I think that the way to check would be to disconnect the 'E' terminal wire from the cutout (the voltage coil is wired between the 'D' terminal internally and the 'E' terminal). Turn on the ignition and check between the 'E' terminal and the earth wire you have just disconnected and see if you have a voltage. You should have none at all. If you have a voltage, and it may be quite small, as there is a 30 ohm resistor in the warning lamp, then you have a short.
