Need a bit more info to go on...

So you're saying:

- when in a single-player game, everything works OK
- when in a two-player game, Player 1 starts racking up points (more on that later)
- when in a two-player game, Player 2 works OK? (or haven't gotten that far?)

At what point does it start adding points? Before the ball is sent to the plunger? After the ball is sent to the plunger, but before hitting anything? After hitting a certain target?

Which point value is going (e.g., the 10's, the 100's)? If it's the 10's, then the 100's and 1000's will increment on their own as the score increases 10x, 100x of course.

If you let the ball drain, does it stop the scoring, or do you still need to shut it off?

As it's doing the crazy scoring thing, is the score motor running?

Did it used to work OK and this just started happening, or is this a new game you're trying to resurrect?

I have a Jungle Queen which goes into uncontrolled scoring from time to time because I have a sticky drop target that won't go down all the way once in a while. When it's halfway down it is making the scoring switch which is supposed to be momentary contact only but ends up being stuck closed in this state. Is it possible you are experiencing the same issue and confusing it as a 2 player game set up issue?

How frequent is this issue?

Have you put new rubber rings on the game lately?

Play the game a bunch in single player mode only and see if it surfaces there also. Shouldn't have a scoring issue that shows up only when you have two players punched up.

You own a Jungle Princess?

I am not sold on the stuck target-

Your saying the game plays more or less perfectly on player 2- that this never happens.

Then when you use player 1- it gets stuck in an endless loop racking up 10 points on the score reel until its unplugged.

Is this occurring ONLY when you hit a specific target? (and only in player 1)

Or does it occur when you hit any target with a value of something like, 50, 500, 5000 (not 10, 100, 1000). Because the 50-500-5000 score sequence typically (often- whatever) is scored through impulse switch stacks on the score reel. That is quite different from scoring 10-100-1000 which is usually accomplished without using the score reel at all. So my guess is its supposed to be scoring 50 (or some multiple of 10/100/1000) but keeps going.

I would like to know what triggers it- take the glass off and just hit targets until it happens, shut it off, start again until you know exactly what triggers it- its either going to be a single target, or any targets that share a score sequence.

We probably need a schematic...

Its odd that the player unit is influencing this- Find a schematic and just look for any relays/switches on or associated with the player unit that run into any type of score sequence or target- its really seems like its going to be there and not on a target- I don't see how a target knows if player 1 or 2 or 20 is playing...

who did it?
