I changed out the rollers and bearings in my Centipede's trackball unit today. When I reconnected it, I noticed that left and right movement was reversed. I took the unit back out and inspected, but could not see any way that I could have installed anything backwards.
After wracking my brain and doing a little research, I decided to just switch the wires on the molex connector and everything works again. However, I'm very confused about why it worked correctly before I changed the rollers and bearings, and would not work afterwards.
