I haven't used my wiimote for 2 years and found the battery leakage in it a few days ago.
It doesn't work now Although I have deassembled and cleaned it.
I meassure the volatage on the PCB, there is 3.0v power into the PCB from the batteries but it seems there is no power supply for the IC chips.
I have no idea about the power supply circuit on the wiimote, does anyone have the experience about this kind of problem?
As long as your wii turns on I'd say don't bother. Just buy new remotes. Plus new ones with motion plus builtin are coming soon. Just toss the old in the trash or ebay them. It's not worth it. You will spend more time and money fixing them then they are worth. Just be sure to mention this problem and say spare parts only when you ebay them so nobody thinks they are new or gets hurt.
