Wii White Wireless Ultra Sensor Bar

Upon receiving the Wireless Ultra Sensor Bar it would not turn on. I tried new batteries, but it still wouldn’t power on. I inspected the device further and noticed it had terrible battery corrosion on the battery contacts. I cleaned the corrosion but again it still wouldn’t power on. I decided to disassemble the Bar and inspect further. Once it was disassembled I noticed the wire connecting to the left battery contact had severe corrosion on its solder joint. I cleaned the joint and then put new batteries in and it finally worked. Aside from the initial power issue, the device works great.

this is great now no wires hanging everywhere
