Gottlieb - Score Motor.JPG

#1 4 years ago

trying to understand a score motor on a quick draw i am looking for 4c so it is the stack of switches
on the right side( A) is closest to the bottom of the cabinet , so when looking for 4c does 4a start
on the left of the stack or the right ,if someone could post a pic and highlight it that would be even better

This will help.

4C only tells you which switch stack the referenced switch resides in.

4 is the respective corner mount and C is the main cam level of the cam assembly per the picture that Oldpins posted above.

You figure out which switch to look at by the type(normally open, normally closed, make/break) and the wire colors at the solder tabs.

This is in contrast to most Bally and Williams score motors, where the schematic tells you which cam the switch is on, and then the level it is on, meaning you can go directly to that switch and don't have to try matching up wire colors, which on older games can be pretty badly faded out.

The Operator Manual (for 70's games) or the card on the inside of cab (for older games) describes which switch is for what, by position (e.g., inside switch, 2nd switch, 3rd, etc.) instead of by wire color. So it is possible to just look it up (even though it's not directly on the schematic).

This is true. You just hope that card is there for the older games.

I would guess that Gottlieb used the platter type motor to save space, because the reel type that Bally/Williams used does take up room. But they are far easier to work on, you can see every switch clearly, whereas the Gottlieb motors, it can be tough to see those A/B level switches at times.

2 on one side of the score number the
Rest must have fallen out this motor is the

For this game it will be in the Operator Manual.

Depends on how you wish to use it. The playfield assys are the same (unless that's an era where Gottlieb printed the actual name under the score apron, but they are still plug compatible). Option settings are probably identical.

But the Relay logic related to player's and reset sequence are quite different. For 2 player games, Gottlieb used a Trip Latch (CX) 2nd Player relay for buying into a 2 player game. But for the 4 player games, they used a Coin Unit (stepper) for 1 - 4 players. The player units are similar but feature different cam arrangements and again, come into play when you are looking at the score reset circuits. So, if you are working on Ball or Player Change problems, the circuit is completely different.
