Party Zone
Bally, 1991Can anyone post some good quality pictures of the J115, J120 and J121 GI connectors on the driver board? I'm trying to figure out what someone did wrong and it looks right to the book/schematics but I still have an issue or two. I know my J115 is not wired right for sure but I'd still like to see pictures of all three if anyone can please take the time to do so.
Thanks,

Yeah that helps a little but now I'd like to see a picture of whats correct, would Gilligan's Island be the same thing only maybe a different color wire was substituted from the factory maybe ?

Quoted from johnwartjr:The wire colors are standard on all WPC pins for J120/J121.
Kinda what I thought but looked into my Gilligan last night and something's different, including wire color and position of the wires. But basically the positions of the wires should be the same, correct? Regardless of color. I think I can figure this out based on that confirmation.
Another stupid question: The 115 connector with the yellow wires, Why is the wire from say pin 8 going back out and back out to pin 7 ? Was this to disipate the heat or something ? Why not just jumper it on the back of the board ? Or put the wire into just one pin and not the other ?

This thing is a mess. Someone hook me up with pictures of all three of those connectors from another Party Zone, PLEASE. I'm looking in Gilligan and its totally different, Funhouse is about the closest thing I've seen but I want to see what another actual PZ is supposed to look like.

In that photo, the wires on pins 10-11 on J121 are swapped. However, that won't matter to the connection.
From that thread:
"The other thing wrong in the pic is J120 - the white/yellow wire should be on pin 9, not pin 10 so it's piggybacking on the return."
I can try taking pix tomorrow for you if no one else has done so by then. Have a New Year's party to throw...

Quoted from Dayhuff:Not familiar at all with this game. Should the RED lights be on all the time or only during a multiball ?

No, only during Big Bang, not in attract mode.

Thanks Viper. Very interesting. Your 115 connector is not jumpered from pin to pin. Is this actually from a PZ ? You also have different tracers on those yellow wires then mine.

See now I've had someone else tell me that the red lights are on all the time and never go off, but the regular GI lights go off during Multiball. Mine I have yet to see anything of them turn off during multiball, but everything works 100% during the different GI test and they all turn on and off with each test so I dont think there is a board/triac issue. Very strange.

Yes - this is from a PZ - just took these photos for you...
Running diagnostics I don't have any issues - all lights work as they should.

Yeah my PZ runs perfect in the test as well. I've seen the regular GI lights flash on and off during a multiball but not stay off while just the reds are lit. Is it possible to get a three ball multiball going on this game ?
Thanks for the pics and all your help so far, you've been a huge help !!

You can take a secondary harness from a TZ, and put it in a PZ, or pretty much any game with a WPC-89 board. An original PZ would have all yellow / yellow with white tracers at J115.
Those colors don't look original to any WPC games, it's possible someone built a new harness, or replaced the wiring in the harness, too.
J115 and J120 both clearly are not original. But, they are pinned correctly.
Quoted from Dayhuff:Should the red lights be on during the attract mode ??

The entire playfield lights-up in red ONLY after the player has achieved the BIG-BANG jackpot. This is obtained only when you are in multi-ball and only after you have filled up with ROCK-IT FUEL, and then fired a ball up the ROCK-IT RAMP. Once you score the BIG-BANG the illumination of the playfield is purely by red lights and the Jimi Hendrix Experience song 'Purple Haze' is played for the duration. There is NO other way to have purely red lighting.
If you need any more images of the connectors on the WPC board, let me know, but i think the images here already are higher definition than i can offer.

The Party Zone is only a 2-Ball multi-ball. Im pretty sure that it is not possible to induce a 3-Ball multi-ball. If you did manage it, you'd be playing a different game.
Originally i thought that a 2-Ball multi-ball was short of the mark ... but it isn't. The game would be a bit crowded with all 3-Balls on the playfield at once. Even with the 2-Ball multi-ball things can get a bit crowded, and it isn't that easy to keep the pair of balls alive.
Multi-ball can be achieved in a couple of ways, and to earn a 2nd or 3rd multi-ball in one game is fairly easily achieved, (unless the Captain B.Zarr saucer shot throws the ball down the guts).
If anyone has worked out a 3-Ball multi-ball, i'd be interested to try it, but i think it would be overkill on The Party Zone machine. To make the existing multi-ball experience more interesting i add 2 or 3 different balls to the machine, (like 1 silver, 1 black and 1 golden ball).
When the Big Bang is first lit and you make the shot up the ramp with the first ball, is it supposed to wait for the second ball to go up the ramp too before it gives you the jackpot? So in other words are BOTH balls supposed to sitting at that back VUK to score the jackpot ?

Laser Beam has it right. No three ball multiball only two (though the game requires three balls to be installed.) And the red GI only comes on in Big Bang. Mine is non-fliptronic and I'm running M-3 ROM code (patched for LEDs non trivial task.)

Anyone have an idea of what's the point of installing 3 balls?
I have a very clean example here at home, if anymore pictures are needed I can help you guys out.

Short answer, yes.
Long answer, there are two switches at the end of the ramp - sw 41 for the back ball popper and sw31 which is the back ramp switch. After you shoot the first ball up there it sits in the popper and waits until sw31 is tripped to award the Big Bang. Now I know on my game both switches work in test but I've never gotten the Big Bang (I'm not that good a player!) - closest I came was locking one ball before draining.
I should also clarify something that I had forgotten - the regular playfield GI lights turn off and the red playfield GI lights come on for every visit you make to the Cosmic Cottage (Party Animals, Party Monsters, Party Dudes) besides the Big Bang.

Finally got the RED light issue figured out. Probably half of the red condoms were missing so it appeared that the regular GI bulbs never went off, when in fact the lights that were still on were actually more RED lights that just didn't have the condoms on them. Simple fix and I'm back in business. Thanks.
