<VV> testing an electric fuel pump

[cfm]

So if I suspect a bad electric fuel pump, I would like to test it, can I use a battery charger? If so, is it as simple as clipping positive and negative on the pump to positive and negative on the clamps from the charger? Or do I need to ground off to something else?
I am almost done reassembling the fuel tank and related systems, and am cautiously optimistic that everything will come together just right.
always looking forward to the responses,
