I have 36 switches on my layout. Twelve use DZ machines and are controlled by an SCI and SCII. Twelve of the remaining 24 are Lionel o22s, controlled by SCIIs. The last twelveare controlled by 4 IC Controls ASCs. These twelve switches have stopped working. The switches have power and can be operated by shorting the center switch connector pin to either of the side pins. The AscS are getting a healthy 14 volts. The command base led flashes when any switch is addressed from the CAB1. The TPCs and Block controllers which are daisy chained to the AscS seem to be working properly. I am at a loss as to how to further trouble shoot this problem. Any ideas?
