IGT Triple Lucky Sevens Coin-In error

[montech]

Ok
I haven't seen this one before. Clear the game , key it everything ok. Have my IGT molex jumper in place for no coin mech. Sets up fine for limits ,everything. As soon as you put a bill in the BV it registers the 20.00 and gives you a coin in error. Clear it again and it will sit there forever until you put in a bill in the BV. Then coin- in error. I was getting a coin in jam/ meter disconnect until I replaced door I/O and cabinet I/O. Could this be a bad MPU?

Thanks for all the help. Even I path to follow would be appreciated.

Haven't we seen this trace back to one of the NetPlex devices?  What's the history on the machine? Been up and running fine or is this a new one?

Make sure you don't have any bent pins on the door and cabnet I/O cards

Just for giggles, try pulling that BV and starting the game without it...and then let it sit for a few minutes.

I would gently push in the MPU tray after you re-insert it.
I had similar errors on my S2000 after changed games or such that cleared easily after double checking that the MPU was fully seated into the motherboard.

Hello everybody
Thanks so much for your input. Hope everyone had a great holiday.
This is a machine just in to be shopped.
Question:
I have been told that we cannot use 14930203 and 14930200 I/O boards in the I960 MPU  board games. I was told to use the 14928001 and 1492800 for S2000 with I960 board.
The machine came in with the first set in it. I did repair a bent pin on the 14930200, when it first came in, but didn't make a difference. Now I get a hard coin error no matter what.
COIN IN JAM

Hmmm
Anyone know the part number for a 10 button I/O board?

I think the part numbers you're list in  are coming off the board case and not the board itself. The common IO board for those will have a number on the board itself that ends in 7802.

Yes, there is a number on the metal casing/housing around the green board, and then another on the green board itself. You need to look at the number on the green circuit board itself.

I have these off a GK...

P/N 75427630 (Cabinet) & 75427830 (Door


And these off a dual row...but this is the one in the black housing...

P/N 14940201W

Thanks CV, everyone!
Apparently this is my problem! Wrong I/O installed in the game.

Let you know when I get one installed.

Glad you found it! Let me know if you need an I/O. I'm sure we have them!
