Trackball Not Recognised (Windows & Mame)

Vicious Burger:
I have a Happ trackball in my CP connected to the Opti-Wiz with an adapter cable from GGG. Optiwiz connects to PC via USB. There are a pair of green wires that come off the trackball and join together at a crimp connector,which I assume is a ground wire,(isn't ground usually black?) If this is the case, where should i ground it? The PC is inside the cabinet,should i run a wire to the PC case to ground it,or somewhere else? All my other controls (joys & buttons) work fine,they have all the ground wires on them,and are all connected through the Ipac4. Spinner is USB.

I checked with my multimeter that power is coming from the optiwiz,and it is getting 5v through the adapter cable. I'm not sure how to tell if its a grounding issue or if the trackball is knackered

Black is not neccisarily black, alot of times it is green.  I have not used the Opti-wiz but I think you should connect the ground it is as well.  On GGG website http://groovygamegear.com/webstore/index.php?main_page=product_info&products_id=260  in the description it says that it has  Connections provided for 3 buttons, 3 axes, +5v and Ground.

I'm pretty sure that when it says ground,it means for the cable that comes from the trackball. There are three 2-pin cables on the adapter cable. 2 of them (4 pins in all go to the x and y axis pins (according to Randy T) and the other go to 5v and ground. I'm pretty sure that the only grounding point on the optiwiz.

mlalena:
Just to specify a point:
The 2 green wires on a Happ Trackball are a ground for static electricity buildup from the trackball.
You should ground this green wire so that the static doesn't burn out a circuit board, but the trackball should work without grounding.
To verify your trackball is the same as mine, if you take apart the trackball these green wires should lead to a copper foil near the rollers.

Sorry I missed understood,  as mlalena stated this is correct.  As I took a look at my Golden tee setup and they are infact grounded to a grounding block in the cabinet.
