A was just re-reading the thread. So this is the same problem you had originally that was fixed?, and now has started again. I would double check all switch tests again. Test every thing, making sure the correct switch is triggering against the manual. Also do the same for the Solenoid test.
Also have the connectors been redone or original.
To test your switches you could desolder and meter them to see if the open/close.
It may also be the switch matrix. You may find all the switches on the same
Matrix Line or row, are not working. Could
Be a bad solderjoint, broken and loose wire, connector.
