happ trackball 2 1/4 Centipede up down movement problems

Installed a new happ trackball unit in my Centipede Cabaret. Had no up or down movement so looked on the net and it said the green and yellow wires need to be swapped. I did that and now it work OK except sometimes it doesn't go up or down when I want it to....slow reaction sometimes. Sometimes it kinda just stays where it is and I have to spin it harder to get it moving. Other times it works fine...
anyone had these kind of problems with a new happ unit??
 
Did it also do something similar on your old one? Board problems, or bad connections at the board can do the same thing.


Had something similar to this happen recently and it ended up being a board problem.
 
Trackball

Three times when I ordered a new trackball for a centipede and mounted it in the same position as the original. The up and down was wrong and the left and right was correct. I just switch the plugs on the trackball and everything was fine. I did not need to remove and relocate the pins.
 
the old trackball was working fine. Just rough and loud as hell. But no problems with it stopping.
I was told to crack it open and see if there is any dirt or maybe clean and rotate the bearings.......
I guess I'll crack it open.
It's brand new though, don't expect to have to fix it before using it..
