It sounds like you may have a problem with the fuel pump or the wiring related to it. The 5-volt reading suggests that there could be an issue with the fuel gauge sending unit or a short somewhere in the wiring harness. Additionally, check the fuel pump relay and any associated fuses, as they could affect the voltage being supplied. Ensure that all connections are secure and that there are no grounds or shorts in the system.
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
Just checked and it does have a ground connection.
How many inches of the ground can my car be if dropped
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
Because the O'scope and the device being checked must somehow be sharing a common ground. That may be good, bad, or indifferent, depending on the electrical sensitivity requirements of the device being checked. It won't harm a quality O'scope.
I accidently dropped it on the ground!
In a 277-volt circuit, if you measure the voltage from Phase 1 to ground, you should read approximately 277 volts. This is because 277 volts is typically the line-to-ground voltage in a three-phase system where the phase voltage is 480 volts. Therefore, when measuring from the phase conductor to ground, the voltage remains the same at 277 volts.
5 volt supply, sensor ground and signal voltage.5 volt supply, sensor ground and signal voltage.
Voltage is the potential difference to the ground. By convention, ground potential is zero volt.The above answer is incorrect. 'Voltage', by definition, is potential difference. It has nothing to do with being measured with respect to ground -in fact potential difference (voltage) cannot be measured with respect to anything.
The neutral to ground voltage in electrical systems is important because it helps to ensure the safety of the system. When the neutral to ground voltage is at the correct level, it means that there is a proper connection between the neutral and ground wires, which helps to prevent electrical shocks and fires. Monitoring and maintaining the neutral to ground voltage is crucial for the overall safety and functionality of an electrical system.
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
as done in Galileo's experiment when he dropped a large rock and a feather from a tall tower both hit the ground at the same moment when dropped from the same height.
