Trying to work through my Air Aces, but am stuck at the first major hurdle. The game has credits but won't start. I cleaned and gapped all switches. Fuses and fuse holders are good, lights turn on, lock coil turns on, so it's not a power issue I don't think. Hit the start button and nothing happens. I tried jumpering the start button to the credit coil and nothing changed. Tried jumpering a couple other wires to the credit coil in the red line I made on the schematics in Pic 1 below but nothing happened. When I manually hit the reset relay, it attempts to reset everything but Player 1 and 2 score reels don't zero out, even though the coil that I think should deal with that (#1 Score Reset) is firing. Player 3 and 4 score reels do though. The credit unit does not decrement. The switch on the score motor which deals with the drop targets resetting (9a shown in pic 2) gets so hot it starts smoking after the score motor makes about 5 rotations. Any help appreciated.

Hi Rolf,
Thank you for telling me about the dangerous voltage, I didn't realize
Manually tripping the Coin relay does attempt to start a game, but it never gets past the reset phase because the first and second player score reels don't zero out properly. It never gets to the point where the ball is kicked into the shooter lane so I can't test if the Game-Over relay trips. For the sake of testing I could try setting them to zero manually, unless you think it would be better to address the score reel issue first.

Thanks,
Dylan

Player 1: 11100
Player 2: 11110
I also noticed Player 3 wasn't resetting properly either
Player 3: 00010
Player 4: 00000
Something I realized is that I never took apart the score reels and cleaned/lubed the bakelight discs for them. Could this be causing my issue?

Player 1 tens drum does this: at zero, the 3 switches in the stack are all open, at one through eight, the top 2 switches are closed while the bottom one remains open, and at nine the 3 switches in the stack are all closed.

Yes #1 and #2 Reset Relays are rhythmically activating

Attached is a video of what my Game Over Relay does from when the game is on, to pushing the coin relay in to start the reset sequence, to turning the game off then back on again.

Did that already, but just to make sure I went back and cleaned it again. Nothing changed

When manually setting the score reels to 0, the game does properly start and kick the ball out. Still having an issue with the start button doing nothing...
I played around with the score reels a bit today and made some progress. When setting every score reel to 1 and tripping the coin relay manually, my results are:
Player 1- 11100
Player 2- 11100
Player 3- 00000
Player 4- 00000

It's strange how both Player 1 and 2 are having identical problems. I don't see the wire-30-Yellow broken anywhere. I tried jumpering the Drum Zero wire of each score reel directly to the 30-Yellow wire (for example, for Player 1 100-900, the W-B wire), and it didn't make them reset.

Here's the updated video of the Game-Over-Relay and how it behaves when the machine actually starts a game. Let me know if it looks problematic, I'm having trouble following this part of your instructions

Welp I goofed up, I was messing with the game and now the score motor doesn't reset... add another problem to the list

Edit: im gonna have to get this fixed first. Now when manually tripping the coin relay, the reset relay sticks on and the game doesnt reset. The score motor, when manually moved out of home position, doesnt automatically reset anymore

Edit 2: No longer an issue, I fixed this by moving the jones plug for the 3rd coin chute? Weird....

I checked it and visually it looks good. I also did try continuity check between both ends and I did get a beep.

Something else I discovered is that the game starts (or tries to start) when I hit either of the micro switches in the coin chute, but not the start button. Strange....

I was able to get the game to start by jumpering these two together (I believe it was that white wire. I jumpered together the white wire that connects to the middle switch on the 2nd Coin Chute Relay, and the BLU-O wire on the Credit Button). There is no 3rd Coin Chute Relay in my game. I believe this indicates a problem with the 1D position on the score motor? I've cleaned and gapped the score motor already. I'm not sure if the "2nd Coin Chute" refers to the relay or the actual microswitch?

Then disregard, it was irrelevant. I tried what I highlighted in blue, then green. When I jumpered the start button to the credit relay and *pushed the button*, nothing happened. When I jumpered the R-W wire to the credit relay, it instantly started a game as soon as I turned the machine on. I'm guessing this is because the 2nd coin chute switch is normally closed?

*edited for clarity*

Right, but the side I jumpered it to is closed. Is this why it caused the credit relay to start instantly?

Heres what 1D (top switch) looks like in the home position (trough) of the score motor

Going back to the score reel issue: I tried jumpering the 10s reel to each of the other reels in the row to make sure all the coils work, and I didn't have a problem. Then I tried starting the reels at 2 instead of 1 (Player 1: 22220 and Player 2: 22220). The results were: (Player 1: 02200 and Player 2: 02200). When testing this I went to the back of the game to watch the coils to see if they were struggling at all, and the hundreds and thousands reels on both banks weren't moving at all. I'm not exactly sure what these results mean in terms of finding a solution though...

Edit: tried (Player 1: 33330 and Player 2: 33330), and the results were (Player 1: 03300 and Player 2: 00000). Im now extremely confused because there seems to be no consistency

Edit 2: it appears that player 2 thousands and tens is fixed, and I'm not sure how I did it:
Start ----> results
Player 1: 11110----------->01100
Player 2: 11110 ---------->00000
Player 1: 22220----------->02200
Player 2: 22220 ---------->00000

To try to fix Player 1 hundreds and thousands I'm going to take them apart and clean them. Cant think of anything else to do at this point

Solved the score reel issue, only for another one to pop up. Now every single reel resets except for Player 4 tens reel. I fixed the Player 1 hundreds and thousands reel by taking them apart and cleaning them (they were filthy), and cleaning the contacts again. As for the Player 4 tens reel, it started sticking. The coil tries to fire but it almost doesn't seem like it has enough power. Attached is a video of how it behaves when I try starting a game: https://drive.google.com/file/d/1CQImU-hHFF5_-wWus3hzH8nerDY_Pg6I/view?usp=sharing
Manually pulling in the reel works fine, and when I jumper the hundreds coil to it, it pulls in just fine, but when trying to reset on its own it gets stuck.

I will try this, thanks.

I went back and looked at the schematics, my game and your comment, and I'm better understanding this. The NC switch on the lock relay opens when the lock relay engages. As for this part:

When toggling the game off, resetting the Ball-Count-Unit by hand does nothing because it's already in the home position. From there, what I showed in the second video is what happens to the Game-Over-Relay coils.

As for the switch with the Yellow-Black wire (the very top one), attached is 2 photos of its two different positions based off of the position of the latch. Looks correct to me
