Hi everyone
Got a DIY project I need some help with. I know very little of motors & pumps.
I have a 12v water pump (link to pump: https://www.amazon.co.uk/gp/product/B00EIA8UPK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) that I'm running from a 12v SLA battery.
I have a hose connected to the pump and it draws water fine, however on one end of the hose I have a connector with a tap. When the tap is open and water is flowing freely the pump draws about 1amp (even though the amazon page says it should be 3 amps). When I close the tap, the pump cuts out after maybe 5 seconds however the current draw shoots up to 4 amps. It doesn't make any noise and sounds like it's safely cut off, but still drawing a lot of current?
Is this safe? This pump is going to be running in a car and the tap is definitely going to be closed for up to 5 minutes before I get back to to turn off the power supply to the pump.
Advice needed please
