Couple questions: is your timer reset? Is your score feature disc reset? Try resetting those manually then trying to start a new game.

Things are pretty hectic right now, sorry for the delay, but score feature is a trip relay, correct? If so, check the hold switch on the relay and make sure it changes state.

If shutter doesn't open, is red button relay engaging on initial start relay pulse?

Yes. It allows you to put in more money at the time when the feature flashes on the backglass. It plays only for odds. If you start a game and have a good one going but your odds aren't high enough, you can feed it to get better ones, theoretically. Typically, the feature doesn't enable until your odds are relatively high, so for me, the stop and shop feature is a bit of a waste - but I could see how it could vacuum a few more nickels out of people.

It will be after the timer unit steps beyond the step where you'd expect, so step 4 if before 3rd. Not at game start.

It locks it out right away - the relay is a trip relay, and the NC switch is the signal that the relay has not tripped. Unlike a hold switch on a momentary relay, which continuously provides power until another factor shuts it off.

If the score feature unit is below the fourth step, the feature isn't available, so it locks it out right away.

But as soon as it trips, the path is no longer active.

It depends on the position of that score feature. If above step 4, then it follows the second path, and will trip when the timer hits a particular position.

If below step four, it trips immediately, and the NC switch should open preventing the coil from frying.

Check that switch over carefully.

Before fourth selector lock relay has to trip and that one switch you've circled has to be making.

Everything else is the same for every other step.

Could be! The timer only steps when switch 2A is closed on the lifter. But the relay has to trip first.

Yes

Well, first, why isn't the motor making a full rotation of the cams? With the game off, can you manually lift a ball easily by pushing the bar on the right side of the lift? (Don't get your fingers caught).

If not, then the lift needs to be adjusted to allow the ball to drop properly. If it does, then you have a problem with the hold switch for the motor on the motor cam. Not enough current is flowing through.

If it keeps lifting, that is because the playfield is lifted and the lane switch is not being pressed.

I do not own a Beach Time, but by any chance was this game set up to give 5 plays for a quarter?

My brain is slow this Friday. Sorry about that - these are on the replay cam index. I thought stack 16, at a glance at your pic, was for adding credits. My mistake!

So, the adjustment of those switches is pretty critical. Normally you'll get low pays or other problems if it is not right. Make sure they operate just like in the manual.

Scoring operates like this:
1) Search disc turns, making connections with various search relays if a ball is present at the rivet as the wipers travel on the search disc.
2) If three or more search relays (for the most part) are engaged at once, the search index coil pulls in.
3) Switch 17B energizes the replay cams index, and as it rotates, the game will award replays based on the replay counter unit as well as the number of bumps on the cam that awards the replays (13).

Not also that the backside switch (13) has to be adjusted exactly as in the manual.

So, in my experience, if the search disc is not -stopping-, then you have either:
a) dirt on the search disc
b) dirt on the slip rings
c) dirty wipers
d) a warped search disc
e) a search index relay switch that is not adjusted properly (it takes a delicate touch to adjust these, as you probably know).
f) dirty search relay contacts.

Somewhere in there is your problem. Once the search index is pulling, then you might have issues with the amount you earn, but at least the replay cams index should pull and things should happen. If they are inconsistent, you have a 'flaky switch', though in this case, a switch might be caused by any or all of the above.

Hope that helps, but if not, I'm sure someone else will be able to get you to the right switch more quickly!

Does the search index ever engage? There is a resistor that uncommonly fries or becomes disconnected. It must be in working order to hold the search index.

As to the picture, there should be a piece of fish paper between the two sets of switches. I'm not sure I understand the question. The NC switch should be on a second stack (right beside the first). Check the picture in the manual to see the layout.

OK, in response to your question - no, I have no idea why there are wires on the other switch.

They didn't move that stack over to the wrong side accidentally at some point in the past did they? Check the wire colors to make sure (if you haven't already).
