Merry Fisher 805 Nanni 4,390TDI Glow Plug Light Operation.

[william51]

Could me assist me and tell me if this normal for start up from cold.   The Battery and Oil Pressure warning lights illuminate ok on the Nanni C3 panel but no such luck with the pre heater glow plug light, not even a flicker..  Emgine starts on the button and I have tested the glow plugs all working .    Is this because ambient temperature is around 15 degrees Celsius or should the light stay on as in diesel car for few seconds.
Appreciate any advice given.
