Most likely the score reel contacts are dirty. When the reels get to zero a contact closes to tell the machine its ready for play and it pulls in the db reset complete relay on the control bank. Most likely those contacts (1 set on each reel) are dirty, needs a cleaning. I can get you a pic if needed.

what pinhead52 said.

I'd manually actuate each non-zero score reel's plunger by hand to advance them back to 0. Then try starting a game.

Also, I'd start reading this:

Also, here is the startup sequence for Sky Jump:

Anybody who calls them "flappers" is gonna be in way over his head on this one. You really need to find someone local who is into electromechanical games.

Fortunately it's a one-player so pretty simple but a total newbie is in really bad shape when it comes to EM games.

It could be any number of different issues - switches, relays, switches in the score motor, or the scoring reels.

from Pinrepair.com:
Before Beginning: Introduction to Pinball Repair
Before attempting any pinball repair, there are some basic questions that should be asked. Simple things like, "how is the playfield glass removed?" or "how is the backglass removed?" (if you're asking these questions, even this basic document is probably beyond your skill set, and I recommend hiring a professional to fix your games).
But a very simple thing that is often asked is, "what equipment is needed to fix a pinball?" This document covers the electronic equipment needed, and how to use it. And the other repair guides cover the basic non-electronic tools needed for each system of games. But for completeness (since we mention all the electronic equipment needed below), here are some basic non-electronic tools need for pinball repair.

Screwdrivers: two phillips (#1 and #2), two flat head (one small, one medium).
Nut drivers: full SAE set (english units).
Wrenches: full SAE set.
Allen wrenches: full SAE set.
A good shop light.
Flexstone (EM games only) for cleaning switch contacts.
Contact adjust tool (EM games only) for adjusting switch contacts.
Beyond the basic tools, a level of "common sense" is also needed when fixing games. Remember the people that designed these games were probably much smarter than you and I, so we need to trust their design (unless I tell you otherwise, ha!) If they have a connector on a board, and it is burnt, it's best to replace it (and not solder wires directly to the board, circumventing the connector, and making the game "unservicable" in the future!)

As my buddy Kirb says, "Now let's start with some basics. Do you know what an amp or volt is? Do you know that electricity can kill you? Are you scared to look under the playfield of your game when it is turned on? Think about all of this before trying to save $100 and fixing a game yourself. For those of us dumb enough (like me) to waste time working games, we should all first learn how to do so." Hopefully this document (and some common sense) should save a new pinball learner some trouble.

I think I've seen this game around here somewhere before...

Exactly! Thought the same thing this morning. From the previous days, Topic: "Help diagnose a friends Wedge head."
Least now we can now go direct to the owner.

Just like I told your buddy that F relay probably has Zero to with your issue.

It's spinning isn't a cause, it's just a symptom, like the constantly turning score motor.

Focus on the ball count unit. Focus on the score reels. If there is a reset bank or latch trips in the bottom of the cabinet, I'd look there too.

Ha yeah I was going to send you a link tonight, SkyJump74, but you beat me to it. Now you know the secret source of all my pin knowledge! These folks are definitely the ones to ask. Sharp eyed people have already spotted this thread https://pinside.com/pinball/forum/topic/help-diagnose-a-friends-wedgehead#post-3075700 was the one I started to put some feelers out for you. But I think at this point you already know more about EM machines than I do! (My sole and current pin project so far is doing a full art/sound overhaul of a 1979 Willliams Flash solid state pinball using the videogame series Mega Man as a theme).

Hi
I do not own a modern Gottlieb SINGLE player game. I looked up in the schema of my Far Out, to distract / confuse people who try to figure out "what will the "Number Match be in the next game"
(trying to count how many times I made 10 points -> conclude / deduce "next No-Match": My Far Out does step the F-Ministepper forward when the pin steps forward (towards Zero-Position) the Score-Reels of Player-1. And when all the Score-Reels are stepped to Position-Zero the pulsing for "stepping forward" stops - for the score-Reels AND the F-Ministepper.

I say the same as "CrazyLevi": The stepping (endlessly) of F-Ministepper is a SYMPTOM - the pin does not realize (does not get the information) Score-Reels ARE at Zero-Position.
So -> Post-4 -> the Startup-procedure -> "A-Relay-Reset-Coil should fire". Maybe a wire to that coil has broken-off (coil cannot fire) ?
Want to try: At the time You would like the pin to stop stepping -> manually actuate the A-Relay-Reset-Coil ?
Want to try: Take out ALL Score-Reels and have a close look at ALL reels / ALL Zero-Position-Switches -> do ALL Reels / Switches act 100% identical ? Greetings Rolf

There are two people in Kokomo with EM pins. Maybe send them a message and they can help locally?

Like Stashyboy suggested, read thru the pinrepair site and also what helped me a lot when I started was the "This old Pinball" or TOPS dvd's. Especially the EM ones. I believe they are listed on the pinrepair site also.

F-I-E-L-D.

I don't know why "feild" drives me crazy, but it does. I before E, except after C...

If the match relay continues to spin I would just say it's a stuck switch on the playfield somewhere, especially if it was working before. Why is this fact being ignored? Am I wrong?

Also sounds like your ball count unit is gummed up which could also cause this if it doesn't detect it reset. I file down the contacts with high-number grit sandpaper and wipe off, adjust the springs, and you're supposed to add Teflon Lube Gel on the contacts too, but I don't do this. (and probably should)

I'm a big believer of "don't fix what isn't broken" especially given your lack of EM repair knowledge so much better to diagnose first than go through and rebuild the whole game. It was working fine(?) before this happened, so it's obviously not too bad.

You mean the credit counter? the wheel in the head that goes from 0 to 15 (8 if the post is in an alternate place). Yes these are usually gummed up and need to be cleaned/worked so all the leavers move freely

Its the credit counter.... if you coin up it adds credits, if you win games due to points or specials, it adds. Start a game and it subtracts... If at zero, game wont start unless contacts are hacked...

I can show you how to jumper the credit wheel (aligator jumper) to have the game set for free play. ie 2 sets of contacts open when the post on the wheel comes around to zero, the set of contacts that have the pvc coated wiring you jumper (keep closed even at zero) will allow the game to start with the credit button

Here's my Sky Jump, needs a little work (this is the third one Ive owned)

Hey

If you are coming to pinfest I can give you a far better cabinet for that sky jump!
You need it.......

Its in your back yard, Allentown PA, May 6th and 7th.... the all weekend long flea market makes it worth the trip, a chance to stand around and berate the folks that think they can get top dollar for a pile of crap!

Is so much fun Im driving from Texas (empty) just to fill up and drag it home.
