Hi spinal +
modern Gottlieb EM-Four-Player-Pins usually have two kinds of "Tilt" --- one is the (mild) "shaking the pin too much results in loss of ball in play" - the other is the (severe) "all kind of trying to cheat - banging on the machine makes the pin to (kind of) toggle-off the main-power-switch and toggling-on again --- all players loose all remaining balls --- starting for a new game is needed". The "mild" Tilt makes the H-Tilt-Hold-Relay to quit-pulling until the pin changes to next ball / next player. The "severe" Tilt makes the R-Hold-Relay to quit pulling --- we then must start a new game so the R-Relay is made pulling (again).

The "Abra ca Dabra" has no H-Tilt-Hold-Relay - it only has the R-Hold-Relay --- so Abra ca Dabra only has the "severe" Tilt.
When You wedge the R-Hold-Relay into activated position: You do not have the Tilt-Functionality. AND You may have problems --- You are playing and in play You toggle-off the main-power-switch - means You have "1,2,3,4,5 ball in play": You toggle-on (again) the main-power-switch and You cannot start a game by using the Replay-Button (But You can start a game by throwing-in a coin worth "One coin - one play started". To avoid this problem: Wedge the R-Hold-Relay into activated position - AND make its switch with wire-color-BL-WH, wire-color-OR-WH ALWAYS closed. THEN make an good description on what You have done to the pin.

(The written above is my interpretation on "Switch on Ball Count Unit / Switch on R-Relay --- shown in the schematics at 'E-14' ") Greetings Rolf

Hi spinal
The "Switch on Ball Count Unit / Switch on R-Relay --- shown in the schematics at 'E-14' ": When You wedge the R-Hold-Relay into activated position You then may manipulate the Switch on Ball Count Unit to be always closed (wrap a bare / naked short wire around the two solder-lugs of the switch). Pins in the arcade-rooms at the time had to be fool-proof - nowadays we own the pins and do not crazy things like pushing the Replay-Button randomly.

I agree with HowardR on "not having the pin - looking at the schematics --- impossible to predict 'everything' with 100% accuracy".

I do not recommend it - we could use modern Relays that do not get hot --- see
https://gfinder.findernet.com/public/attachments/40/EN/S40EN.pdf : First page shows 40.52 Relay , also page-2 (I own several such color-orange 40.52 relays - various voltages) - we can buy AC-Voltage 6, 12, 24, 48, 60, 110, 120, 230, 240 --- on page-4 we see 40.52.8.024.0000 is the relay for 24VAC (50 and 60 Hertz) --- little problem: Such Relays only have TWO switches - two Make-and-Brake-Switches.
To make an replacement of Your R-Relay (five switches): You'd have to mount three "Finder 40.52 relays" parallel. Finder is an Italian company --- in the USA You have http://www.ia.omron.com/products/category/relays/ . Greetings Rolf
