Easy: make sure both ends of the cable are completely disconnected. Go to one end of the cable, twist 2 cores together for instance brown and blue. Now go to the other end of you cable and test the continuity between the brown and the blue cables. This will verify both of these cables are continuous.
Now untwist the cables, and twist another pair together, say brown and green/yellow. Test again between these cable and you're done.
If you are fault finding, you can use this to figure out which cable is broken.
Say you get no continuity between brown and blue.
Set the test up again, test brown to green/yellow and you get nothing again.
Set the test up again, test blue to green/yellow... assuming you get a continuous signal here you can assume you have a problem with your brown wire.
Continuity in a circuit means no breaks; continuous.
Electrical continuity denotes that the current from the source is successfully reaches the negative terminal. If there is no continuity means, the current will not flow through the circuit.
A typical multimeter can measure: * AC & DC voltage (volt) * AC & DC current (amp) * resistance (ohm)
You can use an ohmmeter or continuity tester. Connect one lead to ground and the other to each of your sensor wires. When you have a ground on the wire being tested, your meter will indicate continuity. Make sure the sensor wires are de-energized when testing with these methods, this may require you to disconnect the system power and unplug the backup battery. If you already know which wire is grounded, you'll need a transmitting/receiving device such as a circuit tracer or short tracer. This device will allow you to follow along a wire and detect approximately where the problem is.

Use the continuity test facility , I have information on my website and links for testing and inspection http://www.rbgrant.co.uk
To test doorbell wires, use a multimeter to check for continuity and voltage. Disconnect the wires from the doorbell and transformer, then test for continuity to ensure there are no breaks in the wires. Next, test for voltage to ensure the wires are receiving power. If both tests are successful, the wires are functioning properly.
To measure resistance, and to check continuity.
To conduct a furnace pressure switch test, you will need a multimeter. First, disconnect power to the furnace. Then, locate the pressure switch and remove the wires. Set the multimeter to measure resistance and test for continuity across the switch terminals. If there is no continuity, the pressure switch may be faulty and needs to be replaced.
A device to test if wires are electrically connected. Typically a small lightbulb and a battery are used.
A: Checking continuity is the same as checking resistance, therefore yes someone can determine the resistance at that particular current level
To test electrical wires for proper functioning, you can use a multimeter to check for continuity and voltage. Make sure the power is off before testing, and follow safety precautions. Check for continuity by touching the probes to each end of the wire to see if there is a complete circuit. Test for voltage by setting the multimeter to the appropriate setting and touching the probes to the wire to measure the voltage. If the readings are within the expected range, the wire is functioning properly.
To check continuity in a long wire, use a multimeter set to the continuity or resistance mode. Connect one probe to one end of the wire and the other probe to the opposite end. If the multimeter shows a low resistance reading or beeps, it indicates that there is continuity in the wire. If there is no reading or beep, there may be a break in the wire.
Get a voltmeter Set it to OHMS scale touch the two leads together--needle should run full scale indicating continuity (wires all connected) same wire indicating NO RESISTANCE If you test for continuity-you are looking for no resistance= wire continues
you can take a siren from a home security device, not a speaker but a siren cause a siren works of voltage and a speaker works of wattage. take a battery that is capable of working the siren then just put the the siren in series with the battery and then take the two wires and put one on the open side of the battery and the other wire on the open side of the siren. If the siren goes off there is continuity between the two wires your testing if the siren dont then there is no continuity.... good luck..
Locate the wires that run to the wiper motor and check them for continuity. If not that, hot-wire direct from the battery to those wires to see if the motor is burnt out.
To check continuity in a fluorescent light, use a multimeter set to the continuity test mode. Remove the fluorescent light from the fixture, disconnect the wires, and touch one probe to the live end and the other probe to the neutral end. If the multimeter beeps or shows a low resistance reading, it indicates continuity, meaning the light is functioning properly.
