Hi guys am a first time poster so be gentle .
I have an induced voltage of 70v on the faceplate of a control unit on an extract fan I am working on. I have taken the plate off and there is an earth cable from the plate going on to the circuit board on back of plate. But there is no earth from the terminal on the circuit board going back to the power box. Is this the reason I am getting induced voltage??
