MK2 Schematics for coin door?

[Rulkiewicz]

I recently bought a gutted MK2 cab, it came with the power supply bolted on the floor, the coin box and the marquee light.  The marquee light words fine.  Now I'm trying to get the light on the coin box to work... it has a connector which plugs in to something, but the board that is plugs in to is missing.  There are yellow wires which connect one coin light to the other coin light, and then run down the wiring harness in to the connector.  I'm thinking I need to supply power to those yellow wires...?

Any ideas?

The transformer in MK2 had a dedicated 6.3V winding for the coin door lamps.  Those yellow wires should run all the way down to the transformer into a small, 2 position Molex connector (.093 pin/socket style).

There is a fuse for this output separate from the 120V output that was used for everything else in the cabinet.  Both fuses are installed in the metal box that the transformer is mounted to.  Check them WITH A METER (a visual inspection is not always accurate).

Manuals are readily available in PDF form and include a full cabinet wiring diagram.

Could you provide a link to the pdf?

Thanks.  However, I do not have that 2 pin connector on 3-4.  All I am left with is the 13pin connector that is connected to the coin door found on page 3-3.  Is there any way I can wire power to the yellow and yellow/white wires?

Ah, you're missing the main wiring harness?  Easiest thing to do in that cause is yank the two relevant wires out of that 13 pin connector (I don't like that connector style, anyway) and extend them down to the corresponding wires on the transformer.  You can solder/heat shrink, use wire nuts, or install some connectors of your own.  Other option would be to install a DC supply and run the lamps off 12V or 5V from the supply (select corresponding bulbs).  Since you have the dedicated winding on the transformer, I'd just use that.

I'm having a hard time figuring out where those yellow wires are supposed to go.  Attached are some pics, any help would greatly be appreciated!

The two wires coming from the coin lamps go to the two corresponding yellow wires coming out of the transformer in your last picture.  There's a 2 position connector at the transformer side.  Left of the picture.

Awesome!  Works like a charm, thanks a lot!
