4 of Joystick GROUND wires are connected to each other, but not the rest of CP

[80sarcadegames]

As per the image below (see the GIANT YELLOW ARROW pointing to the red box on the left), my JOY STICK on the left has all 4 of
the ground wires connected to each other, BUT THE NONE OF THE JOYSTICK GROUNDS ARE CONNECTED TO ANY OTHER BUTTONS
OR JOYSTICKS ON THE CONTROL PANEL.

As per the link below for my "Project Anouncement" introduction (and see images below) this CP is something I purchase from
another guy on Craigslist so I am trying to "get this CP right".

As per DeLuSiOnAl's youtube video below, he says "ALL GROUNDS NEED TO BE CONNECTED TO EACH OTHER".  Doesn't
that mean that my JOYSTICK ON THE LEFT IS SUPPOSED TO BE SOME HOW CONNECTED (VIA GROUND WIRE) TO ANOTHER JOYSTICK OR
BUTTON IN SOME WAY?

In other words, don't I have to find a way to connect one of the GROUND wires on the Joystick on the left (see giant yellow arrow and red box) to another button GROUND WIRE or the other joystick GROUND WIRE???

In the photos below, are also photos of my CP which show that some sort of connecting box is used to help connect the wires
but the JOYSTICK ON THE LEFT IS NOT CONNECTED TO ANY OF THE TWO "CONNECTING BLOCKS", much less anything else on the CP.



Here is the "connecting block" (which by the way none of the joystick ground buttons are connected to, obviously).

(the tiny red arrows throughout the CP wiring diagram below are connection points that have not wire attached to them ie I have
to figure out which wire should go to them)



Here is a view of the entire CP wiring (you can see there are a lot of wires NOT CONNECTED if you look closely)




Is my joystick on the left OK the way it is as far as the GROUND WIRES are concerned, or should I somehow connect
one of the ground wires to another button/joystick ground wire on the CP?

the grounds don't HAVE to be all connected to another ground but it is the most efficient way of doing the job. I cant see exactly what is going on in those pictures but what I would do is daisy-chain grounds to all the buttons and joysticks on the player one side and then run that to the player one side ground on the ipac. Then do the same for player 2 side. I hope that makes sense.

[Loopey1]

Big Question in my eyes is why the hell are you using barrier Strips? That just makes a mess outa everything IMO.  Mount the ipac right in the Center of the CP (Hot Glue if you have to)

then run each wire to its switch. Nice Simple SHORT clean wires. Run P1 Grounds in a daisy chain on ALL the P1 controls and Joystick, to the Ipac P1 Ground, then do the exact same thing for P2, but ground it to ipac P2 side.

As above,
But are some of those white wires going into the connector strip burning or is it just shadow from the flash?
If it is burning you want to chop the end off and reterminate them checking tightness.

Are you talking about this area? Lol.
I don't know what the *&^% that is but this CP is not connected to power nor is the iPac 2 USB connected to anything.

Thanks for all your help guys.

Note: I just noticed while viewing my MS Paint image / layout of the wiring diagram that the GROUND CONNECTIONS (BOTH PLAYER 1 AND 2) have no wires going
into them at all!!

Question: What is the negative affect on your CP if you forget to ground a button or joystick or NONE of your buttons or joy sticks? Will any of those said buttons/joysticks work at
all?

[Titchgamer]

Ide be worried if it was connected to the mains! LOL

As for your question.
They wont work simple as that :p

rip all the ---smurfing--- wiring out.
buy a cheap jamma loom on ebay, cut jamma connector off
wire the swtiches to the IPAC, jamma loom comes with ground loop.

all the grounds on all the switches for all the buttons and sticks should loop together.

I'd have to agree -- even if you don't go with a Jamma loom - pull all of the wiring and redo it -- With all of the loose wires I see in the pic it's probable that some of the grounds are not complete circuits so will not work (one or more of the loose wires is probably the other end of the grounds you say are not hooked up ) Rather than take the time to figure out exactly what is what it's easier to just start over !! (pull all the wiring and hook it up from the begining so you know what goes where and how the grounds run - from your drawings it looks like you are missing the wire that runs from the encoder ground to the ground loop of the joystick and it is probably one of the loose wires but hard to track it down in that mess !!

IF they are not grounded the circuit can not complete so pressing a button will do nothing ! If the grounds are hooked together and never connected the entire circuit will not be able to complete and none of the buttons will work.

Is a Jamma Loom the same as a "Jamma Harness" (see youtube video below):

Is this considered the equivalent as a Jamma Loom?

Do I need to buy a JAMMA board to go along with a Jamma Harness/Jamma Loom?

[Malenko]

harness, loom, all the same thing.
Thanks for quoting my giant text a buncha times though.

get this: http://www.ebay.com/itm/121753778577
cut off the black thing (aka edge connector)

JAMMA boards are actual arcade games, so no. Just buy a harness, cut the edge connector off and re-use the pre-crimped wires. Throw away those extra screw terminals, you dont need them either.

Have you looked at any project thread on this site at all and saw how the IPAC2 is wired?

Thanks. I will buy that ebay item.

As far as IPAC2 wiring videos, are you talking about these?

[JDFan]

Nope - just get the harness wire the end with the quick disconnects to the various buttons/joystick directions - cut the wire from the other end (jamma connector) and place that end into the correct spot on the encoder -- rinse and repeat for each button/joystick direction and once you're done with them all it will all be wired correctly and ready to go ( any unused wiring can be kept for other uses (ie. the power wires, molex connectors etc.)

Thanks. When you say "encoder", you mean the IPAC2, right?
BUT the BLACK wires are "looped together" and go to each button's and each joystick GROUND connections?

[JDFan]

Thanks. When you say "encoder", you mean the IPAC2, right?
BUT the BLACK wires are "looped together" and go to each button's and each joystick GROUND connections?

Yes on both -- the encoder would be the ipac2 if that is what you are using and the jamma harness will have a ground loop connection that has several quick disconnects wired to a single long black wire and you use it for the ground side of all the buttons and joystick switches and then use the labelled wire for the other side of each as labelled on the harness.

SO each button switch will have 2 connections going to the ipac - 1 for the ground (which also goes to the other buttons in a loop) and 1 from the NO (normally open) connection on the button switch back to the specific input on the ipac2 (ie. joy1 up goes from the joystick up button back to the joy1 up connection on the ipac - etc. etc. etc.

It's really pretty simple once you get going - just go from one connection to the next and you'll have it done in no time.

 

[Malenko]

you're over thinking this. getting the jamma loom/harness is just so you dont have to crimp wires, and you can color code if you want.

all the grounds "loop", just go take a look at any project thread

here's my old project:

Thanks. The problem is that I will have to CUT OFF the disconnects on this harness/loom because the previous owner of this CP decided to, what looks like "permanently crimp" on some sort of quick connect which will require that I cut off each quick connect end on the loom/harness because only a stripped wire will be able to be "pushed in" and "crimped" to each connection on the buttons and joysticks.

Looks like a new "How to wire a control panel" video update is in order!  (It's on my list of things to do in 2017).   

There's no such thing as "permanently crimped" when it comes to those connectors and the microswitches.  They are probably on there really tight.  Just use a pair of pliers and yank them off (carefully).  Unless they are soldered on of course which I doubt; that's a different thing altogether.  A closeup pic would help of just a sample microswitch so we could see.

Thanks DeL!
I will post a close up.
Last night I tried to pull them off but I was afraid of breaking the button/joystick connections, but MAN those are on tight!!   
I will do as you instruct and carefully hank them off with a pliers.

This is what they are EXACTLY:

my gawd a pair of pilers and yank away
they will come off
just grab the plastic hood not the wire
and pull them off

^This -- or get a small screwdriver and slide it into the back part of the crimp and bend them upward to loosen then slide off -- that is what Quick disconnects are made for they slide on and off if they are too lose you can crimp down on them with pliers to tighten but they are designed to come off so just use something to slide them off or loosen first then slide.

You'll be cutting off the other end of the wires from the jamma harness not the qd end (whole reason for buying the harness was to have the QD's already crimped to the wire not to cut both ends off !!) otherwise no reason to get the harness as you could just use wire
