Thermostats are not electrical devices so I am assuming you are referring to a temperature sender. To test it unplug it with the motor off and cold and use an ohm meter between the two connections on the sender, it should show infinite ( closed circuit ) resistance. Plug the sender wire plug back on and start the motor. Let the engine run until it is warmed up. Shut off the motor, disconnect the sender again and retest with the the ohm meter, the resistance should drop and show an open circuit. Note that if this sender is a thermo time switch the test I described will be incorrect.
If you really are trying to test a thermostat the way you do it is take it out of the car ( with engine cold )and look at it. If it is not closed it is faulty. Put the thermostat in a pan of water and heat it up while monitoring a thermometer to the temperature stamped on it. If it does not open at the designated temperature it is faulty.
I would suggest you buy a repair manual for your vehicle to help you identify wich parts you need to test. Most of them have troubleshooting tips and tables to help you figure out what is wrong with your car.

What is the difference between continuity and resistance check?
Continuity check tests if there is a complete path for electricity to flow between two points, indicating if there is a break in the circuit. Resistance check measures the opposition to the flow of electricity in a circuit, providing information about the quality of connections or components.
What best describes continuity in a circuit?
Continuity in a circuit refers to the unbroken path for the flow of electric current. It ensures that there are no breaks or open circuits that could interrupt the flow of electricity. By testing for continuity, you can verify that all the components in the circuit are properly connected.
What does the values of continuity test indicate?
1) A continuity tester is a simple device consisting of two testing probes and a light (LED) or buzzer indicator. It is used to detect the presence of continuity or a break in between the two ends of a conductor which is connected to its testing probes. For instance, if the two probes of a continuity tester are touched to the two ends of a wire bundle, its indicator may get activated to confirm that there is no interruption in the continuity of the wire and everything's fine, or, if the indicator shows no action it would mean that there's a break in the continuity of the wire and needs attention. It may also be used to trace out faults in complicated electronic.
How can you calibrate your electric heat thermostat?
There are two ways to do this. Fist is there is a small nut located behind the heater coil on the thermostat. It takes a special wrench to turn this nut. You can get them where you buy your thermostat. The second way is to back off the screws that hold the backer plate to the wall and check it for level. Once it is level tighten the screws and connect the thermostat back to the backer plate.
Why does the thermostat keeps turning on and off?
Because that is its job! A thermostat is a device that measures the temperature of a given space or volume, and turns heating / cooling devices on and off accordingly. The thermostat in your house is designed to turn the heating off when the house is warm and turn it on when the house is cold. The thermostat in your car turns the radiator fan on when the oil / water temperature increases to a level that could be damaging to the engine (if you are stuck in traffic for example)
How can I test a refrigerator thermostat to ensure it is functioning properly?
To test a refrigerator thermostat, you can use a multimeter to check for continuity in the thermostat. Set the multimeter to the ohm setting and place the probes on the thermostat terminals. If the reading shows continuity, the thermostat is functioning properly.
How can I test a hot water heater thermostat to ensure it is functioning properly?
To test a hot water heater thermostat, you can use a multimeter to check for continuity in the thermostat. First, turn off the power to the water heater. Then, remove the access panel to expose the thermostat. Use the multimeter to test the thermostat's terminals for continuity. If there is no continuity, the thermostat may be faulty and needs to be replaced.
How can I test a dryer thermostat to ensure it is functioning properly?
To test a dryer thermostat, you can use a multimeter to check for continuity. Disconnect the thermostat from the dryer and set the multimeter to the ohms setting. Place the multimeter probes on the thermostat terminals and check for a reading of zero ohms, indicating continuity. If there is no reading, the thermostat may be faulty and needs to be replaced.
How can I test the thermostat on an electric water heater?
To test the thermostat on an electric water heater, you can use a multimeter to check for continuity and proper functioning. First, turn off the power to the water heater. Then, remove the access panel to expose the thermostat. Use the multimeter to test the thermostat's terminals for continuity. If there is no continuity, the thermostat may be faulty and need to be replaced.
How can I perform a test on a dryer thermostat to determine if it is functioning properly?
To test a dryer thermostat, you can use a multimeter to check for continuity. Disconnect the thermostat from the dryer and set the multimeter to the ohms setting. Place the multimeter probes on the thermostat terminals and check for a reading of zero ohms, indicating continuity. If there is no reading, the thermostat may be faulty and in need of replacement.
How can I test an electric water heater thermostat to ensure it is functioning properly?
To test an electric water heater thermostat, you can use a multimeter to check for continuity and proper voltage. First, turn off the power to the water heater. Then, remove the thermostat cover and use the multimeter to test the thermostat terminals for continuity. If there is no continuity, the thermostat may be faulty and needs to be replaced. Additionally, you can check the voltage across the thermostat terminals to ensure it is receiving power. If there is no voltage, there may be an issue with the electrical supply to the thermostat.
How can I conduct testing on a dryer thermostat to ensure it is functioning properly?
To test a dryer thermostat for proper functioning, you can use a multimeter to check for continuity. Disconnect the thermostat from the dryer and set the multimeter to the ohm setting. Place the multimeter probes on the thermostat terminals and check for a reading of zero ohms, indicating continuity. If there is no reading, the thermostat may be faulty and in need of replacement.
How can I test a water heater thermostat to ensure it is functioning properly?
To test a water heater thermostat, you can use a multimeter to check for continuity and proper voltage. First, turn off the power to the water heater. Then, remove the access panel and insulation to expose the thermostat. Use the multimeter to test the thermostat's terminals for continuity and voltage. If there is no continuity or incorrect voltage readings, the thermostat may need to be replaced.
How to test a thermostat to ensure it is functioning properly?
To test a thermostat, you can use a multimeter to check for continuity in the thermostat's contacts. You can also submerge the thermostat in hot water to see if it opens and closes properly.
How can I check thermostat wiring?
To check thermostat wiring, first turn off the power to the thermostat. Remove the cover and inspect the wiring connections to ensure they are secure and not damaged. Use a multimeter to test for continuity in the wires. If there are any issues, consult a professional for further assistance.
How can I test thermostat wiring effectively?
To test thermostat wiring effectively, you can use a multimeter to check for continuity and voltage. Make sure to turn off the power to the thermostat before testing the wiring. Check each wire for proper connections and ensure they are securely attached to the correct terminals. If you are unsure, consult the thermostat's manual or a professional for guidance.
You have to jump start your epg 250 by shorting out the gas valve coil to th terminal or th-tp terminal to th terminal it starts right up. Why do you have to short out to get it going?
It means that you either have a bad thermostat or bad thermostat wires. You can also check for continuity in the thermostat wires with the thermostat on.
