Having just replaced a ball valve on the engine sea water skin fitting due to what has been described as anodic corrosion, I have just stuck a multimeter between the skin fitting/ ball valve and the engine(-). To my suprise it shows a PD of 0.75V. Is this normal or do I have a problem ?
This reading was with no shore power connected and battery masters off. Connection shore power and batteries did not change the reading.
Help!
