To verify the potentiometer is working.

Power off and disconnect from the A-Pac
Hook a multimeter to 1 and 3.
Set to Ohms.
Watch meter as you press the pedal. Does the reading increase/decrease?
The reading should stay pretty steady -- if not, find the two terminals that maintain a steady resistance reading and call them 1 and 3. Verify that readings vary when connected to 1 and 2 or 2 and 3 and the pedal is pressed.

I've never used one, but it's my understanding that the A-Pac shows up as two gamepads. 
Check to see that it's showing up in windows under game controllers before messing with MAME.
You should be able to calibrate the axis and see them move in windows.

i see one gamepad and i am not able to calibrate :hissy:

If this helps, I have this one and some more expensive ones. Anything helps though when you have none.

On the test tab, is it centered (doesn't see it) or off to the corner(sees it as a min/max)?

Do you have another pot to try?

Have any resistors up to 100k ohm? You can use them like a pot dialed to that value to trick the board. (connect one from black to yellow, maybe another from yellow to red on the diagram)

ok looks my a-pac was a dislexic version because it seems backwards from the diagram above :banghead: Look at pics.
1. does it matter on the potentiometer what the tabs are connectted to basically from diagram the 1st tab and the last tab are both hooked to the ground from 1stplayer to 2nd player on diagram so from diagram im not sure which is the ground. Still need to get meter to read but its a brand new pedal from HAPP.
