I just acquired a Sky Jump and agree, it’s a great single player wedge head. You can strive for a high score or specials but you have to be dialed in to get both. A great nudging game, so I have the tilt a little loose to have fun.

Love that shot from the left flipper, off of the number 7 Drop Target, ball continues up, past the Pop Bumpers, through the top Roll Over number 6.

This is the set up on my Sky Jump.

Agreed. A few times I’ve had it clip the 7 target, up the 6, down the 4, then drop down left for the 1 or 2 or 3...sweet.

I accidentally sold my Sky Jump and still miss it.

I have a question. My Sky Jump only clicks when the tens reel scores, no chime. It’s supposed to chime, right?

If you haven't serviced you chime unit, the plunger is likely gummed up from the foam used as a cushion from the factory (and stuck in the coil sleeve). Disassemble and clean plunger with alcohol, and install a new coil sleeve. I use door silencers for the padding when replacing.

(And in case you're a newb, the tens-unit is the smallest chime of the three.)

Thanks, I will check the chime coils and assemblies once my wife is done playing it!

I sold my SJ the same way I sell most of my games: I don't have them advertised and am not intending to sell them. However, someone sends me a pm and says 'I'm interested in your game' and then they offer a reasonable price. Very often, I think about it overnight and then accept the offer. In the case of Sky Jump, I took it to expo (not for sale) and someone came along and offered a couple of hundred more than I thought it was worth. So I thought about it overnight and sold it to that person. Now I miss it because of fond memories I have playing it in college. Even now, I would say that about half of the games in my collection are vulnerable.

Hoping to join the club soon. This machine is a lot of fun.

Maybe it's different Down Under. You know, kind of like the way the water in your drains swirls in the opposite direction.

I agree Sky Jump is a great EM! My first one was in horrible shape, looking like it had been stored outside without the glass ☹️ But, it was still fun! My 2nd one, which I scored a few weeks ago is about as minty as I could ask for! HUO since 1979 and very well taken care of! Definitely a keeper!

Update. Thanks for all the suggestions, I really appreciated it. When I had a closer look at the chime unit I noticed the lead to the longest (ie lowest pitch) chime was disconnected...voila! Problem solved.

It’s interesting that the three leads have connectors and not soldered. That gives me the option of switching the chimes around for 10, 100 and 1000 points. I guess I am a traditionalist since I chose low middle high respectively. I like my chimes... they ring loud and true!

I love my Sky Jump Machine, and consider it one of the funnest EMs I have played.

I have a slight problem that maybe someone can provide advice? Every once in awhile, knocking down the 7th drop target results in the scoring going well over 5000 points; Which set of switches should I be looking at to clean and/or adjust? Thanks for your replies!

Does this happen only when you have all seven numbers lit?

No, it happens when I hit the last drop. Sometimes, the scoring wheels keep going until I hit another scoring target. I trapped the ball the last time it occurred and ran the score up to 98,000 before flipping the ball......my wife was amazed when I showed her the new high score, but I fessed up.....lol

I think mine sometimes over scores on the last drop target too but I need to watch someone else play to be sure. I think what happens is that the last target scores the 5000 pts then the bank resets twice (sometimes) thereby scoring an extra 5000. I’m pretty sure that DIDNT happen on the game where I rolled it (that’s my story and I’m sticking with it )

Sorry, I am a bit of a noob so I can only commiserate with you at this point. My guess is I have a switch or relay that needs adjustment.

Is anyone looking to upgrade their Sky Jump? I have a beautifully restored example for plus a Wade Krauss repro play field ( this game doesn’t need it).

Maybe the machine, don’t need the Wade Krause playfield.

I could be interested in the playfield if Electrocute gets the game only

I posted this in the resto section but thought i might get some better direction from SK owners since it has to do with my Sky Jump directly..

Hey Guys,
Most of the tech work has been done on my new Sky Jump. Its playing real nice.. Its just about time to order my Molotow paint. Im torn on what color of white I should choose for the entire base of the cab and backbox. I am leaning towards Nature White (Tan) #5 but I am wondering if Signal White #231 might be a better choice? The base will also get a speckle ( fine splatter ) effect as well.. In addition I am leaning towards Signal Red #33 and Shock Blue #94 for the stencils.. So Im wondering if someone with experience using Molotow on a cab could give me some direction. Thanks..
here is the Link to the Molotow Color Chart.

Also if anyone has any good tips on caps and such that would help but right now im leaning towards ordering a bunch of fat caps.. including the Ghetto Blaster.. and i am also planning on laying down a primer.. im going to use Kilz original as recommended on this forum by the majority.
Thanks again.

Hey fellow Sky Jump owners and players. Does your Sky Jump have a higher rate of the ball bouncing back from the lower apron, and back to the playfield? More than other Gottliebs you play? Have you noticed this? Or could this just be my game?

was only thinking the same thing playing mine over the weekend.

The ball rolling down from the upper right pop bumper or upper right stand up targets, will roll down through the flippers, and bounce right back up, almost on to the right flipper. This does happen on other Gottliebs, just not as often. Any one else have any comments. I'm not to concerned on fixing the problem, but a thin layer of foam, attached to the apron might stop this from happing.

Happens to me quite frequently too. Just part of Sky Jump’s charm. Can’t beat the old Lazarus ball.

I’m interested in upgrading my Sky Jump. Did you already part with yours?

would anyone who has replaced their playfield know how many and of what type light sockets need to be purchased? Im am about to do a playfield swap and I am thinking I will need at least 20x 1 1/8 and 10x 1/2 sockets as well as a few lay down sockets for the top rollovers.. im not seeing any 3/4 brackets or at least I dont see any,. Could anyone confirm ? Thanks

Anyone have any pointers on a sky jump that is playing 4 or 5 balls instead of the 3 it is set at? I have completely taken apart and cleaned the ball count stepper unit (it was frozen solid when I got the machine).

The underside of my playfield is signed in pencil by “Ed K” and I assume that it designer Ed Krynski. Is this normal? Anyone else have this?

I've joined the Sky Jump club! And I can confirm mine has the signature just like yours as well.

Hmm, I'll have to check my playfield.

I joined the club a little while back. I really like this game and think it is a sleeper when it comes to wedge heads. The playfield layout and rule set are really what I consider to be some of Ed's finest work. I love the fact that the game rewards you for hitting all the 1-7 shots by multiplying the drop target points. I also love the 5000 bonus for completing all of the drops. So this game rewards for both accuracy and having a good old drop target romp. I consider this game to be every bit as good as Volley and better than C37; both of which I have owned for years before getting Sky Jump.

In a way I am almost relieved that my playfield does not have the Ed K signature on the bottom. The playfield is pretty trashed with a lot of wear to the wood and cupped inserts. I managed to get what is possibly the last Wade Krause playfield recently along with my new C37 field that was just released earlier this month.

Now he just needs to do Volley. Repro backglass would also be nice.

Curiosity got me! My Sky Jump doesn't have any signatures under the playfield. But that search, got me to play around 10 games, something that I have not done in a few months.

Anyone have extra used sling shot plastics?

Just an FYI for the behavior of the Multiplier Control Unit stepper...

When the 10x insert is lit at #7, every other cycle it will require 2 pop bumper advances to wrap around to light at #1.

This is because the stepper has 30 total positions/rivets that manage 4 cycles of 1-to-7 advancements. 4 cycles of 7 positions is 28 positions, leaving two “extra” positions/rivets on the stepper. Each extra rivet is wired to the preceding 7 rivet. Like so:

1234567 12345677 1234567 12345677...

I was questioning my stepper’s cleanliness/functioning until I took a closer at its design and wiring.

I wish I had a picture of the other side of the stepper wiring but all I have is this side:
A7E81429-E7C4-4BAF-B1BA-46543DD33BBE (resized).jpeg

Technically the rivets are referred to as “0 pos” to “6 pos” on the schematic, but I am using 1-7 above to refer to the insert numbering.

Thanks jeffc for that nice explanation. I was wondering about how that pattern came to be.

Ah thanks, good info. I briefly had mine on liberal and that behavior was confusing me at the time too. Makes sense now.

Joined the club about a week ago. Game is in decent shape cosmetically and plays fine. A little spiffing up and it can join my other EMs.

I played SJ a lot back in my college days and am glad to finally own one.

Welcome to the club! Out of my small collection, Sky Jump is my favorite to play.

I'm in. Here's my Sky Jump webpage...

About to join the club in the next few weeks.

It's only fitting a former skydiver gets a skydiving pin. I'm looking forward to the game play and skydiving induced flashbacks it should give me.
