I got a ‘76 Royal flush when I bought a house and the previous owner left it behind. I always loved pinball and now I am in heaven. But the thing is, it looks like the machine was hacked to play in free place by bypassing a switch on the ball # motor (I’ll try to attach a photo). As a result I’m thinking that the extra ball / replay function is not working. I hear the knock when I reach the # of points, but when the ball drains, it either advances to next player or when playing one player it just sits in the drain with extra ball light flashing.

So I’m wondering how is the extra ball supposed to actually work both in the mechanical sense and the game play sense. Is “replay” the same as extra ball? I think there is a difference between adding a credit and adding a ball, where the credit is a new game, versus adding a ball to an already existing game. So I want to clarify whether replay means adding a credit or adding a ball.

And also, I’d like to know whether there is a better way to put a RF on free play, so that all the functionality stays intact. Thank you.

Someone enlightened me that RF does not actually have extra ball though. I saw it in a mod in another post and did not realize it was a mod (see below)

Thanks for the explanation on how it works on games that actually have it. Can’t wait to get one.

The only other thing that happens, sometimes, is the light behind the white star-ish design blinks. But I don’t think mine was hacked to add a ball, i was just confused by the post where someone showed how he did it to his RF.

Thank you for setting me straight on the lingo. It is easy for me to forget that these machines hit the streets so long ago, it was almost a different world in terms of the rules and regs of games of chance.

actually i take it back, because i just remembered that RF has (i think) this 00-90 function where at the end of the game one of the tens will light up, i.e. 00, 10, 20, 30, 40, 50, 60, 70, 80, or 90. If the number that lights up matches the tens of a player's score then you are supposed to get a replay. This is one the F relay. The F relay does not reset itself, so the number that lights up is always the same, right now it is 90. but when i manually reset it at the beginning of the game, it will function and one of the random tens will light up. however, since the game is set to freeplay, i am not sure whether it works, and if it is the freeplay that is stopping it from resetting.

also, i swear i got an extra ball today, scored 80,000 or so and heard the knock, the ball was shot to the plunger, BUT the drop targets did not reset and the bonus did not count, i thought maybe the ball jumped over the switch between the drain and the plunger, so i lifted the playfield and hit the switch, and the drop targets reset and bonus counted. it was my 3rd ball on 3 ball play. after that ball drained, another one shot out to the play field and the ball in play 4 number lit up. i played that ball and it went to game over.

i get the knock

The credit wheel never moves, b/c one of the switches on it has been bypassed to put it on free play (See pic)

I will check again, i was actually just assuming it doesn’t move because in all the playing I’ve done it never appeared to change, i did manually change it once, and i think it gradually moved back to its initial position and never moved again. I will take a look to confirm

Can someone tell from these pics if the Credit unit mechanism is misadjusted. After I manually advance (increase) the credits, and restart a game it does reset itself; but it resets to a blank part of the wheel rather than to 0.

Also when I manually advance it , it appears to advance only about 8 units until the spring wire becomes taught and the post sticking out of the wheel hits the switch. This seems weird to me since the wheel has 15 numbers on it but it seems like the mechanism only allows it to advance 8 units.

The credit unit does advance (increase) when the requisite number of points are hit, although it is hard to tell if it is moving forward and back very quickly, as it is starting at a blank spot. The mechanism is firing for sure though when the points are hit.

I’m thinking the post on the left was bolted into the wrong hole?

If it were moved one hole over it wouldn’t get stuck on the spring and it would provide for a greater range of motion before the post on the right hits it’s switch?

Removed and moved the post, and moved the wheel, and it now works correctly!

Yes, I have it set now so that 0 shows at the restart. Also when I hit the requisite number of points it adds credits. Also when I hit the switch in the 2nd coin chute it also adds credits. And the when it is game over, and the score reel resets, it resets to 0.

Yes, it appears that although the credit wheel is now functional, it does not count down correctly. In addition, it does not add credits when I press the button that adds players. It only appears to advance credits when I trigger the switch On the 2nd coin chute, and gives two credits each time it is triggered. No credits added when I trigger the switch on the 1st coin chute.

One pic is with wheel at 14 (rod with white tip away from switch. Other pic is wheel at 0. Close up pic is wheel at 1.

Not sure what to make of the following: when I play in more than one player mode it adds a credit at the end (maybe the f relay is doing this?)(I still haven’t soldered the c points on the score reel circuit boards). It does not do this in one player mode.

It does not necessarily decrease credits At game over, but when I turn machine off and then turn back on, and then press the play button to reset, it resets to 0.

Disclaimer, there were a lot of different scenarios, e.g. one player or multiplayer; starting at 0, 1, 4, 15 credits Etc.; turning machine off or not before reset; and i was not tracking everything 100%

I love those device mock up videos, thanks.
