Coin Optics and Hopper Optic All Read Zero
« on: April 20, 2018, 06:07:24 PM »
So I know I had another post, but figured this is an entirely different issue and worthy of a new post.  So I got all the components installed on my game...got the comparator up and running...(i think) but all my coin optics still read 0 and the coin out reads 0.  I have an extra coin optic that also wont work...the chance that both of them are not working I find kind of hard to believe.  I've enclosed some photos of my inside of my machine...something tells me that something is missing or somehow the optics were turned off...not really sure but im ready to pull my hair out over this lol

Can you pull out your mpu board and post a good photo of it, showing the entire board? Also, have you examined the motherboard (the smaller board mounted on the bottom floor of the machine? Look for any water damage, loose connections on the connectors that plug into the motherboard. Do all of your player pushbuttons light, indicating the power supply for that circuit is working? Are there any fuses in the machine, if so check that the fuse cap fits snugly onto the top of the fuse.

It is always good to thoroughly inspect a machine that is new to you. No telling what might be present until you look.

All lights work, fuses all look good and have continuity on each one when using my meter. Pics to follow in a second. Just need to upload them

With the door closed does the machine look like it is ready to accept a coin? If you insert a coin does it get rejected back to front coin tray, or does it go to hopper?

Gets rejected. Only way I can get it to go into the hopper is in test mode and turning the jackpot key on the coin lockout setting...my display says call attendant, coin in timeout

Are all of your dipswitches on the mpu board in the OFF position?

According to the self test, on this board all of them are unused except the first one which is 60hz or 50hz. This machine is on 50hz

I think you need to change that to 60hz, you are in USA right? The wall outlet has 120volts AC at 60hz electrical power.

ok, all is good on your line freq selection.

I don't know about those wires that are not connected. The red & black pair look like heavier wire, and those colors are typically used for some kind of power connection. Can you tell where the unconnected red & black wires go to on their other end?

They don’t appear to go anywhere. I just swapped out the coin hopper optic as well and still nothing.  This is def frustrating

Check the white connectors (called Molex connectors) that plug into the two motherboard connectors I've circled in your photo below. Look at the mating connector (connector with wires attached) to see if there are any darkened or brown discoloration on the white connector housings. This would indicate a poor connection on a power supply pin that is getting overheated.

Sometimes we have people that can only login overnight for a few hours, so some problem discussion threads need patience for all possible ideas to get suggested.
If things like this were easy then women would take over the world, that's why they need us.  :garfield:

I don't know what those loose wires are for but I'd wrap their ends individually in black electricians tape for now, just to keep them from touching the bare metal chassis ground. That's the safe thing to do. All 3 of those loose wires look like they have a connector contact crimped to it, like it was removed from a connector. It's not unusual to find unused wires in a machine, sometimes they are there for optional casino equipment, like a progressive jackpot or security equip or player's card tracking equip. But these don't look like that to me.

Do the red and black pair of wires reach to the hopper connector area?

The molex connectors look good. No burn or anything.

Could a dead battery be causing any of these issues?  The battery read at 3.6 when I tested it

I don't think a dead battery would give a coin timeout error. But if your battery is 3.6volts that is what it is supposed to be.
You could put it back together, see if anything has changed, if so then suspect a flaky connection. If still the same then take a break from troubleshooting, give a chance for other more experienced people than me to read thru what has been posted. They will digest it, maybe form an idea and post something.

When you went into the self test screen for inputs did you try putting a popsicle stick, tongue depressor or narrow strip of cardboard about the width of a nickel down between the coin optic boards? That should cause the ABC inputs to change from 0 to 1.

Also, since you had door optics problems before are you pretty sure they are working ok, when you close the door the machine senses it is closed? I think you will get a message on the screen that says "closure" when the door is shut.

Door optic is working. Replaced it tonight and tells me door open or nothing if it’s closed. Here is a closer view of that spot on the board
