Apologies for the delay in responding ... I was wandering around the Mediterranean for most of July.

Is it possible to test pots without putting the solenoid board back? The board is still lying on my desk after the last attempt. Have decided not to try and rework the board again myself - last attempt got 3rd degree burns on my hand from the soldering iron and the thing didn't even work afterwards. Have a few options to try to get the board sorted/replaced so will explore them when time permits. Currently working 3 jobs with little free time.
