Hey Ken, it sounds like the ground and the neutral are not tied together correctly back at your power source. Also, those solenoid coils are a very low resistance and can make strange readings if your power system is not correctly grounded. If a 110 volt transformer is your power source, then you must ground the neutral wire to it, but only at this point. Then you should get good readings from ground or neutral wire to hot wire. Let us know how this suggestion works for you, and if you have any additional questions, please don’t hesitate to ask us.
