Help with E1090-1

[rjpohl]

Thanks Dan,  I'll try the 2nd board tomorrow.

[rjpohl]

I found that I had the ribbon cable between the MPU and I/O on wrong.

power on:
tilt, insert coin and coin accepted lights are flashing
bell is ringing
hopper is jerking a small amount every second or two (moving but really slot)

I've tried 2 different hopper boards (1 is the replacement type I purchased from  Foxslots.

I bench tested the hopper (connected 110V directly to hopper motor) and it runs fine.

I feel like I'm getting close to repairing this one, at least I hope so.

[dhellis]

Is this jerking apparent with both MPU boards? if so then try swapping I/O boards. If the jerking continues then
you may wish to check the switches on the hopper as well as the hopper brake

[rjpohl]

I believe that the slot is trying to complete a payout.  If I could find a way to complete/clear the payout it would help determine if the problem was confined to the hopper/board.
I will try swapping out i/o boards tomorrow.

is there a way to complete payout???? 

thanks
Bob

You can flip the coin switch repeatedly - assuming the coin switch is working properly. Flick the roller upwards as if there were a coin passing thru the slot. If you do it too many times, the machine will code, then you reset it.

This is a good way to determine a bad coin switch. If flicking the lever doesn't have any effect, your problem has to do with the switch making the connection to the logic, thru the rear connection and so on.

[rjpohl]

I tried pressing coin switch at least 100 times,  bell still ringing and hopper is jerking. 

When I turn on power this is what I have:
Diverter below coin acceptor pulls in
Coil to release Hanke pulls in, I can pull handle but reels lock up real fast  ( before spinning) and handle will not return.
The tilt, coin accepted and deposit coin lights are light.

Thanks for the help guys.  I must just be overlooking something.

[rjpohl]

can some one verify which way the ribbon cable connect between i/o and mpu?  There is a red line on one side of the cable, I've tried it with red up on both and w/red down. 
thanks for your help and time with this.

[rjpohl]

thanks remegoom for the pictures, my i/o is the same as yours but the connection on the mpu is located vertically and in a slightly different spot.  maybe some one else can confirm connection to mpu.
thanks
Bob

Looking at the MPU board there is an IC located between the socket and the dip switch. Look closely at the IC and you will see a small notch
(u shape) this indicates that pin 1 of the IC is the top left pin. The red stripe of the cable should be placed so it is closest to this IC

The I/O board you can also look to see the notches on the IC's, in this case they are all point towards the top of the board (as oriented
in your photo) the red stripe of the cable should also be pointing in this direction.

This seems to be opposite of what ramegoom is showing

[rjpohl]

thanks Dan, I'm pretty sure that's how I have it but I'll double check in the next day or two.
karma to all that have helped

[ramegoom]

dhellis, I am going to check the machine to see if it' s right. I just opened one machine for those pic's, didn't verify it...

Thanks

[dhellis]

I am wondering why my other post didn't show up, the one where I realized that my cables are built wrong. Ramegoom, I think your
photos are correct, just looks odd to see pin 1 on the socket with a different orientation than the IC's.

So I took my ohm meter and an MPU board, pin 1 is BD0 which comes from pin3 of U8 so the red stripe on the MPU board
goes DOWN

Next I did the same on an I/O board and Pin 1 of that socket (J5) is attached to pin 3 of U17 so the red stripe on the I/O board
goes DOWN

The MPU board in your picture (ramegoom) is an E2000 board, the socket is oriented differently but I was also able to determine
this by the DK03 transistor and 2 watt resistor up by the display socket.

On the E1 MPU board you would rotate the I/O socket 90 degrees to the right.

[ramegoom]

I suppose the beveled edge of the socket always lines up with pin 1, which always lines up with the red stripe.  That's probably the best way to spell it out.

That and I noticed for the first time a white half circle at the bottom of the sockets. Geesh, I must be getting
old not to have seen that before

I've been extremely busy the last few days and have not had an opportunity to work on this project.  Hope to do so early next week.
thanks

Just mounted the repaired mpu and i/o boards. 

With reel assembly out I can get the machine to reset (tilt light goes off, coin diverter is pulled in, deposit coin light is light.
As soon as I put reel assemble in the coin diverter will open and the lights in the top box start flashing.
I can not get the tilt to clear until I remove the reel assemble.

With the reels out and the tilt cleared if I flip the coin in switch the coin diverter will open and tilt light comes back on.

Pushing the test switch does not enter the test menu.

Any suggestions
Thanks
Bob

[dhellis]

Have you checked the two switches on the left hand side of the reel mechanism? The top switch is the Arm Switch and is normally open
and closes when the arm is pulled. The lower switch is the kick switch and is normally closed. It opens when the arm is pulled and
then closes as the handle is released.

You can test these by running test 3 and when the kick switch is operated you will see the 010 code in the window and 020 for the
arm switch. While I'm at it code 001 is the coin switch, 002 is the hopper switch 008 the door hinge switch.

[rjpohl]

Dan you were dead on, the Arm Switch was wired wrong, normally closed, i moved the lead to make it normally open and it now accepts coins.
I do have several problems that I need to address.  I need the 1/2 gear (it has some teeth missing) and the bushings for it).  I also need a hopper.  I'll be putting a post in the classified shortly

thanks again for all that helped with this repair.  Thanks to dhellis for repairing the mpu, i/o and power supply.  I suggest you contact dhellis if you have boards that need to be tested or repaired.

YIPPEEEEEEEEEEEEEE!!!!

[rjpohl]

OK, moving on to the other issues:
I now have it accepting coins and the reels spinning and stopping (had to replace 2 reel readers).

It does not pay off properly.
I ran test 5 and the 2 attached pictures show the actual reel position.  Pic 1 meter reads 1.2.4.1. . . Pic 2 metere reads 1.4.5.2. . .Does anyone know the codes for the symbols? (7, bar, orange, plum, bell, cherry)

I also ran test 6 and reading is 500788, is this correct for E-1090-1?

thanks
Bob

[dhellis]

The game eprom is correct for the E1090-1, the matching reel strips would be M231-28, 29, 30

The code 7 should be 3 bars

*Edited*

C= Cherry
1 = Orange
2 = Plum
3 = Bell
4= Melon
5= 1 bar
6= 2 bars
7= 3 bars

Hi Dan,
500788 is the correct chip number?
not sure that I understand what you mean about code 7 should be 3 bars.
In the first pic the meter reads 1 2 4 1 (it's my understanding the the 1 = payline 1, 2 is the symbol on reel 1, 4 is the symbol on reel 2 and 1 is the symbol on reel 3.  Do you know what the symbol codes are?

thanks
Bob

[dhellis]

Your assumption is right.

1 is the first pay line, then 2, 4, 1 are the symbols that should be showing. I just realized that I took the codes off of my E809
which has a label. I would think that these are standard but maybe not because none of those are what is showing in your
window. The list also does not show anything for the '7' symbol

[Jim]

Bob,  not all the games are standard, best way to determine what is real and what is bad:  pull the reel mech out about half way, now reach in the back of the reel mech and move the reel stop out of the way (don't lock it in place) now move the reel to align the cherries on the first two reels( then let the locking stop lock the reel in that position), you should see a small circle on the correct reader, then go through and do that for each symbol, and you should be able to determine which symbol corresponds to what number for that machine.

Hope this helps

Jim
