I am going to be checking out the slot machine to see the issue.
What has happened is when any win occurs the TILT light goes on the timer shuts down the slot machine, I can reset the machine, everything works until I hit a win.
Any suggestions? Mind you it's in excellent condition, no wiring butchered, everything is correct, been working excellent for many years. I am thinking a switch is the problem, or a relay. :Scratch-Head:

Dave, check to see if anything is jammed in the hopper, blackout timer only comes into play when hopper is empty or pay is delayed.The wizard .

if no hopper jam, then keep reading.
the safety timer is the one that shuts down all power to the machine except the neon light on the motor bracket.
on many 1090's, there's a hopper cut-off (HCOR) relay. If it loses power, a switch on it will turn on a tilt light.
the HCOR has a 50MFD capacitor and 1N4004 (or 1N4007) diode connected to keep it powered in between recharges from a hopper pulse switch.
when the game is first turned on, the HCOR is not powered. When the handle release trips, the relay is powered. You can also power it using the reset button inside the door.
once powered, the HCOR stays powered via a switch on the relay and a switch on the unpowered payout relay. When a win is detected, the payout relay powers and now you need the hopper pulse switch to periodically close to keep the capacitor charged enough to hold the HCOR powered. If the cap discharges, the HCOR unpowers and you are back to game power-on condition.
when the HCOR is unpowered, the hopper cannot turn on.
your HCOR must be working or the tilt light would stay on. If the HCOR unpowers as soon as the payout relay powers, then the capacitor or/and diode failed. Usually it's the capacitor.
if you get a couple coins ejected before it shuts down, check the hopper pulse switch with the yellow (30) and brown/orange (67) wires on it.

Pulled the hopper, a loose screw caused a coin to jamb. That's easily peasy with some place to start. It is even more easy with a super clean slot machine, in great condition to work on. :thank_you:

The coin jammed, and great explanation of the hopper issue. I'll keep it in my notes. Question, the capacitor is from 1979 do you think it's still good to go??? When do they dry out and fail? :Scratch-Head:

there's no way to know. There's caps from the 1940's still working okay, and ones 10 years old that fail.
there are meters that measure the ESR (equiv. series resistance) of caps. As they start to deteriorate, the resistance goes up. That makes them run hotter, which reduces their lifespan.
in this case tho, you don't care if the cap is going out of spec. When it stops working, you replace it.
if you have a few machines and don't want downtime waiting for parts, it's good to have a spare handy. The 1n4004 or 1n4007 diodes you automatically get spares when you need one ... they are so cheap they are sold in bulk packs.

I have a lot of that stuff, radio capacitors, etc. I will take a look at what I have in the workshop. :applause:

I was still having jams in the hopper. I took the coins out, then put some back and ran it, everything is working, and I kept putting in handful of coins without a jam. The two bearings on the bottom of the hopper are working, could they possibly be dry if a load was placed on them.
So if the coins jam the hopper what was the issue, any ideas???? :Scratch-Head:
I have two slot machine that are keeping me busy, and now a Pachinko machine. :duh:
Seems like everyone said that I would stay busy with two slot machines and they were right.

Is there a chance that your machine was once a half dollar or silver dollar slot. A hint would be that the pays are rapid fire and not slow and orderly, that would help coins to stick and jam. Also a drop of oil on all3 bearings would not hurt anything.

Nope, it's all original 25ยข, slow and orderly. The bearings were bone dry.

Oil em up !
