I was helping a friend from other fourm and was showing him how too remove a Ninty Joystick.

Well a Green Wire has came loose on my Metal DK3 Cp.

All my other Ninty Cp have this wire going from the Joystick too one of the sides on the cp brackets .

This one comes up from the back of the Cab into the cp.

I can up this back on my dk3 cp and start playing and the sound keeps cutting out.

I hit the cp in the corner where this wire is and the sound comes back...

I would guess this is a ground wire of some sort for the sound?

what do i have to do to get the sound to stay on?

I've tryed bolting it too that bracket it only works for soo long and then does it again.

thankyou too everyone that takes the time too respond.
 
It sounds like your grounds are daisy chained through the control panel. Are you sure that the wire crimp is still in good shape? If the crimp is not making a good connection it can temporarily lose connection as you are describing.
 
That Green Wire had came off the CP

I pretty much put it where all the other Ninty cp had this Green Wire.

Seems i can hear feedback sometimes when the game is'nt being played?

Should this be bolted down on the one side of the CP Brackets?


What Crimp are you speaking of OZ? Thankyou for responding so quickly.
 
If the ground is daisy chained you might want to do a continuity check on each ground while wiggling things around.
 
The green wire is the safety ground for the metal parts of the cab and in no way should be related to the speaker at all. The speaker wires are red and white and they go directly to the sound amp on the monitor. I would check the connections at the speaker, since it's close to the control panel hitting the CP could make the sound come on/off if the connection is poor. - Barry

Normally I would agree with you Barry, but the majority of Brian's games are Space Age Specials, so there is no telling what is going on with the wiring...
 
Well this DK3 did'nt come from Mark at Space Age.

It was an home made rewired for 2 different boards in the machine.

It does'nt use a Normail Speaker it uses a MagaPhone. Don'nt ask i don'nt have a clue why.

I have thought about Buying a New speaker for it but i just have'nt gotten around too it.

If it was that simple why did'nt the other oweners just do that?
 
Do you know if your audio amp board is okay? The only reason I ask is that my dk junior was wired to a pc speaker when I got it because the amp needed capped. I was lucky that they left the real speaker in there and once I fixed the amp the sound worked
 
I'm pretty sure they Green Wire is the problem.

I get alot of Feedback from that wire. I've tryed bolting it back down too the control Bracket but that only works for soo long and then sound goes off/ comes back with Feedback.

Kinda like a Radio Station coming and going..... With this game you have too push the Spry Button soo fast and move so fast.

Seems too be something is Interfaring with the sound.

I can hit my hand on the back of the machine and it will make a Feedback noise.
 
I kinda messed with this alitttle bit today... There is wires that goto the players start buttons and by pass the joystick? I wiggled those and i kinda got alittle feedback noise.

Then i noticed a white wire was off somehow.. I tryed putting that somewhere.. Sound worked fine for short while then went complete mute 99 percent of the time.

The other 1 percent there was a very quiet gameplay sounds.

If this Green wire is Daisy Chained like you say ? Where should be chained too?

Thankyou everyone for your help!
