If you put your MPU and chips in his, that doesn't rule out the backplane in your problem cabinet.

Vice versa, if he throws his stuff in your machine, you don't know if your chips or MPU is any good.

What model MPU and backplane board do you have in there?

ThirdGenAmusement · « **Reply #21 on:** October 27, 2020, 09:25:00 PM »

MPU is the 1270 enhanced. There is nothing in the rev block for the board so not sure which it is. The backplane board is a 75909100 Rev EB.

Here is something easy to try, unplug the coin mech. main harness and install the jumper plug and see what happens!

That's a good thought.

I totally agree with you guys and it WAS suggested to do this in Reply #3 but this fella probably doesn't have one? Idk

Hello!
So.... things started to look up for a bit. The issue with the coin-in error was being persistent and tried a few different things including changing out the board set and mother board. Unfortunately no change. The only thing that made a big difference was the fact I discovered I had an 802 i/o card in place of an 801 card(this machine has 2 i/o cards so it was the one at a 45 deg angle between the belly glass and main door). I have 2 extra 801 cards so I tried the first one and it may have been defective since only some of the bet/line buttons lit as well as getting persistent coin-in error. So I put the other 801 card in things ran great......For awhile. I played the machine for a good couple of hours solid with no hiccups and thought it was repaired..... Then I got a coin-in error. Cleared right up with the door latch reset and played on for quite a while. Then another coin-in error. Now at this point, its back to being as bad as it was initially with not being able to clear the error or if I do its only for a pull or two before it errors again.
The machine would accept coins and bills so I don't feel as though it has to do with the comparator. One thing I have noticed is that the machine seems to do the error when the bv light turns on. So once the machine is powered on or a reset using the door latch the bv light will flash on then the coin-in error happens. There are times the machine is operable for a pull or two right after turning on or after the door latch clear is used if there is credits on the machine. But the bv light. the one that reads insert tickets or bills face up, lights up that's when the error seems to happen. If that light is lit and stays lit, I can input coins or bills. Hopefully this makes sense.
I may try to purchase a few more 801 cards and be sure that it wasn't another faulty card. But I am curious if there is something I can look for that might be taking out the 801 card since the 2nd 801 card I tried worked for a period of time and slowly became worse. I have replaced the power supply and even unplugged all the florescent ballasts to be sure they weren't giving issue after the first initial coin-in errors with this i/o card.

Thoughts appreciated! =) And sorry for the long post.

While you're spending $$$

on I/O cards, pick up a coin mech jumper plug too and try our suggestion?!

ThirdGenAmusement · « **Reply #27 on:** November 09, 2020, 07:10:46 PM »

Thanks Stayouttadabunker. Yes that's on my list to.

I apologize, I did forget to mention that I did try using jumper wires on the plug for the comparator/led area after a member here sent it to me and it still gave me a coin-in error. I believe that was either while the 802 card was installed it the first 801 card. When I put the 2nd 801 card in I thought "Whoo hoo!" Since everything seemed to work. So I didn't go further with trying the jumper then. But, the "whoo hoo" was short lived. Lol.

Stayouttadabunker · « **Reply #28 on:** November 09, 2020, 07:17:42 PM »

haha okay

An 801 I/O is for a single row of deck buttons.

An 802 I/O card is for decks with double rows of buttons.

ThirdGenAmusement · « **Reply #29 on:** November 09, 2020, 08:06:24 PM »

Gotcha. This having 2 I/o cards one is a 801 and the other an 802 or are they supposed to both be 802?

Stayouttadabunker · « **Reply #30 on:** November 09, 2020, 08:10:22 PM »

801 between the panel and belly glass.
802 on the panel facing to the rear of the machine.

ThirdGenAmusement · « **Reply #31 on:** November 09, 2020, 08:14:39 PM »

Thank you.

Make sure the 801 harness runs to the reel glass display by the door hinges.
The 802 harness runs back to the backplane board in the cabinet behind the MPU.

People mistakenly mis-connect these two harnesses.

ThirdGenAmusement · « **Reply #33 on:** November 09, 2020, 08:22:12 PM »

Thank you. Will double check.

Pic of the error

ThirdGenAmusement · « **Reply #35 on:** November 09, 2020, 08:55:29 PM »

I checked the wiring and its correct. 801 card(between belly glass and main door) goes to reel glass and 802 card(between main door and inside of cabinet) goes to the cabinet.

Tried to upload pics but apparently I reach my limit of pictures.

It seems that when the BV light comes on is what's setting off the [Coin-In Error] error code.
I'm wondering if the power supply is loose up there behind the reel shelf or if that power supply is flaky?

Could you pull the BV light harness out and play a few games and see if the error pops up?
That BV light draws very little amps but might be just what is maxing out the power supply for some reason?

Disconnecting that BV lamp and playing a few games without erroring might give you an answer?

We want to rule out everything....one component at a time until this topic is solved.

I use plain ol' Windows Paint program to resize the larger sized side of a photo (horizontally or vertically) of pixels to down to 1000 pixel, rename the photo & save it on my desktop temporarily until I grab it and place as an attachment in a Reply....>>>

ThirdGenAmusement · « **Reply #37 on:** November 09, 2020, 08:59:33 PM »

Will do! I appreciate the idea.

Early on I did swap out power supplies from a working machine.

I'll report back.

ThirdGenAmusement · « **Reply #38 on:** November 09, 2020, 09:32:52 PM »

Whoa.... This cant be the problem... BUT IT IS! Stayouttabunker....This was right in front of me and you found it!!!!

It ended up being the Board that holds the bulbs for the bv. A resister may have gone bad. I thought it was a socket but after trial and error the only way the machine would function properly is having both sockets removed even though the board was jacked. This may be the culprit that took out the 801 card.

Before calling this solved I will play it for an extended period of time but thanks for all the suggestions and time!

ThirdGenAmusement · « **Reply #39 on:** November 09, 2020, 09:50:42 PM »

I checked the resisters and R2 is internally shorted and I believe this is the problem!!! So I will either get another resister or different board.
