
And yes, i did actually scan the board
With the goal of identifying those tiny resistors. didn't help
And i did actually upload 2 insane high resolution files of 40mb each.
