Happ Perfect 360 and ground wiring problem

[Chiefy]

Hi all, I'm upgrading my Happ supers to Happ Perfect 360's and I've come across a wiring problem. When I only have the joystick for P1 wired up the cabinet plays fine (but with only one player). Then when I connect up the 5v/ground terminals to the P2 joystick the P1 joystick is always stuck in one direction. if i disconnect that direction wire then it will get stuck in anotehr direction, so basically when I connection P2 joystick all directions of P1 are always on.

The 5v to the Happ 360's are taken from a pc molex connector. Ground is also taken from the molex but I've also tried with taking it from the cabinet using a spare ground line off the buttons, no difference.

Could someone who understands jamma wiring explain what I'm doing wrong here.

Thanks guys!

ps. Think this is one of my first real posts My cabinet is a Metal Magnum, its a fully metal cabinet with a 26" monitor. Bloody heavy but solid when playing those fighting games.

As long as you're sure you've got the correct line for the 5v supply (the red one,) and the grounds (either black) and you have all the directions wired up correctly on both sticks, it doesn't seem to be the stick's problem, especially if you can swap them for each other, and both work fine while being the only one connected.  (Can you?  Maybe something's up with that second stick?  Hook it up as P1 if you haven't yet.)

It's not just one of...it IS your first.   

Check with Happ themselves if you don't get a better answer than mine anytime soon.  Which someone will probably give within the next 48 hours.

Yep, I've taken the correct 5v line (red one) form the pc molex. Does the ground connection have to be daisy chained thorugh out all of the buttons and the joystick? Will it make a difference if I take ground from the molex or from the original ground connections form the Happ Super joysticks?

I'll try swapping the connections tomorrow, if anyone else has an idea let me know.

Cheers.

Do you have separate 5V for each joystick?

[Chiefy]

I take two separate 5v leads from one pc molex connector. That should still provide 5v to each joystick right?

[destructor]

No. You must have 2 totally separate 5V.

[Chiefy]

Right okay thanks. Will do that tonight cheers.

Just out of cusiousity I thought that by taking two leads from one 5v supply this would be the same as when you provide voltage to several pc hard drives using daisy chained molex connectors.

You got me thinking so I just went out and checked how my P360's are hooked up.  Both P360's (I have 2) 5v and ground are connected together and then attached to a single 5v and ground wire coming from a molex.  So you don't need seperate 5v power lines. 

I had a 400watt PS that could not handle my cab.  It fried in about a week.  I replaced it with a 450 and all is well.

I played around with the wiring again last night and I agree with you. You shouldnt need to take 5v from separate rails off a PSU, you should be able to take it off different molexes that run off the same rail (similar to the way that one psu cable would power two hard drive off one rail).

So I hooked it up again and no longer got the directional problem, but now only one of the joysticks would work. If one was working the other wasnt, I would then reboot and then only the other would work.

Therefore I'd guess that the joysticks are not getting enough power. The psu is a cheap one and problem not very efficient when operating at high wattage. I'll replace it with an FSP PSU, lets hope that 350w is enough.

On a side note the 360's are the dogs danglies! Street Fighter II moves are so easy. Just need to find a decent stick for it now as the stick feels mega cheap.

Actually... the joysticks probably don't require much power... I use the 5V header on my IPAC to power 4 of them.... If 5V works on your PC and it does not behave funny (no weird crashes etc...) its going to be just fine for your 360's.

Yep... allthough try heavy duty springs... the really make a diff!

I think he can check joysticks with 2 separate 5V, I think this is no problem and he will know if voltage is problem here. Maybe his 5V isn't full 5V
Check joysticks with 2 separate 5V and we will see what next.

Last night I put a new PSU in the pc. Tomorrow night I'll rewire so each joystick is powered by a separate 5v and I'll let you guys know how I get on.

Thanks for the replies guys.
