Quesition on wiring and wiring with the Keywiz Max 1.5!

[rdowdy95]

Hey guys.  Just have to finish staining my control panel box and I am going to ready for wiring.  Here is my question.  How much do I need to strip/wire to stick in the .187 female quick disconnects?  Also do I fold the exposed wire then stick in the disconnect?

Next question is how much wire to strip to go in the actual keywiz max.  also do I just stick the wire in straight then screwdown the terminals, or maybe make a hook shape then put it in there.

Then last question.  I am wiring the 1st player 8 way joy along with the 4 way.  So I insert both of those positive wires into the keywiz's same terminal.  Same with free credit buttons along with the actual switches at the coin mechs.  But for the negative ground wires do I still just daisy chain all of those together and then run them to the negative terminal on the keywiz?

Thanks for the help guys!

Man you are loaded with questions there.   I'll see what I can do to help here.

The first thing is what type of wire are you using.  If it is stranded wire at about 20 gauge then there is no need to hook the wire.  Take and remove about 1/8"-1/4" and tin it if you want, solder the strands together.  If you are using solid wire then a hook might be necessary if the gauge is thin.  I do this when I am using network cable.

For the player one joysticks you have the right idea.  Put the same direction wires from both sticks into the same terminal on the KeyWiz. 

The free credit buttons can be done the same, one button for each coin mech and each set into one terminal on the KeyWiz.

The ground wires can be one or several loops.  I would use a loop for each section on the CP to make things simple.

That should do the trick.  Have fun and take it one step at a time.

What do you mean about the ground wires making several loops.  I only have one Ground input on the keywiz.  Is looping like dasiy chaining?

Yes.

What I was referring to is one ground wire going to the player 1 buttons and stick, another to the player 2 controls, and a third to the credit buttons if you want to turn them off and mandate inserting tokens.  You can add a buss bar for the ground connections.  One wire from the KeyWiz to the buss bar then branch off the buss bar to the different areas on the CP.

This way you can compartmentalize the CP into zones.  This allows you some measure of control over the CP.  In my case I want to have the ability to turn off the credit buttons so my kids don't have free reign when I am not around.  Rewards will be given in tokens.  However when it is party time I can open up the credit buttons for 'free play'.

Hey guys.  Just have to finish staining my control panel box and I am going to ready for wiring.  Here is my question.  How much do I need to strip/wire to stick in the .187 female quick disconnects?  Also do I fold the exposed wire then stick in the disconnect?

Assume you are using stranded wire.  Depends on the thickness of the wire you are using, and the size of the disconnects (red, blue, or yellow).  Generally, you want the wire to fill up the metal "collar" on the disconnect before you crimp it, but not extend past it.  If you are using small wire, you will often want to double or even triple fold it on itself.  If you are using multiple wires in the same terminal (daisy-chaining the grounds, for example), you won't need to fold it over, probably.

Basically, if you have a few spare disconnects, after you crimp two or three, you will understand what feels and works right.

Next question is how much wire to strip to go in the actual keywiz max.  also do I just stick the wire in straight then screwdown the terminals, or maybe make a hook shape then put it in there.

Very little, all you need is bare metal wire for the screw clamps to tighten down on.  Striaght in, no hook required.

Then last question.  I am wiring the 1st player 8 way joy along with the 4 way.  So I insert both of those positive wires into the keywiz's same terminal.  Same with free credit buttons along with the actual switches at the coin mechs.

Correct.

  But for the negative ground wires do I still just daisy chain all of those together and then run them to the negative terminal on the keywiz?

Yes.  What Kaytrim means is you can also run them through a loop.  Start at the KeyWiz GND terminal, daisy-chain to all the switches, then daisy-chain BACK to the same KeyWiz GND terminal.  What this means is that you can now have any single wire segment break in your GND wire and your machine will work like nothing happened.  Redundant GND paths.

Awesome start at gnd then loop it and come back and plug it in the same gnd.  Nice.  Very nice.  So to make sure start at the keywiz gnd, then daisy chain all of them together then when I get to my last gnd in the chain, then daisy chain that wire all the way back into the GND on the keywiz right.  Thats cool.

That was from therealbobroberts website, I can't take credit for it!  And KayTrim also has a good idea on using a separate ground chain on buttons you might want to disable.

You go directly from the last button in your chain back to the ground... not back through all the other buttons.  You may already realize this, but I just wanted to make sure.  "Daisy chan... all the way back" is what made me wonder.

  I really like the idea of being able to disable the credit buttons.  You could put a keyed switch in-line with the ground for those and then just turn on and off the free buttons with the key.

[Kaytrim]

On the credit buttons, don't make a loop. make a single chain with the on/off switch the first one in the chain.  If you want to make a loop take a single wire from the KeyWiz ground to the switch.  Then start your loop from the switch to the buttons and back to the same point on the switch.

Below are two images showing a ground loop switched and not switched.

Here is the complete circuit for the player 1 and 2 buttons and coin mechs.  Black wire is ground, green wire is credit/coin for player 1 and blue is for player 2.

Hey Kaytrim, Couple of questions.  What exactly do you need the wire I outlined in red for? And I like the idea of not having the kids run up the credits. This circuit doesn't allow any credits to be added unless the switch is on right? Do you have that hidden or keyed or what? 

[rdowdy95]

This is very nice and very cool.  I think I have seen those kind of switches at Radio Shack as well.  Very cool.  I would love to do that for my cab when my son gets older.  My marquee says free play on Saturday.  So I figure never tell him about the switch secrets, and then on everyday it is not Saturday he would have to use his own quarters.  Then on Saturday give him some free play.  LOL!  Make me some cash!

IG-88, the loop on the ground is extra protection against faults in the line.  This could be caused by a bad crimp or a break in the wire.  It can be omitted if you choose.  I plan on using a switch inside the coin door.  Seeing as the coin door is locked there is no need for a keyed switch though that is an option.  If the switch is on then credits can be added from the button or coin mech.  If you want only credit buttons or coin mechs working then connect the ground line to the mechs on the post opposet from the button ground line.  See the image below.

Cool. Thanks.
