Put an ohm meter across the coil and read the resistance. Usually they are quite high depending on the voltage and the size. If you can compare with an known good one then you can know what to expect give or take say 15%. If there is no reading it is open circuited and if it is very low then it has a short within it. Some times the smell will show a short.

Is a relay considered a load?
The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
What is the application of normally closed relay contact?
There are numerous applications for a normally-closed relay contact. It is used whenever you want to disconnect a circuit when the relay coil is energised.
Why do you put a diode across a relay coil?
If the current through a coil is interrupted, the coil generates a high voltage (such as in the old car ignition coils). The diode provides a path for the current to decay naturally, thus avoiding the high voltage.
A device that opens and closes a set of contacts when its coil is energize?
The device is a relay. A relay may have several sets of contacts, or sets of open and closed contacts that "change state" as the coil is energized.Changing state means that the normally open contact will close and the normally closed contact will open when the coil is energized.
Why SL100 used to energize a relay?
SL100 NPN transistor can provides enough current gain (500mA) to drive the relay coil. So when our relay coil is drive by proper current & voltage it will works. For more info about SL100 please read manufacture datasheet. Wireshark Cookie Dump: OKCancel
1994 ply sundance no power to coil?
check the ASD relay
Why does the ac relay on the compressor clutch keep blowing fuses?
You may have a bad compressor clutch coil, you need to check the coil and work from there................
Where is coil relay on 1986 ford eco van?
There is no such thing as a coil relay.
How do you know if your coil is no good?
I assume you are talking about the starter relay or solenoid coil. If the engine is cranking but not starting, the coil is most likely good. If Nothing happens, check battery voltage at the coil. If voltage is present, coil (winding inside the solenoid or relay) is most likely bad. If no voltage present, then check for corrosion, loose terminal fittings, or any wire or cables that go from the battery to the starter.
What is a relay coil?
Most relays have an internal electromagnetic coil that is energized when the relay is activated.
What would cause a 1994 to start and run fine and then not start I have replaced the coil with no success.?
Did you check to see if theres any spark from the plugs after it wont start... if no spark check to see if the coil is getting power, if not then check the ASD Relay on the fender near the battery. Theres like 5 relays there... The ASD relay cuts power to both the Coil and Fuel Pump.
What is a control relay coil?
Most relays have an internal electromagnetic coil that is energized when the relay is activated.
A 2002 rodeo it is hard to start you get started it will idle but dies.?
check ur coil pack or relay fuse
What could cause a relay coil resistance to be lower than specification?
A short within the relay coil itself.
How can you test relay if good or bad?
To test a relay, first disconnect it from the circuit and use a multimeter to check for continuity across the relay's contacts when the coil is energized. If the multimeter shows continuity when power is applied to the coil, the relay is functioning properly. You can also listen for a clicking sound when the relay is energized, indicating that the contacts are closing. If there's no continuity or the clicking sound is absent, the relay is likely defective.
What is percentage bias relay?
This is basically a differential relay that contains an additional restraining coil with the operating coil connected at its midpoint used to prevent the unnecessary pick up of the relay.
What is transistor relay driver?
a transistor circuit for driving the coil of a magnetic relay.
