Quoted from TecumsehPlissken:I suppose this thread is as good a place to ask as any before starting a new thread. I have a sort of similar question. How come I can measure a coil/relays resistance before installing it in a Gottlieb EM & it measures approx. 15 ohms , but once its wired up and installed it only measures .04 ohms ?? replaced it because it checks bad but ONLY when its installed?
Because other things like switches and other coils are now in the circuit too causing false readings.
