Would this be the place to ask about a older 25 cent Williams slot machine, Model 13 mw-13 is on side of machine. I just picked this up with some older EM machines, i dont know much about these, it lights up and takes coin with a ding, but the arm ratches sound as pulled down? as you pull down but the reels dont spin? does the hopper need to be filled to have this check to work? thanks for any info and help

Do you have a reset button on the Power supply?
Open the door Let us Look at the Power supply
and Door Parts. and Computer Board.

Once you get an software or hardware error, Need to clear it, First.
with the Key switch on side of Cabinet or Reset on Power supply.
Even more important when the reels are Not turning.
And you want to make sure The OAB is engaging on the
Switch , You Can use the service Mode to test all switches

I will post the pictures but i think this machine is older, i dont see a computer board? I dont see a service mode test and what is OAB? thanks
 
One Arm Bandit . Lol
Board it's hidden so no one can find it
and you look at reset on power supply
And side reset key on Machine?
Anyway pictures tell the story.
 
here are some more inside pictures to see if any help can be given to get these to spin etc.?

Fuses still good?
What are the switches label as?
may have stuck relays on relay board
Need to jump the door interlocks
So you can coin Up and see if you get to where
You were after you pull the arm
see the solenoid on the right side
As you close the solenoid for the OAB
And reel should turn.
then mechanical part is working.
And if you have voltage on the solenoid
May need to confirm some things
If no schematic to look at.
also if fuses good
I just notice the reset key
Close door turn key on right of machine
And see if reels reset
