unplug the wires and have a check inside the plastic plug.One of the little legs should be oxidate.There was a recall for this problem.I just fix mine.

What could be the problem on a 94 shadow 2point5L ES-its not pumping fuel-no voltage to the pump-it did work- there is gas in the tank- please help?
If there is no power to the pump, it must be a fuse or relay that is out. The relay is the first relay from the front of the car on the drivers side.
Wire to electric fuel pump has low voltage?
if you have checked the voltage with a dvom then you need to verify that the power source at the fuel pump relay is correct, if it has the correct voltage pre-relay then your problem is post-relay. if the voltage is not correct pre-relay then simply trace and repair the power source. if the problem is post relay then check the output voltage directly at the relay, if voltage is good trace and repair line from relay to pump. if voltage is not correct then replace the fuel pump relay
Drop out voltage of a solid state relay?
Typically, when the coil voltage on a relay is decreased gradually, the relay "hold" will release at a certain voltage. This is usually defined as the Drop-out voltage (defined at some minimum value). Now, in the case of latching relay, the Drop-out voltage is called the Reset voltage.
What is Under voltage relay?
Under voltage relay provides a signal (Contacts) when the supplied voltage drops below a preset value.
What voltage does a potential relay operate from?
The voltage for a potential relay will depend on the circuit that the relay is installed in. The relay can be made for low voltages (5v) to higher voltages (440.)
What happens when a relay is operated beyond its rated voltage or current?
Generally speaking, a relay is an electrically operated switch. As such, there are two sets of ratings associated with a relay. The operating voltage will be specified, and the ratings of the contacts are also set down. As regards exceeding the operating voltage, this will cause excessive current to flow in the relay when it is energized. If the voltage is not significantly higher than the rating, and if the relay is not operated often or for long, it will function normally, but probably with a shorter life. At some point, excessive operating voltage will cause the coil in the relay to fail. Operating a relay to energize an electrical circuit with a higher voltage or current than the relay is designed for will shorten the life of the contacts in the relay. Higher voltage and current will quickly burn the contacts and destroy them. This is particularly true if that voltage or current is significantly higher than the ratings set by those who designed and constructed the relay. Things might work for a short time, but not for long.
What is the function of monitoring voltage relay?
A voltage monitor relay is in the circuit for one reason. It monitors the incoming voltage to the equipment that it is protecting usually on three phase control panels.The relay monitors the three incoming line voltages and in some relays the voltage to ground (wye connection). If the circuit the relay is protecting looses one of the voltage legs, the circuit will shut down until the problem is rectified. This usually happens if a fuse blows in one of the three phase voltage legs.It also monitors the level of voltage to the circuit. If the voltage drops due to a malfunction in the utility lines the relay will trip and take the protected circuit off line. The voltages can be set to trip at any under or over voltage usually by set point controls on the front of the voltage monitoring relay.
What is the number on the Reverse Voltage Protection Relay for a Ford Contour '97?
On a 1997 Ford Contour : The Reverse Voltage Protection relay location is marked ( D1 )
Is a resistor and a relay the same thing?
No, they are not the same. A resistor is a current reducer and a relay is essentially a switch (using low voltage to switch high voltage on/off)
What is PCM relay?
PCM means Powertrain Control Module A relay is a low voltage switch
Where is the voltage relay on your 1991 dodge b250 van?
voltage regulator is part of the engine computer
How do you check the under voltage relay?
The way you check to see if an under voltage relay is wired properly is to disconnect the electrical supply. If the device that is connected to the load side of the relay does not start up or energize when the electrical supply is reconnected, then the relay is connected correctly.
