I'm trying to help my niece out. She has a 2 wire with a ground submersible pump. It wasnt building pressure then it would back and forth then nothing now. I changed out the pressure switch and checked the pressure tank at empty. It was registering at 7 psi which Its suppose to be 28 with a pressure switch of 30/50. Tried to pump air into it and can't get it over 15 psi I assuming busted bladder also.
I have power going to the pump. 120v and 240v when contacts engage. Turned off power I ohmed the black and white wires from the pump wich I assume is l1 and l2. I got 3 ohms. L1 to ground- nothing and l2 to ground -- nothing. With contacts and power back on i amped draw 0.1.. well failure???? And the pump should still kick water whether pressure tank is working or not right?
