CP Wire help needed

[Connorsdad]

Please help a noob with which wire to use to wire up my cp, I have wired it once and re-wired it again only to have a ground fault again 

I've ripped all the grounds out and I'm going to start again, could somebody give me an ebay link to the wire and QD's that I need please.
These are what I used originally:

single core

that is your problem.

single core wire doesn't have any strength. you bend it a few times and it breaks.

you need some stranded core wire.

I agree with Lilshawn about using solid wire, I dont like using it, but you can use it, many people on here use ethernet wire for the panel, and most ethernet wire is solid.
So, by ground fault what do you mean?
Are you loosing the ground (loose connection), or is the ground simply not working?
If it come sand goes, you may need to solder the connection points.
If it is missing on some buttons, you need to use a multi meter set to ohms (or resistance).
Place one probe on the first button that the ground wire from the keyboard emulator attaches to.
Then touch each button in the chain (ground wire terminal), when you read an open circuit (no or very high resistance) then you have found where your loose connection is.
You can solder it, or twist it tighter with pliers. If it is a crimp connector, try re crimping. You can also solder the wire to the crimp connector.

Thanks for the replies, this is the third time I've had a break somewhere in the chain so I'm determined to do it right this time. How do you put the 2 wires into each QD, 1 at a time facing each side of the QD or twist them together before inserting them?

As I said, noob here, before this project I could just about and I mean just about wire a plug

Please recommend an eBay link for the items I need, save me wasting more money/time using the wrong materials. Uk based btw. Many thanks.

Have a read here first: http://arcadecontrols.com/arcade_wiring.shtml

These guys sell arcade grade wiring: http://www.ebay.co.uk/sch/i.html?_odkw=&_osacat=3944&_armrs=1&_ssn=arcadeworlduk&_trksid=p2045573.m570.l1313.TR0.TRC0.Xwire&_nkw=wire&_sacat=3944&_from=R40

Single strand doesn't work well with crimps because the single strand does not compress.

Crimped connections work because the metal sleeve arms compress the strands together and the strands try to return to an un-compressed state.

The easiest way to get good reliable connections for a daisy chain is to buy a prefab one from Paradise Arcade (they have a GREAT pre-crimped wiring selection) or another arcade vendor.

If you want to crimp your own, stranded wire is a must IMNSHO and ratcheting crimpers are highly recommended for consistent results.

Wha what?!

IMHO = In my humble opinion

IMNSHO = In my not so humble opinion
(In other words, I'm right and I know it.)
