hi, I've just bought a tank with the tube type balanced coil sender in it. I've stuck a multimeter across the positive spade and earth and filled the tank. The reading is changing but it's from about 5 to 8 Meg ohms. I would have expected in the 0- 200 ohms but have never measured this type of sender. Anyone got experience in them Cheers Si
On the positive terminal to the earthing terminal. Using ohms law the current would be micro amps..... I think it's faulty, strange as it rises and falls when I filled and emptied the tank with a hose pipe?
I'm sure now the values are suspect. I have ordered a new unit and I will test that when it comes. Parts cost keeps on rising!
