Any error codes on a BF machine starting with 2 are the reels,
23 is reel 3 and where to start looking.
Check the plug to the reel is fitted correctly as it is easy to miss out one pin on those plugs.

Have you checked nothing is catching/obstructing the reel from spinning free when the door is closed, eg loose wiring,bulb masking, etc.

Does it show in the display Which alarm code it is?
Just a thought that if it was the power up alarm and just needs to be left till the machine resets.

Could be RAM corrupt so try a RAM clear,The Hopper level will need to be reset after a RAM clear though.

It could be the Mars mech has a program fault,try replacing the mech to eliminate it.

It won't be an easy job if you have no tech experience on machines. It involves removing the program card,disconnecting the plugs on the MPU,removing the cover from the MPU,locating the battery of which needs to be shorted to clear the machines memory. This does not damage the machine. The memory ca...

With the machine switched OFF,You will have to access the machines main MPU control board and short out the battery which is soldered onto the board.

Right.
Had one of these before and it has RAM corrupt as the machine thinks it has LESS than £1 in the bank to payout even though all the wins are payed in £ coins and has no 20p tube.
You will need to perform a RAM clear to get rid of that odd amount in the bank to sort it out.

Looking at your first post you say it displays .40 IOU which will probably mean it has a 20p coin tube and that is empty.You will need the 20p coins refilling. There will be a level switch attached with a rubber band to the 20p coin tube,the coins need to be kept above that switch.Or you could just ...

Having the diagram for the routing plug you should have no problems.

If you remove the power supply,There is a relay fitted to a small board situated on the underside of the power supply that triggers both 12volts and 50volts,could be that relay is at fault as they are a problem. Under normal operation on the MPU just the three voltage indicator LEDs should be on, th...

If you are sure the power supply is ok then i would try for a known working MPU. as the next step.

Very unlucky and unusual for the game card or the ROMs to fault,Only known game ROMs to fail(unless faulty when supplied) after someone handled them and static damaged the program. Not many good working Maygay M1 boards knocking about now,could probably be your replacement board is at fault too. Did...

Im having some real probs.Leds 1 to 7 lit,not doing anything,i know the power supply is ok so i got another mpu.sometimes it does nothing,other times it will make a horrible alarm noise and the reels flick and some lights flash.Variuos noises come from speaker but not music.some leds on mpu go out ...
