Oil light

[zidmie]

Hi all,
I recently had a little fear, when my oil light appeared. I checked the oil pressure, it was OK, then I checked the level, OK too. So I guess I should change the switch, then see if the light goes off.
It's an orange oil light, inside the speedo. My question is : is it a level warning, or a pressure warning? On "normal" cars, I would think that :
- an orange oil light means level is too low
- a red oil light means the pressure is too low
Is is the same on the Cerb?
I didn't find an oil level sensor on Racetech parts, only a pressure switch.

Thanks for the help!

It's a pressure sensor which reads off an oil gallery in the middle of the V, there isn't an oil level sensor.

Thanks,

Does it mean that I could have a good pressure in the pump, and a low pressure in the V, due to any big failure..?

Not really, the switch is right next to othe gauge take off, what does the gauge read, oil light switches break quite often.

Great news
The pressure reads about 60 at idle cold, about 30 at idle hot, +/-10.
I'll get the switch by the end of the week.

By the way I tried the car on a little track last weekend, it's great!!!!!!! Awesome brakes, no understeering, easy to control when over-accelerating in 1st/2nd gear...

It has been known for the oil light and battery light to be crossed over on some cars - it is worth checking whether the battery is charging. If not, the big fuse is your first port of call (in a little black box at the back of the engine assuming it's a V8).

Thanks for this info, TVR's reputation for electricity is real
In my car, the lights are at the right place, I already tried the battery light when I lost my alternator belt

New pressure switch it is, then

Spot on then, nothing wrong with these numbers at all.

Hi all,
I received the oil switch. Strangely, it is not the same I had before : instead of a 1/2" screw, I have a 17/32" (or 13.5mm?) screw.
Anyone knows where to find this?
Thanks

I forgot to close this thread some time ago... Indeed it was an oil pressure switch problem!
Thanks to all for brilliant advice as always
