Hallo, the "Timekeeper RAM" on the Main-Module is empty and all Data should be lost.
"Spiel und Speichermodul" shoud be written on it...
It looks like this:

This one is from a "Turbo Sunny" and just an example picture, but yours should looks very similar!

Turn off your Slotmachine and pull out this Module, it's in a Box right in the centre of your Slotmachine.

At the Backside form the Module, you can find the Timekeeper-RAMs.
In most cases only the upper TK (Timekeeper-RAM) is improtant!
You have to replace tihs TK or mill of the empty lithium battery.
At this picture, I marked the TK you have to replace it:

Here a short Instruction:
The TK is a RAM with a Quarz for the realtime-Clock and a lithium battery.
If you mill it, DO NOT mill on the left side, because there is the quarz.
You have to mill on the right, where the battery is. But be carefull!!

Mill at the right side slowly and careful until you can see the battery-cell.

At this picture I already uncoverd the battery.

At the front of the TK are the two small battery conntacts which are going into the RAM.
Later we solder the new battery to this points.
You ONLY find the grond-connector of the Battery at the Pin outside. The positive-connector is not at the Pins outside.

If the battery is completely uncovered, you can unsolder the old one or you can use a fine cutter to remove the old battery.

Now you can solder two small wires to the new Battery.
If you can read the letters on the Timekeeper-RAM, the positiv connector is on the top and the ground connector on the ground. (as seen on the Picture)
Better you use a battery with solding-wires. You can't soilder on the battery surface direktly!
The new battery shoud be a lithium battery with 3V!

To fix the new battery, i use hot-glue.
If I mill TKs, I unsolder the whole Timekeeper-RAM and I put a IC-base so the TK is a little bit higher and the battery doesn't disturb other Parts of the module.

At this Pic, the TK has a new battery!

The TK has at the moment unlogical data and the clock isn't set:

I delete the TK with a "Prommer" (a Tool for the PC, to Read / Write on TKs and EPROMS) and I set the right time (time-set isn't realy important for most slotmachines).

At this Picture, the TK is mounted on the modul and ready to use!

Now we have to fix the "Foul_in"-measage.
You have to switch on the Slotmachine. When the "Foul_in"-message apperas, shortly connect PIN4 and 5 at the service-socket to initalize the module.
Look at the picture, it shoud count form down to top.

I hope, I could help you a little bit.
If you still have some problems, just ask
