So got it into my arcade. Turn it on and it is in a constant state of coining up. I look inside the machine and the coin counter keeps increasing. What do I do?

The coin mechs themselves are gone. There is 2 switches underneath where the mechs would be but manipulating them has no effect on the constant coining up...

I can play a game and the game scores correctly but machine keeps coining up...it jumps up to a 4 player game...any ideas?

I'll check it out. Thanks!

Cleaned and adjusted start button switch and coin door switches-no change.
Cleaned coin relay switches-no change.
Pulled and reseated every Jones plug in machine-no change.
Unplugged coin door Jones plug-no change.

Coin relay constantly fires.
Coin stepper constantly fires.
Machine constantly coining up.
Motor constantly runs.

What should I do next? Don't have schematics and couldn't read them if I did...lol.

Also unplugged the playfield-no change.

Help!

Thanks! I'll report back tonight.

Oh and the answer to your 3 questions are No, Yes, Yes.

Every relay in the bottom of the machine looks to be spaced correctly to me. Replay relay fires upon start up resetting players to 1. Then it stops firing and player counter goes up to 4 and continuously adds credits.

I looked at the schematics. I can't make sense of them. Every relays switches look to be spaced correctly and open/close correctly when actuated. Steppers all reset correctly when I turn machine on. I am lost. Think I got in over my head for my 2nd EM...not giving up though.

Could it be a switch on the motor? I hope not as that looks scary.

when I unplug the coin door the coin relay fires constantly still...does that switch you mentioned on the score motor control the coin relay? I will check it out. Thanks!

Coin relay fires immediately upon power up of the machine. Nothing I have done so far stops it. Not left flipper button not coin switches.

Progress! The top switch on the index cam was not opening. Gonna put playfield back in and see what happens.

Well I can add credits at coin door. Start button does nothing. Ball won't eject. I can drop ball in shooter lane and play everything on playfield seems to be in order. Game doesn't recognize ball draining.

Outhole relay does fire when manually activated. When activated ball in play never changes but player moves to 4 and stays there.

To clarify. Stays on player 1 and ball 1. But says 4 can play.

Game won't reset because start button doesn't do anything. I can get to reset by manually activating reset relay.

How can I get a game to start without pressing the start button? Or better yet...how do I get the game to start by pressing the start button? Start button does nothing. Won't reset the game (I can reset by activating the reset relay) and won't start a game. I can "play" but scoring and flippers are the only things working as a game hasn't actually started (game won't reset, ball won't fire into shooter lane, stays on player 1 and ball 1). Thanks so much for all your help so far! I really really appreciate it! Sorry for all the posts I just post things as they come to mind...

I cannot locate a start relay...is the reset relay the same thing? I found that if I hold down the switch in ball trough that activates the outhole relay while I activate the reset relay the outhole relay will fire. This is as close as I have come to replicating a normal startup sequence. However even after doing this when I lower the playfield and play a ball when it drains the end of ball bonus doesn't count down, the ball in play does not change, the player does not change, the outhole relay will not fire the ball back into the shooter lane.

I also made it free play...was hoping somehow that would help. Nope.

Everything needs to be reset before a game can start right? I just realized when I trigger the reset relay it always defaults to 2 players. Instead of 0 or 1. Could that keep start button from working and keep game from playing? If so I will remove and clean that stepper...rather have conformation that this may be the issue first though. Thanks!

Credit unit 0 position is closed.
Ball count is at 1 after reset relay is triggered.

Player unit starts at 1 after reset relay is triggered...so I will check that. Number of players starts at 2...So I reset the stepper for coin unit manually and it drops down to 1 player.

The coin unit stepper should be at max? Still not working.

Reset relay seems to work correctly when I trigger it.

Do I just make sure game over relay triggers "game over"? Don't see a game over relay although there is one that is not labeled. Turns out this is the game over relay. Seems to be working correctly.

What should I be looking at in regards to the bottom switch on the index cam? What does that switch do?

The credits did count down by one when the score motor ran continuously...I will add credits and try the start button again...if that doesn't work I will trigger the reset relay and see if it counts down by one. So start button still does nothing. Triggering reset relay drops credit wheel by two the first time then by one. Just like it starts at 2 players then increases to 3 and 4.

Damn file uploader won't work. Bottom switch on index cam is open when motor is at rest is this correct? It didn't make any difference anyway...

So I found the manual attached to the bottom of the machine. It shows whether switches are normally open or closed in all the relays. Made a few minor adjustments but everything looks good I think. Really didn't make any progress...one thing I noticed. When I add a credit at coin door (and machine jumps to a 2 player game like always) the ball would kick out into shooter lane. So I play and when the ball drains nothing. No bonus countdown, ball never shoots over to plunger, ball stays on ball 1, stays on player 1...And my start button still does nothing. Another thing that is weird is that if I hold down the advance bonus switch on the playfield after the ball has drained it will shoot over to plunger again...but everything else stays the same as mentioned above. I know this is going to take some time but man I just spent 4+ hours tonight on this and got nowhere...frustrating.

The player reset relay stays on once activated manually. Not sure if that would be the case under normal circumstances. Switches seem to be adjusted correctly.

I think the ball index relay stays on too when manually activated. Again switches look good.

Thanks! I'll report back.

Yes it was adjusted correctly. I sold the pin last Thursday for extra Disney World money. Definitely had more fun with that money here in 'Lando. Thanks so much to everyone for trying to help me out.
