Why does your radiator fan relay voltage go from 14 volts unhooked from fan to 0 when it is hooked up?

Sounds like bad ground...
When using a voltage tester it does not draw enough to pick up whether you have a bad ground or not.. Then when you put a load on the circuit that is greater than that of the tester, the fan will not work if the ground is bad...

Where is the blower relay on a 1988 e 150?
The Relay is attached to the sheet metal that supports the Radiator and is located kinda between the Radiator and the Battery.....right next to the Voltage Regulator. It's VERY hard to see and get at......will probably have to remove the Battery to access it.
1994 dodge caravan and when its moving it doesnt overheat but when your stopped it starts to overheat and you notice the radiator fan does not come on is it the relay or?
It may be the relay or it may be the fan. Take a multimeter out and see what kind of voltage you are ghtting at the fan connection versus the realy. If you are getting voltage TO the relay and NOT OUT when it should, it's the relay. If you are getting voltage TO the relay and OUT of the relay then I would say it's the fan. You can run a jumper wire from a powered source and see if the fan spins and this way you know the fan is working if it receives current.
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.)
Where is the radiator fan relay fuse in a 1988 Chevy Celibrity?
The fan relay and its fuse are on the radiator support bracket on the right side of the car.
Where is the location of the AC clutch relay and the radiator fan relay on a 1993 caravan 3.3L?
check on the driver side lower corner of radiator.
Why does radiator fan relay fail?
When the radiator fan relay fails on a vehicle, it can quickly overheat due to the lack of cooling. The fan is designed to kick on at specific temperatures controlled by the relay.
Relay - Radiator Cooling Fan Motor?
The radiator fan relay is commonly located under the hood. Depending on the vehicle and model, the relay should be in a distribution box with the other relays.
