Battery charging - RED
The light illuminates as a bulb check when the starter
switch is turned to position 'II' and extinguishes as soon
as the engine is running. If it remains on, or illuminates whilst
driving, a fault with the battery charging system is indicated. Seek
qualified assistance urgently.
Check engine - AMBER
