Voltages can be checked off load or on load-

if the pump is disconnected it's off load - so you would get battery voltage, if not exactly battery voltage then a connection problem

If voltage on load (pump connected) then the voltage can drop a bit , but too much means the pump is knackered - dragging down the volts or filter blocked , making the pump work harder

Y ou can use a bulb and 2 pieces of wire to simulate on load ( if bulbs big enough) and check if the bulb dims compared to straight across the battery
