Quick question on the 671 E-Unit. Does the E-Unit normally function at a low voltage setting when using a ZW? When I place the transformer lever to the 3/4-Full Power Range the E-Unit energizes quick and the plunger is retracted up into the coil and essentially functions as it should. I am new to Lionel and figured the E-Unit operated in all voltage ranges. On the lower range it buzzes a little and the plunger moves a little. Sorry for the silly question.
