Thanks for sharing!!

cannot find....

I think yours charger is something like B6. Its usually inside positive and outside negative.

but the best way of course is follow the capacitor -ve pin to find which is negative la. Or you can use a multimeter to help you if cannot find.

inside positive and outside negative?

我搵到電容正負極啦, 但睇返個layout 好似同個插頭無關係..

C兄 係唔係插 12V 輸入的?
如果係既,我冇記錯正負錯左都冇問題的,同埋唔記得左好似分左咩直流同交流電...
真係唔係好記得= = 幫你唔到SORRY

最衰冇他錶係到...放左係地盤...
如果唔係就可以卡下我部差機條輸入線就知道了,不過我已經幫你問緊人了

已經知道了, 中間係正
你睇返塊板既電容已經見到了 都係岩岩人地教我先知^^

ho chi hai the opposite way. You can see from the board the positive terminal of the capacitor leg is connected to the upper leg of the socket.
