Hi inspectorsudoku
there is a switch in currieddog 's snippet of schematics (post-2) --- named "Shut Off" --- ipdb has no good picture to Capersville - I have taken "Shangri La" - encircled green: There is a bolt sitting below - jumping up when we bang upwards onto the plywood - bolt jumps up and the "Shut Off Switch" opens. Look in Your pin for such an switch on the bottom board - all good ? Greetings Rolf
