never tested the voltage until i hook everything up how it should have been,
either the black wire in the disconnect worked loose after yrs or it was never hooked up. he said he has always had problems with the box and the fuses.
it is a 240v heater and is working correctly now.
he said the black wire in the disconnect has never been hooked up so the white wire must have been overloaded and burnt i don't know. I know its working now and told him his electrical system needs some attention and he should get some one to look at it new wires and service. everything is old style wires and screw in fuses.
