Can anyone give me some help to test if my shurflo pump is OK. iTS NEW BUT BEEN STORED AWAY since May 15. as i didnt get to set it up. as a 2 man setup. I set everything up the same as my other regular shurflo pump. Controller comes on so its powered up to battery. Pump shows no power at all. Anyone had this happen to them. Can i test the pump some way. Waterflow is coming from water tank, but the pump has no power to suck. Can anyone help to see if i can get it powered up.
