I have a customer with an AMI G120 that someone unplugged all the selector coils under the mech. Unfortunately, the manual doesn't show which plug goes where and I have two bundles of cables numbered between 1 and 12. Does anyone have a clue how they go? -- Paul Howlett Pinball Paul's 703-361-0420
Paul. I had this issue once before. I think I determined what goes where using the length of cables. Longest to furthest etc. After each plug in I tested making a selection. A bit of trial and error but doesn’t take long. I’m in the building Friday and I have a 120 parts machine and I can check for you if you can wait until then Regards Rick On Wed, Mar 6, 2024 at 8:08 AM Paul Howlett via Jukebox-list < jukebox-list@lists.netlojix.com> wrote:

Been the proverbally there, done the proverbally that. : -)Let the wiring harness be your guide. They line up pretty well.One caution you probably already know, is that those little roundplugs aren't keyed very well. Make sure they are all going in with the proper orientation.
I can't believe that they 24 identical plugs with no markings on the selector On Wed, Mar 6, 2024, 8:40 AM Jukebox Repairman via Jukebox-list < jukebox-list@lists.netlojix.com> wrote:

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.

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.) --> Steve On Wed, Mar 06, 2024 at 01:38:39PM -0500, Paul Howlett via Jukebox-list wrote:

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?

It is quite likely that the situation is the same for any AMI 120 of this design. All this is from dim memory as I don't have time to look it up at the moment: On the 120s, there's two rows of 60 selectors (one row for A side, one row for B side). Each of those rows is split into 3 sections of 20 selector magnets and fingers each. If what's below in this email is correct, they're numbered like: Left half harness -- Right half harness 7 8 9 10 11 12 7 8 9 10 11 12 1 2 3 4 5 6 1 2 3 4 5 6 For the momen, concentrate on the bottom row. The harness is divided into two sections, but the magnet banks are divided into three. So, adding L and R designations: L1 L2 L3 L4 plug into the leftmost bank L5 L6 R1 R2 plug into the middle bank R3 R4 R5 R6 plug into the rightmost bank 5 pins of each plug are connected to individual magnets. In each set of four, 3 plugs have only 5 pins connected, and the fourth has the 6th pin connected as common. For this example, we'll say the leftmost one in each magnet bank has the common connection, so L1, L5, and R3 have common. That might not be the correct position in reality, but works for illustration. If you have the harness halves reversed, R1 (doesn't have a common connection) will be plugged in where L1 is supposed to be (where the pinbank has common wired to). Same for all other positions where commons are supposed to be. Further diving into my cobweb laced memory, I'm pretty sure the pins that would carry common on the harness' plugs are not populated, and the 6th contact on the magnet-assembly may not be populated in the jacks where common is expected either. I.e. you may be able to figure this out visually, without even a voltmeter. Probably could have written that shorter, but I don't have time to edit it down! :-) --> Steve
Thank you - Jamie
