Cluster Warning Lights
Hi all, my 75 911 2.7 has 2x warning lights on the dial which houses the oil pressure gauge & oil temp(temp on left, pressure on right)-from memory, i'm at work- and the 2x lights are centre.
The bottom one i think is alternator/charge & the top one is, i'm guessing oil pressure warning light?? This top one is very important to me as ive only just got the car running and most gauges arent working! Esp the oil pressure gauge! I dont want to destroy my engine because of lack of oil pressure! Help please. |

There are 3, in a row on the older cars.
The very top (red) one is not used on manual transmission cars; it was the Sportomatic oil temperature warning. The green one in the middle marked "OEL" is oil pressure warning light, aka "the idiot light". The red one at the bottom one is alternator/charge warning light. Check pressure with a mechanical gauge. The idiot light switch triggers at a really low pressure (5 psi, I think?); it's only there so you can check it goes out when you start the motor - and switch off if it doesn't.

Ok great thanks that clears it up.
The green oil light goes off after cranking the car for about 5-6 secs(with h/t lead disc) so yes it would be quite a low pressure warning. |
