Help!

Oil light has come on but levels and pressure fine. What is going on?! Doesn't go off when blip throttle.

Any one have any ideas?

If the pressure is good I would think you would be OK to carry on. Pressure warning switch and pressure gauge are separate sensors. Can’t remember if the warning light is short to chassis to come on or open to come on. If it is open to come on then probably the wire has come off or is broken. The sensor is difficult to see because it is behind the alternator. Actually having pressure is the most important thing.

Logic says its a duff pressure switch if the gauge is reading OK, but if it goes bang its not my fault!

I think from memory the oil light runs off of the coil?
are we talking about the red one at the top?

if levels are fine and you definately have good pressure then I don`t think you have a serious prblem

Engine should still be ok if you have pressure showing on the gauge, sounds like a fault with the electrical sender for the warning light, which is seperate to the sender for the gauge.

I tend to agree that it should be ok and that it is probably a simple fault.

recovery r enroute now cos I tried it a minute ago and there is a slight mechanical whine that I didn't hear the last time I had my head under the bonnet. It is kind of a whine that just doesn't sound right

thanks for your inputs and I'll keep you posted. At least the sun is shining and I didn't happen enroute to the growl!

IIRC 12v dash supply to bulb/led - single wire to pressure switch which is bolted to engine ground. Internally it makes to ground until pressure breaks the connection and the light goes off. If the switch fails it can be always on/off, if the cabling is grounded the light will always be on.

NO connection with the coil AFIK, except everything eventually traces back to the battery.
