[QUOTE="Sharpend, post: 513932, member: 17152"] To do the continuity test you will need to disconnect all power inc battery. remove suspect cables one at a time from panel and attached sensor. Connect two cores together at one end. Set multimeter to ohms (resistance symbol) touch a test lead to each of the two corresponding cores at the panel. You have now completed the circuit with your tester and should get a test result, ideally you are looking for “0” or a continuous beep sound. This would indicate a closed circuit. Now separate the two cores at sensor end and test again at panel. This time you should get no sound and a high reading on your multimeter. This is a result of an open circuit. this concludes the test of the two cores, you can reproduce the test on any two cores to prove that the cores are continuous when joined and separate when not. whilst not definitive in itself it gives a good indication if the cable is faulty.
