From the instructions from the kit:
"The shield is set by connecting the pump to a voltage supply of between
6 & 12V. Positive earth pumps must be connected withe the Positive wire
to the pumps body terminal. Negative ... (DNA) ... Place the shield
adjustment tube <just a short plastic tube> over the shield finger and
hold the pump securely, briefly touch the terminal bolt on the circuit
board with the other battery lead. At the same time move the shield in
towards the magnet. The pump should begin to make a faint audible
click, as the magnet rises and turns on the hall switch (which turns on
the solenoid) then drops back.
If the magnet rises to full lift and stays there, either the shield has
been moved too far in or the solenoid internal connections are connected
in reverse."
FWIW, I believe these pumps are tested at the factory after assembly. I
gotta believe it's not the pump, but don't know what else it could be.
