Hi,

... and all ball are in the thru. In switch test, the thru 1 square is not displayed as the ball relies on the switch, and the switch is new.

Continuity of tbe wires or switch matrix pb ?

thanks for the help

Hi, thanks for responding. I had the problem with the former microswitch. I thought it was coming from that part and replaced it by a new, but the problem remains. For me the microswitch and connections onto it are not a problem as the pin was working fine a while ago.

Nothing else on this one ?

Hi,

no it does not fire, although it looks ok when measuring continuity with the DMM. so I was thinking of another problem like wiring. I presume the test mode uses the switch matrix as well.

what do you think ?

thanks Butch, The pin is at a friend's home, it will come back soon to my little workplace, I ll check then. Have a good day

found. a broken wire in the row line ....
