So I just purchased a Bally Skyrocket. Thanks @nicvolta you successfully got me hooked. If you haven't seen the video that he made of the one at Roanoke Pinball Museum, check it out here: https://www.facebook.com/roanokepinballmuseum/videos/786291921898163/

Anyway, I picked up this Skyrocket in Wichita KS and I need a little help getting it to play correctly.

First of all, it is set on free play. When I start a game the relays start tapping over and over but the 10's wheel on player one wont reset. The other score reels all go back to 0 accordingly.

I have found that if I manually actuate the 10's solenoid and move the 10s reel back to zero then a game will start. During the game almost everything works as it should. But when the ball drains, it does not move to ball 2, it immediately kicks the ball out again.

I am pretty good with a multimeter and I have a copy of the schematics on hand. If anyone has any suggestions, im all ears.

Thanks for the help!
Steven

Thanks that seemed to help some. Now that the 10's reel is resetting properly I can start a game. But when the ball drains it never moves to the next ball in play. Stays on ball 1 as indicated on the backglass

It seems to me that the ball index is not pulling. If I manually push it it will advance to the next ball. The ball index coil doesnt look burned, but its not pulling when it needs to.

Making progress. You were right. I cleaned EVERY contact on the score motor unit and was wiggling the wire harness when I head a click noise. Now it is properly moving balls and ending game as it should.

Now I've noticed a new problem. When I press the credit button once. 2 players are automatically started.

Also, the thousands reel for player 2 is not turning. I did take all of player 2s score wheels out and cleaned them.

Perfect! It was a little sticky. I cleaned it and now I can play one and two players respectively by pressing the credit switch once and twice..

Player 2 thousand wheel I think is the only thing left not working.

Cleaning the player relay fixed the problem with the 1000s reel not turning on player two. I actually played a full game!

Alas, I turned the game off for a while and now when I turn it on, the score reset relay clicks over and over and the score motor continues to spin, but the score reels are not resetting.

Bummer. One step forward, two steps back. Lol

Also worth mentioning... the 10 point relay is hot to the touch. Ill check to see if there are any stuck switches possibly making this happen.

Found the problem! My match stepper unit is partially missing. Until I get new parts for it, i cut the wires off the coil going to it. I think its okay to do this as long as I keep the two wires tied together.

As of today. The game is playing as it should. May just need some minor adjustments here and there.

ArgosySK I found another little quirk I would like to correct.

When I open the top gate, and then hit the switch to open the bottom gate... the bottom gate opens respectively. But when the ball goes out the bottom gate and in the shooter(or the drain), the bottom gate does not close like it should.

The shooter lane switch is clearly opening with the ball in the lane. What would cause this?

Looks like the open bottom gate relay has been this way a long time. It is not relaxing when it needs to. But when I kill power to the game it lets up instantly.

I was able to manually do the process above and the gate closes as it should.

When I hit the open bottom gate switch, the gate does open, but I am not scoring 3000 pts.

I'm assuming you're talking about these? I used a flexstone file on all three. But no change.

Bingo!!! This is the 3000 relay.

Can't I just unwind a couple winds and scrape off the wire coating and resolder the wire to the lug on this coil?

I actually couldn't get any windings off because that winding went straight to the center of the coil. If it were the other side i could have saved it. In the meantime, I swapped it out for the 2nd coin chute coil relay as it was the same coil number.

Update to the original problem though, the gate now opens and closes every time, but oddly enough, im not getting the 3000 pts when I open the gate.

Sorry, meant to report back and got carried away with other things. I am awarded 3000 pts when the Skyrocket is on 3000 and I collect it. But the target behind the upper gate does not give me 3000 pts. The relay does pull in and release but the score reels dont spin.

I was a bit confused by your instruction for the motor switches. Are they labeled and I havent noticed?

Meant to reply. Started a Skyrocket club and got distracted. I think the problem has resolved itself just simply by playing a lot. 3000 points are being awarded now.

Eventually I'd like to get the match working. But I believe that I need to order a coil and probably other parts to get the mechanism operating. Can you post a picture similar to my first picture here so I can verify what all is missing from my mech?
