We all see the light show when the key is turned on but is the Oil Pressure light On before you press the start button?
The manual page 32 seems to indicate it should be
Caution
"If the oil pressure warning light remains On after the start etc etc" I interpret this as the light goes out after starting
-
my Griso will does the light show when the key is turned to ON
the oil pressure warning light will goes off immediately after the light show/before the start button is hit
I believe the low oil pressure light is not hard-wired to the oil pressure switch like it used to be, the dash and the logic gets in between the switch and the bulb :rolleyes:
-
The oil pressure sensor is normally closed. Oil pressure while the engine is running keeps it open. The dash startup test checks it's closed. If it was open before the engine is running, you will get a SERVICE warning. If it stays closed after the engine is running, you will get a SERVICE warning, and the light should come one. The dash has smarts to know this, and it's state is tested at switch-on.
As Phang says, it's not a dumb light. The dash controls it.

same for the low fuel light of my Griso. If I remember correctly, it doesn't flicker when the fuel is sloshing near the tripping level.
there must be some logic in the dash to read a constant state of the switch during a fixed period of time before the dash turn on the low fuel light and trigger the countdown.
