Wiimote Corrosion Fix
So the in-laws had a problem with their Wii and Mario Kart. The one controller won’t let the kart go forward.
So I got the opportunity to crack open my first Wiimote.
I admit I needed to watch a Wiimote teardown video on YouTube because I didn’t want to go breaking anything. Once the four screws are out there’s some pretty tough clips toward the front of the controller.
Using a plastic spudger is the best way to pry the two halves apart.
The problem was pretty noticeable right away. The 2 button had a fair amount of corrosion on the “pad”.
I’ve seen a lot of repair videos on YouTube and this was my first encounter with actual corrosion.
The pic is after a little work with the fiberglass pen.
After cleaning the pad with the fiberglass pen and cleaning things really well with isopropyl alcohol and some contact cleaner the pad looked a lot better. To make sure the corrosion doesn’t come back (or at least it doesn’t come back for a while) I loaded some solder into a some solder wick. Then the technique is to drag it across the pad and it tins the copper. I learned about this from watching GadgetUK164’s channel.
I think I’ve linked to it before.
The result looked great and the controller worked awesomely!
