overpaying

[aheg]

I have a universal slot machine and it has always payed out wrong i am finally attempting to repair it i dont know much about slot machines so can some one please help me out.
What i have tried
1.pulling out the hopper and lubing all the arms
2.tried cleaning of that sensor(not to sure what its called)
im not sure what else to try so any help would be appreciated
oh ps its a standard hopper

How is it paying out wrong? OVERPAYING/UNDERPAYING, both?

What game do you have?

What board do you have? 8116 or 8800

Its over paying im not sure how to tell which board i have and the machine is out of the ramada inn from state line

 Next post tell me the theme, name of the game, that will help. And tell me if it was ok, now malfunctioning, or always malfunctioning since you got it.


The 8116 board requires a sub-board at location 1A on the board. This sub-board has eight switches on it and one of those switches sets the hopper type, standard or high speed.
If this sub board is missing or is set wrong you can get error 31 for overpays. So if your machine has been doing this since you aquired it you need to check this sub-board.

Now, if it just started overpaying then you need to check the hopper kicker knife, solenoid, and spring. When the machine pays out it counts each coin and when it reaches the limit the disk stops and the EDITEDsolenoid drives the kicker up knocking the next coin out of the disk to prevent it from being dispensed causing error 31, overpay. If the solenoid is sticky or not working, or the spring is broken, it will fail.
In the pic below I circled the spring, the solenoid is on the left, black.

Opps, got that backwards. The solenoid activates when coins are dispensing and moves the kicker out of the way. When the limit is reached the solenoid deactivates and the spring returns the kicker to knock out the remaining coin(s).

Im not sure of the theme but the machine its just has bars and 7s
The arm on the hopper will retract but will not go out unless i manually push it the machine has always had this problem can you please post a picture where i could find the board sorry for these basic questions

Sounds like a hopper problem at this point. Not sure I understand the above??
Look at the picture of the disk area of the hopper. I circled in red the kicker sticking out. Push it in and it should spring back. If it does not spring back than check the spring pictured in the previous post. If the spring is there then add a drop or two of household oil to the solenoid shaft and excercise it a couple of times to loosen it up.

I lubed it up but i guess not enough because it does not spring back but it does have a spring on the back

[aheg]

actuallly im going to replace the spring i think that is more likely the problem

[uniman]

Yeah, it should snap back. I have found the solenoids gummy too not letting the spring do it's job. With the spring off the solenoid shaft should slide easy.
