early bally coin door socket E120-162

[Mr Pinbologist]

This might help you understand whats going on, i've taken your pic from your first post and modified it slightly  

The 2nd lug, its whole purpose in life is a tie point for a diode on games that have a lamp matrix type setup, so it has NO connection at all to the barrel portion where the lamp fits in, hence why your lamps dont work! Notice in the pic i have indicated on the drawing of the socket(s) where the wires would go.. notice the green/red lug goes directly to the barrel portion whereas yours is insulated.

You would really have to solder the green/red wire to the barrel as i have indicated in the pic below.. this would work BUT.. as pointed out by ballywannabe it might need to be insulated from the coin door where it screws on.

that's exactly what I figured but wanted to check. Thank you  wry much for the confirmation

No worries, glad to help

Green/red on the inside lug and Yellow/black on the outside lug. It's the same on Wiring to the coin door lights on all 4 of my Bally's.

that's how I wired mine but not lighting. I even reversed just in case and a few other configs with no luck.

Nice soldering btw

Just check you actually have power then.  Using the socket you have, put one wire on the central tab, the other on the barrel and the lamp should light (don't have the socket attached to the machine).  Alternatively, put your multimeter on AC and check for around 7v.
