Hi EMsInKC
I do not see a Maximum-Switch in the schematics --- here the Zero-Switch. Greetings Rolf

Hi EMsInKC
I do not have the Big Brave (1974-05) - I do not have the Duotron (1974-09) - but I have the schematics. "Out of Sight (1974-12)" I do not have - I have a partial schematics. Greetings Rolf

Hi EMsInKC
in my schematics "Duotron" I do not see a "15th Pos. Switch". Therefore I am not 100% sure about wire colors and so feel uncomfortable talking about the switches on the Replay-Unit.
I also wonder about the OP's solution of "Free Credit / Free Play". Greetings Rolf

Hi JudeRussell
thanks for Your post-14 - someting new to me ... "J-Add-Replay-Unit-Relay" and THERE in the wiring is the "15th Pos (Replay Unit) switch". Greetings Rolf

Hi
if I would do something - I would do as frenchmarky suggested in post-24. Rather easy to do and can be taken away by an latter owner --- easy to document.
IF (if, if) I would like to try - does this works ? - I maybe would try "wiring I show in the JPG".

One thing that is never discussed - shouldn't be an switch on the Replay-Unit to open and stay-open Positions 10,11,12,13,14,15 to make the Coin-Lockout-Coil to quit pulling ?
The way it is wired in the pins : Replay-Counter (lets say) is in position-12, a coin is worth 5 replays - throwing-in a coin makes the Replay-Counter to step-up - BUT ONLY three steps (reaching position 15: No more credits added). Greetings Rolf
