Hi Steve, Would that coil situation be the same for an E-120 Machine. I have plugged in all the male plugs into the pin banks and I get nothing/no response from the selector buttons. I even went as far as changing the entire selector button component with new plugs and I still get no response from the selector buttons. So I wonder if what you mentioned will be the same for the E-120 machine when it comes to the common connection and electromagnets. Any thoughts?
Thank you - Jamie

I'm quite sure the F-120 had small numbered stickers on the bottom of the mechanism, to match the numbers on the cables, that fall off with time! If I remember right, I found them floating around and one or two still attached last time I was in there.
If the harness hasn't been removed from the machine, you should be fine, but beware that Aaron H. and I determined that if you swap sides by accident, the selector mech won't work at all; IIRC 6 of those plugs have an extra pin that is the common connection for all the coils in a section, and if you swap the halves the common pins will fit but won't connect to anything, so no power at all to the selection electromagnets. (This discovered on an AMI F, but I believe the G has enough in common that this will still be true.)

Well, it wasn't quite as confusing on a 40-selection machine, and the
80
and 120 selection 45 mechanisms just use 2 or 3 of the 40-selection selectionlever assemblies. The picture in the manual shows the plugs and their wiring path to the Jonesconnectors, with this legend: "Position of plugs shown as seen
when
lookingfrom front of phonograph and beginning at front left hand corner with plugnumber 1." Then it shows the Selector Bank Plugs is this
order:
[ ] #7 [ ] #8 [ ] #9 [ ] #10 [ ] #11 [ ] #12 [ ] #1 [ ] #2 [ ] #3 [ ] # 4 [ ] #5 [ ] # 6 So using the length of the wire bundles as a rough indicator, this shouldhelp getting each plug in the right jack.
