What do you mean by extra credit?
And how does being on free play mess it up?

Quoted from Knxwledge:By extra credit, I mean that when special is lit and I hit the appropriate target, the game awards me another credit (as if I put in another coin), and it advances the credit reel. I should have said free credit. It being on free play isn't the problem by itself. It becomes a problem when the game gives me a free credit and increments the credit reel. The way I've set up free play, I have 1 switch permanently closed when the credit reel is at 0 credits. The free credit(s) I get from the special messes this up.
The only radio plug/jones plug I see in the back is the points scoring one (approx. 10 rows and 2 columns), which doesn't have anything to do with special, if I'm not mistaken.
I'm still not seeing what in the world your issue is here.
On a credit unit there is a zero position switch that opens when the credit reel shows zero. That opens the circuit to the start button and doesn't allow you to hit that button to reset the game. There is also a max credit switch that is closed until the game reaches max credits. That opens the circuit to the credit unit step up coil and doesn't allow the game to add more credits.
When you set up a game for free play the zero position switch should be closed at all positions on the reel, not just zero. So you're saying that at 0 the switch is closed and you can reset via the start button, but you can't do that with the reel at any other position? That makes no sense because the switch in its normal state is closed at any other position than 0. I'm not sure how you mangled the switch to do that, or why you would do it in the first place.
You want to set that switch so it is permanently closed in all positions and you're done. You'll get credits for specials and you can still start the game even with no credits on it.

I do not see a Maximum-Switch in the schematics --- here the Zero-Switch. Greetings Rolf[quoted image]
There is one. Every credit unit has one. You need to find the step up coil for the credit unit in the schematics and the max credit switch will be in that circuit.

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[quoted image]
15th position switch is what you're looking for. It's right there.
