So, when you press the start button, the score reels reset to zero, but the score motor keeps running? Does the ball kick to the shooter lane? Did you check the coin switches - are they open?...

Do you have the schematic for the machine? One of the switches that sends power to the score motor is closed and that's why the score motor keeps running. Just find the score motor icon on the schematic and work back on the circuit to see what switches control power to the score motor... Some simple things to check: Make sure all the score reel switches are adjusted properly and make sure the ball count stepper has reset to the zero position...

LOL

Everything looks good to me!

Issue could be any number of things. Sounds like your game isn't completing it's reset, and if it is, it isn't kicking the ball out. You have to start narrowing it down a bit. Are all game features resetting to how they should be when game starts?

You'll need to look at the schematic and find the score motor icon... Look to the right of the score motor icon to see what switches in the score motor circuit send power to the score motor. Or just post a section of the schematic here with the score motor circuit and we can tell you what switches and relays to look at...

I rather like Dirtflippers start routine as a basis of diagnosing start issues:

"Maybe the thing to do is to begin at the beginning:
- manually reset all score reels to zero
- manually reset all relay banks
- unlatch any interlock relays
- have a credit on the credit unit
- place the ball in the outhole
- press the start button
What happens?"

Check the switch stacks on each of the score units (score reels). There is a runout switch that must close on each score unit - that is what signals that the score is reset, and the game can start. Clean and gap the runout switch on each score unit to see if that clears up the problem.

If that doesn't fix it, look to see if any of the solder joints have failed where the wiring is soldered to each of the runout switch blades on the score units.

If that doesn't fix it, run a jumper wire from the 25 volt fuse to the non-black-wire solder lug of the AX relay coil that is not firing to confirm that the relay coil itself is good. If the coil doesn't fire, replace it.

If the coil is good and it's still not working, check the score motor switch stack at 1C to confirm all the switches on that stack are clean and gapped correctly, and that all the solder joints for those switch blades are still intact.

Good luck! - TimMe

Hi sgc1
I do not have that pin - I do not have a schema - I do not have a manual. You do have a schema - do You have a manual ? Closest to Your pin I have found is "Big Hit, June-77": https://pinside.com/pinball/forum/topic/gottlieb-golden-arrow -> AX-Reset pulls-in when all Score-Reels are resetted - through (turning) Score-Motor-Switch-2B. Want to show a snippet of schema showing the "actuating of AX-RESET-Coil" ? Greetings Rolf

When you use a jumper, it doesn't matter what switches control a coil. The reason you run a jumper wire directly from the 25 volt fuse to the coil lug is specifically to bypass ALL of the switches. When you jumper a coil this way, it will ALWAYS energize. If it doesn't energize, either:
- the power is off
- the coil is bad
- you didn't do the jumpering correctly
- the black coil return wire is disconnected somewhere (extremely rare)

Since neither AX coil fired when you jumpered it, it's possible you didn't do the jumpering correctly. Try this: jumper some another coil that you know is good (like a bumper that is working normally) to confirm that you are jumpering correctly. If you are, the known good coil will energize.

Once you are sure you are doing the jumpering correctly, try jumpering the AX coils again to see if they energize.

To answer your question about the switches: the 10, 100, 1,000, and 10,000 score unit runout switches as well as a switch at motor position 2B, all wired in series, are what trigger the AX coil to energize to take the game out of reset. On your schematic, this is the coil just below and slightly left of the motor symbol that is marked "AX" RESET. Follow the wire coming off this coil to the right and you will see each of these switches, one after another, on the wire.

Steve, sorry I'm not sure what you mean by hold relay.

Have you tried replacing the AX RESET coil? That coil should absolutely energize when you jumper it directly to the power supply. If the AX RESET coil isn't energizing when you jumper it directly, but the other coil (the trip coil) on the AX relay assembly IS working OK, then it really sounds to me like the AX RESET coil is bad.

Until you see for yourself that the AX RESET coil can actually energize when you hook it directly up to the power supply, I don't think you will have much luck trying to troubleshoot other parts of the circuit.

Another, simpler, approach to testing a coil is to jumper a fresh 9 volt battery directly to both lugs of the coil. 9v isn't enough to run it normally but is adequate to provide proof of life.

At least you have eliminated the coil as the issue. Now to find the offending switch(s).

Speaking of Dirt,

Where has he been?

His knowledge is incredible.

That's the coin lockout coil.

When the game is powered up coins are passed into the coin box.

When the game is turned off the coins are diverted back to the coin return.

For home use (assuming you aren't going to use coins) you can disconnect the coil to prevent it buzzing buzz. Just make sure the spring fingers that are attached to the coin lockout bar are not touching the coin switches.

No it wouldn't.
