Question About HAPP Trackball and Grounding??

[lettuce]

On the Happ trackballs you have a large green wire with a mounting hoop on the end which is for ground the trackball, i guess for static build up??, Is it ok to ground this wire to the trackball mounting frame??

Anyone?

On my MAME cab I just removed the wire and I don't use it.  Been working fine for over a year.

I just cut the loop off and put them in a spare ground in my opti pac but i guess any ground would do. And yes it is for static build up so i guess its worth doing.

p's The x  and Y axis were reversed with me( as oposed to above web site instructions)  for some reason maybe happ changed the design sightly..

It's my understanding that it's indeed to prevent static buildup, but not for the usual purpose (protecting electronics).  It's to prevent dirt/dust buildup in the assy. to help prevent wear.  Hook it up!

I ran it to the lug which was the common ground for my sticks, buttons and IPAC.
My panel is on it's third iteration now, with the trackball plate countersunk, but I previously had it exposed and the trackball plate would often give you a static shock if the ground was disconnected. Not a big deal, but the common ground made that go away.
