 Hello All
  New to this board and this hobby but did once rewire a pinball machine with a magnetic reed cheat switch in the NCO club and have a bit of an old school electrical background from the military, I am the latest owner of a bally 955-27. I have a feeling this machine has been passed down through the years with each new owner preforming some new modification to at least give it the appearance of a fully functioning machine  I intend on checking the entire wiring harness as soon as the schematics arrive. Does anyone know the significance of the 27 in the model number , are there 27 design changes hence the 955-27 ? or are these models based on the 955 base . I see bleed off resistors on some but not all of the relays, are some missing or are these the lower voltage relays .  Will any 955 wired coin hopper will work on any 955 machine or must it be for a 955-27.  I have a feeling it is not the original hopper .  And as long as I am on a roll ,does anyone have a coin hopper for sale for a bally 873
 Thanks and hello again

Welcome to the Bally EM form.
Typically machines will have 4 to 8 resistors.
Post a photo of the machine when you get a chance.
The attachment is from a list of Bally model numbers.
As you can see the number after the dash in most cases represented a casino the machine was sold to.

Check to see if your hopper has any numbers ascribed or written or it.. They should match your games tag  I have had games where they didn't match but still worked   Best bet is to see if it works or host us a picture.. Usually hoppers for a different 955 won't work in another. That goes for all Bally EM Slots.. There was no universal wiring, but it could be a simple as the plugs are wired a little different. Same color wires, just in a different pin location.. You will also see that not all games used the same wire colors. If they ran out of one color they would sub out a different color on the next one..

Hello Lee

Wows that's  fantastic to know!  I guess for tax reasons they need to
account for every machine and who it's making money for as well as
any custom bells and whistles .  Photo ? Sure thing !

Hello Amechanic   

The hopper had numbers in marker long since rubbed away
so I cannot read it all but If I had to guess its ??976? t 56.
It also had 2 orange wires shorting against the rack rail
  2 shorted relay blades  , a bad diode and 1 loose mystery
wire off the Beau plug ,oh and one loose terminal in the
Beau plug itself which is also missing both its index/contacts pins
which I have jumpers on for now till I get a new beau plug

  Yes I have started to noticed their creative wiring practices
 I will solve as soon as the schematic arrives and I begin
to learn the theory of operation of this gadget
but if its just a re wiring of a hopper from a 955 to a 873
 and that's it ,that's not too bad with a wiring diagram
