Hopper stops after 1 coin out.

[capt7310]

I have an 873 that will eject only 1 coin no matter where the reels stop. I can see the spin cam for the coin mech when it ejects 1 coin, and instead of it advancing as soon as the plunger ejects the coin it moves back to the same spot on the board. I can manually move the spin cam and when the contacts get to a certain point on the board it will eject anywhere from 4-20 coins.  . I attached some pics maybe I'm missing something or a contact is off. The 2nd pic shows where the spin cam stops and keeps ejecting 1 coin,, but will not move from there.

first you want to reset the cam to zero position pull the hopper unit out and push the bottom plunger in this should set the hopper back to zero those fingers should be at 6 "o" clock position when reset to zero
next check that second finger is making good contact not saying it isn't but looks a bit bent to me
then set up a pay and see what happens

Hi do you mean the relay plunger in the bottom of the coin hopper

[Amechanic]

Yes on the bottom.. It's the plunger just behind the payout board..

That spring pictured in IMG. 2380 does not look correct to me . If it's too strong or tight then your hopper may not works correct.. Have you tried to advance the spiral cam by hand? Push the advance plunge 5-10 times, then push your lower one to see if the spiral cam returns back to the start position with your wiper fingers pointing down to the 6 O'Clock position...

[capt7310]

Yes if I advance the spiral cam by hand it will eject anywhere from 4-20 coins. If I push down on the upper plunger just behind the coin eject I can see the spiral cam advancing and if I keep doing that it will eject 20 coins, but on it's own it stops at say the 2 o'clock position and hangs there and will not advance. I straightened that 2nd finger and it makes contact. If I set the cam too the 6 o'clock position it will advance to it comes to that 2 o'clock position as in photo img 2384, then nothing no more movement.

[mark the spark]

capt if you look at the bottom of the payout board there are some numbers which correspond to the payouts
the spiral cam should always start in the 6 o clock position if you set or have minimum win say two coins the spiral cam should advance only as far as it has stepped off of the number 2 it then should stop on the next pull of the handle the spiral cam should reset to the 6 o clock position I cant make out wether your hopper is running away on payout or not ,so could you try setting a 2 win and say a ten win and post back whats happening

[Amechanic]

Mark,  Looking at the first pic this is a JPO (jack pot only) machine. Looks like 20 coin is the smallest payout, then 100, & 200 coins.

Capt, if you manually advance the spiral cam, does it stop in the same location, or will it advance past there?

[capt7310]

OK Guys Hang on he I go...... Did everything, setting the spiral cam and yes if I manually moved it, it would kick out 20 coins. So a little adjust here and there, WHEN all of a sudden the top part of the machine starts this loud humming and the reels start chattering and the F-ing machine starts spitting out coins that I almost had to take cover cause they wouldn't stop flying out of the hopper... and then the top of the machine SMOKE starts coming out, this looked like something you'd see in a cartoon. So of course I immediately shut it down opened the top and the plunger relay fried. So what do I do... yep let's touch it. So now I no longer have a fingerprint on my left index and thumb. So now this has become personal and I will fix this F-ing machine. So guys I need a relay and the part # from what I can see from the burn unit is B-25-925a/975a. Don't know if anyone has one but if you do let me know.

Hey Paul,

Can't take these things personal and no cussing around your machine.
It might blow a coil. Just kidding!
Send me your address via a personal message and I'll send you a coil.
Thanks to Jon (Ovenguy) who loaded up my truck with parts a couple of years ago.
You might want to have your top glass out and someone to pull the plug when you get the machine ready to test.

[capt7310]

Thanks Dave I'll PM you

Yep, that's a B25-925A, probably the most replaced solenoid on the Bally. I know the # from memory.
Several reasons they burn up, but one major one.  When that coil (odds step up solenoid) fully steps, it is supposed to open your EOS, or End of Stroke switch which is mounted just above the solenoid, attached to its linkage. (an N.O. switch sticking straight up and opened by linkage.)
If it does not open when the coil plunger is pulled it, it will keep the coil on, and after about 5 mins it starts to melt. That switch is there to kill power to the solenoid AFTER it reaches its max stroke.  Somewhere there's circuitry for it and I'll have to dig out a schematic. Also, imagine if the EOS was not in circuit, and a coin was stuck holding down on your coin in switch...it would burn up.  I think that's why Bally put it in circuit.
Gets real freakin HOT as you found out.  You should see people run screaming when a bally on a casino floor starts pouring out smoke.... Pretty awesome.
I'm pretty certain it was NOT caused by your pay problems, but was incidental.

[DavidLee]

Paul, when the reels align for a payout the hopper will start to run. Then continue to run until the odds unit step up wipers runs off there respective metal receivers. Somehow this circuit is being interrupted and the motor shuts off.

[OldReno]

Try tugging on your carriage (the silver horseshoe shaped thing that holds your spiral cam in place). If it pays then you should remove the spiral cam clean its fingers and also clean your pay board. The innermost wiper finger is the 'feed' and if dirty can cause this type of problem.

[OldReno]

Also check where the spiral cam fingers reset to. They must be touching the beginning of the pay tabs, not off of them

[capt7310]

So that I'm sure what you're telling me I should check. In photo IMG 2384 check that piece correct. I did straighten out that one contact. I have the new relay and will install it and hope things work. TY

[Amechanic]

These contacts on the spiral cam are what OldReno is referring to. They need to be in the down posision or 6 O'Clock at the start of your payout cycle. The other part your referring to is a coil, not a relay..

Well this has turn into a total cluster, I installed the new COIL and now the arm no longer locks after the coin drop. The arm you can pull down without dropping coins. When I remove the upper panel and reinstall it and place a coin through the coin slot,  it will drop 20 coins, then the arm no longer locks in you can just keep pulling it down without the coins

[capt7310]

The headache keeps on going ... I put the new coil in and now when I pull the arm it no longer locks in meaning I don't have to add coins the arm keeps pulling down without inserting a coin.  The insert coin light doesn't go on and I found a cracked resistor I'm not sure if that's a factor to this cluster. Any thoughts other than "FOR SALE".

[capt7310]

Don't know what happened to the reply message. But the new coil was put in and now when I pull the arm I don't have to add coins the arm doesn't lock back anymore you can keep pulling down on the arm without coins and the reels spins and stop as they should but don't have to add coins. The 1-5 coin light stays on as where before as you added 1-5 coins the light would indicate such,  the coin insert light does not go on either. The upper control unit seems to be a total cluster now I also found a cracked resistor don't know if that's an issue.

[DavidLee]

The odds unit appears not to be resetting. When the odds unit resets back to 1st coin the handle release coil is energized thus dropping the Latch Arm in front of the Lock Pawl. This enables the handle to be pulled. Will have to figure out why the coil isn't resetting the odds unit.
