Grounding cable

[Stokers]

I'm putting my Astro City back together, and i've been reading one of the many threads on grounding...but i'm still a bit confused.

Firstly I'm planning to swap the 2 prong power cable for a proper earthed one, attached to the earthing screw on the back of the control panel. I'm looking at the grounding points / wiring diagram and I think i'm missing a cable.

So from what I understand, the grounding points inside the cab are

• Coin mech
• Coin mech door
• Cash box x 2
• Front screw (in front of PSU) x2. 1 from the coin box and one from the power panel.
• There is a dedicated cable that runs into the control 'holder' to the right coin chute screw
• Left coin chute to control panel hinge screw

However on my cab, have a ground cable in the control holder, but it doesn't have anything attached to it - I think I'm missing this.. https://www.ebay.com/itm/234275892113

Also I have a cable from the front screw to one of the nuts holding the kick plate on



Apologies for a possibly stupid question, do I need this cable to safely ground it my cab? I'm reading quite a bit about people getting shocked by the control panel screws

If you’re using a isolation transformer for the monitor and psu then I doubt you need a earth,hope this helps.

I'm going to be using an Airlink transformer

My plan on this was to swap out the 2 pin standard japan mains cable to one of these (a pretty standard modern Japanese desktop PC or laptop cable):

I was going to lop off the kettle plug end, wire that into the existing mains filter area and then connect the earth wire to the cab's earth pin.
That way I get earth like on every other cab I have.

Good plan? I've not actually done it yet.

As for the control panel cable, I'm definitely missing the same on one of my cabs.
So long as the rest of the cab is suitably earthed I'm sure you'll be fine. It's probably only there for static buildup from 1990's shell suit jackets.

Yeah that's my plan, although i've bough an earthed US power cable..which is the same right?

That's good to know, the only issue is I exclusively wear shell suits in tribute to the 1990s.

Yeah I think they are the same, probably just different wire insulation colours inside!

Pics or it never happened
