How can I find out what my water pump problem is?
Ultimately using some simple electrical tests the homeowner traced the water pump problems to a nicked well pump wiring circuit wire. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need.
What does abnormal resistance on water pump wire mean?
Abnormal resistance on pump circuit wires (with POWER OFF so we don’t get fried) an indicate a shorted or grounded wire (zero or abnormally low resistance) or an open circuit (broken wire, high or infinite resistance) So we could argue that a pump running against a waterlogged pressure tank might see higher than normal pressure but I doubt it.
How can you tell if a well pump motor is dead?
If the well pump motor is dead or the wiring insulation has been destroyed you will see less than 10,000 Ohms resistance. You can also check resistance between each lead and ground – and to the well casing as sometimes that will show up a short not between wires but between one wire and ground.
How big is a well pump Wire compared to a pump AMP?
Well Pump Wire Size vs Distance (typical) Distance to Pump Pump Amps Typical Wire Size (AWG) Typical Wire Size (AWG) Distance to Pump Pump Amps 120VAC 220VAC 0-50 ft / 20A 12 14 50 – 100 ft / 20A 12 14 100 – 150 ft / 20A 10 12
How can I check the voltage of my fuel pump?
Establish the location of the fuel pump relay on the dashboard or the engine compartment. Remove the relay and have some one switch on the ignition without starting the engine. Check for voltage at the relay connector using a digital multimeter.
Why are heavy duty connectors used in a fuel pump circuit?
Voltage in the circuit is reduced “downstream” of the high resistance, so this reduces the voltage that reaches the pump motor. That’s why heavy-duty connectors are used in a fuel pump circuit. There are two fuel pressure specifications for every vehicle: system pressure and hold pressure.
How do you test a 3 wire well pump?
First, you will need to purchase an ohmmeter. Next, determine where the ground wire is in comparison with the additional three wires. Finally, use the owner’s manual to determine the wire resistance and voltage requirements. The testing between each wire to ground should match the owner’s manual exactly.
What should my fuel pump multimeter reading be?
Connect one of the multimeter sides to the battery and the other side to the connection that leads to the fuel pump. You should be careful not to test the wrong circuit. The reading on the screen of the multimeter should be 0.1.
