Class 2 Alarms
These are caused by hardware faults on the MPU5 board. Most alarms of this class are generated during power up self-test.

2x red 5 x green is a display error

double check all wiring is correct etc

Hi ya, this sound like a boot chip problem, most barcrest machines a very reliable and this fault only really happens if the game card becomes loose or the boot chip ( pic chip ) is the wrong version, you say you swapped over your mpu and gamecard, did you change the eproms yourself and if so did you make sure there were the right way around if not you may have fried them too.

Good luck with your machine and if you need anymore help feel free to ask, just for your information ive worked in this trade since a lad so i got 12yrs of xp and i now own my own gaming machine company, just so you dont think im guessing at your problem
