Sorry for the dumb question.
Where at the pump to I check its getting the correct voltage. Car has been stood for a couple of years so just giving it the once over.
Do I check at the 2 terminals at the pump, should I get voltage between these 2 wires or between one and earth. Obviously don't want to disconnect one to test as the pump will stop running.
What's the easiest way to check it?

Thanks.
