There should be no connection at all between ground and NO until the button is pressed.

Disconnect all wires from the button you are testing and connect the meter to the ground and NO connections on the switch. If you still register a connection when the button is not pressed, then you have defective microswitches.

I don't work in the professional arena like you do, but do defective microswitches happen often? Or, often enough that you suspect them to be issues?

blueboy:
unplugged and the buttons have no connection, but when plugged in they do...
I'm assuming this means somewhere a wire is touching another, but i've checked and don't see anything..

ANy ideas?

Thanks,
Blue

I think the next step, if you don't find any wires shorted in your wiring, would be to check for continuity between the ground connection on your Ipac and each button connection on the Ipac.  Do this with nothing hooked to the Ipac, there should be no continuity.

I've had microswitches with a intermittent connection on the NO when I press the button, so that if I hold the button it randomly rapid fires.  It actually happened on my joystick and it would not hold continuously in the direction of the bad microswitch.

Hmm...Really, i thought there would be continuity....
Perhaps i'm misunderstanding but here's what i did...


I disconnected s1 and ground from the ipac...Used a continuity tester on the ipac switches themselves, one end on ground and one end on s1...There is continuity here....I thought the button is what would make it so there isn't continuity and the button press completes the circuit..

Is my board fried?

Thanks,
