Question about a joystick sending more than one signal when pressed
wongojack:
I ended up buying someone else's from-scratch, DIY rig. It's got some drawbacks in that there is no glass or bezel and a big --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules-- TV just sits in the display area. Its made of custom cut MDF so its heavy, and we had to disassemble it to get it out of the guy's apt, but this guy had some nice touches with custom re-wired speakers and a 4 player control panel. It was half the price of most kits I found so I just went with it. Maybe I'll post a a picture later (if I'm not too embarrassed at the giant TV).
Anyway, I put it together. Screws went back into place as they should. The 4 player control panel had a few points on it that came loose, this guy used IPAC4 but didn't put the crimps on the switches, just soldered them individually. I found the ends of the wires that came loose and re-soldered using the solder that was already there in all cases but one - which was a stiff copper wire that I guess is part of the daisy chained ground wire.
The fact that I didn't wire this myself is both a good and bad thing because I don't have to go through the time it takes to make the thing work, but I also have never wired a control panel, so I have to figure out after the fact how the thing is supposed to work in the first place.
Testing a few games and I discover that player 4 joystick up is configured correctly, but it does multiple presses when pressed. Pushing it in notepad gives me minimum two little 'y' s. 2 of the solder points I had to fix were for player 4, but they were buttons 1 and 4 which seem to be working fine.
Any ideas on what can cause a double press like that?

Ok, so a bit more testing and observation on this. When the joystick is pressed up I hear a click and a 'y' is typed in notepad. Then as I slowly let the joystick move back to its center position I hear an additional click and another 'y' is typed.
In game what happens is player 4 works fine until you press up, at which point the character moves all the way to the top of the screen and will not move back down. The character can move left/right and jump/fire, but will not move down.
I think that either the connection is soldered to the wrong side of the switch (always closed) or is possibly soldered to both sides, but I have no real experience with this. Has anyone ever seen this behavior?
Hoopz:
Can you post a picture of the switch so we can see it?
And when you look at the bottom of the joystick note that when you press UP on the joystick, the switch that's being activated is the one closest to you. It's backwards if that makes sense.

I'll get a picture of it it soon. The control pad was not built to swing up on a hinge, so I need to unscrew it and carefully lift it up. This requires another person to help as I'm pretty sure that I will pull more wires out if I do it myself. 4 players = a large panel, and its a bit of a rat's nest under there.
I was mostly wondering if I described the behavior - someone would have heard of it and be able to tell me what I'm looking for when I pull the control pad off.
Hoopz:
Check to see if the ground is attached properly and that the wire going to the I-Pac is correct also. The picture that I linked to shows which ones you use. Where it says "NO" means normally open and is the wire that connects to the I-Pac.
