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?

Not often... but you can get a bad batch sometimes.... In this case it was worth checking to make sure.
What I don't understand is that he says none of his buttons work unless he holds down the first six and then all the others work.
Blue... If you checked the continuity of the buttons and the wires from the buttons as far as the IPac, and with them disconnected from the IPac you got no faults. Then the only logical place left now is the IPac itself. It could be a faulty one. There's really little more we can do to help.
Contact Andy by email and ask his advice.
When you do get a solution, don't forget to let us know what it is.

Do this with nothing hooked to the Ipac, there should be no continuity.

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,

It sounds like the board, there should not be continuity between the switch terminals and the ground. If there were the switch would have no way to stop it, the switch when "open" keeps there from being any connection, it doesn't actively change anything, a Normally Open switch at rest is like having nothing between the two terminals. When you depress the switch it makes contact inside and is like having a wire straight from one terminal to the other. If you are waiting for a response from Andy you could actually test the Ipac this way too. Remove all the wires and switches from the Ipac and put a wire in the ground terminal, with the Ipac hooked to the computer make contact between this ground wire and the switch terminals one at a time, if you do this with notepad or something similar open then you should get keystrokes on each contact, if you do, then the Ipac should be OK.
First and foremost, I think it's time to ask Andy.
Good luck, and definately report back when it is solved.
P.S. when quoting make sure to type your response after the "[/Quote]" box it makes the response much easier to find.

Can you drop me an email and I'll try to help. As has been mentioned, this is likely to be a ground connection which is broken and only made when those 6 buttons are pressed, indicating a wiring error.

blueboy:
Just for the heck of it, I rewired all the grounds, using new wires and new connections..
Still the same....
It can be any 6 buttons pressed and then the rest of the buttons/joy's work like normal, literally any 6.
Thanks for the help....
I'm at a stand still.

Andy fixed it!!!!! ;D
Was a simply uninstall of an item in device manager....
And to think, I rewired all the grounds :banghead:
Ohh well, lesson learned.
Thanks for all the help!!!!
