Unfortunately, that only checks part of the circuit.  It won't tell you if
the wire to the PDWA switch is disconnected or broken; or if the PDWA switch
doesn't work, or the piston is stuck.

My light works fine, but the wire to the PDWA is MIA.  Not sure if it broke
or was terminated with prejudice by a previous owner, but it's gone.
