Hi Guys,
looking for a bit of tech help on a switch matrix issue which is always a ballache. I have judge dredd and switch 25 top right post always triggers another switch when closed namely switch 75 top ramp exit, which is an opto and both of these switches are in the same row. It does form the classic square with another nomally closed switch ie 76 right ramp exit (another opto) and the 4th in square is the captive ball 1 switch no 26. I have tested all the diodes on the 2 physical switches in situ and they seem ok so I am a bit stuck.
HELP!!!!
Cheers

EDIT - problem solved!! although i had checked diodes and diode orientation - failed to notice switch 25 had the row wires on wrong side of diode - problem solved!!!!
these things are so easily missed - lesson learned!!
