well hno, in this case as you do not have the original value (since that depends on the circuit) you must perform a test with the energized equipment by placing a variable resistance (20 k potentiometer) and vary until you can activate the card, once Activate, disassemble the potentiometer and measure the value in which it was ...... It is already a little more technical test.
Another thing that can guide you is by measuring the pipe sensor, one of the two is usually damaged, and the value of the other can be referential ..... but EYE are not necessarily of equal value, only by experience I have measured them and for the most part they have given me equal value .......... I don't know if I explain myself ???
