what servo amp for happ hack?
Brian74:
So I went to my local dealer and got a happ 4 speed. Switches were bad but went to the shack and got new ones. So I have it hooked up for the most part. The the wires are hooked up between the amp and the donor wheel. Until I get my other ps, I have a 12v dc ps to try to see how it works. I try to adjust the pots and the well goes left and stays there as I turn things up. I used the logitech software and tried the action buttons. It works but it seems weak, which Im guessing is because the ps. It still goes to the left, and sometimes to the right. What do you guys have your pots set at??

Most of us are using 12v power supplies in place of the logitech one.
The wheel is probably going to the side because the input wires from the logitech board are backwards. (it's centering feedback working in reverse)
What the pots on the amp do are covered in the servo amp part of my momo hacking thread linked above.
You should really read through all the threads we linked above. This isn't plug and play stuff.
You're in for plenty more problems that will require tweaking to fix.

So your talking about the wires that go to the ref - and + ? I have been reading stuff on here and on 2 other forums.

Yes. For some reason they need to be hooked up backwards to what seems correct.
When most people do this hack, the wheel pulls to one side when they first hook it up.
It's centering feedback trying to work, but the wheel is moving in the wrong direction.
refers ref - and + and see if it centers instead of "uncenters".
Also one of the pots on the servo amp adjusts the bias side to side. That can also make it pull to the side.
Don't remember which one it is, but it's covered in servo amp part of the momo hacking thread that I linked to above.

Yeah, I reread your post and its the test pot.
