When i got on my boat today i noticed that the Battery voltage meter on the Bavaria switch panel was showing 00.0 volts, yet when i pressed the buttons for either battery 1 or 2 the full voltage of each battery was shown, but upon releasing the buttons the voltage display returned to 00.0 volts. But to the best of my knowledge the display used to be blank like the meter for the water tank capacity. Can anybody advise a likely cause.
