Oil Pressure Light question

 

Hello everyone,

Here is a question. If I turn the key on with my ej22 86 Westy I get a quick on flash on the oil pressure light. It does not blink...just a quick flash. This is from cold. All the other dash lights work as they should. To make this even more interesting every so often it does flash as it should. Seems to me to be a questionable sender. Would I get agreement on that? Now the question is....is the oil pressure sender under the alternator? I will start of course by checking that plug. However can anyone else suggest what else I should look at as well?

Thanks in advance,

Michael
 

Hi Michael,
The oil pressure switch is just under/behind the alternator/Power steering pump.

I suggest you just un-plug the connector from the switch and connect it directly to a good ground. This should keep your oil pressure LED ON all the time. If it doesn't it suggest there is something wrong in the wiring from that Oil Pressure connector to the instrument cluster. Try cleaning all the contacts in that circuit - starting with the Subaru engine connector.

Good luck,

Pull the wire off the Oil Pressure Switch. Run a new wire with a female connector to the switch back to the black box connector on the firewall. I had to do this on two conversions so far.

The one blink is because the LED is not grounding via the switch.....unless the Dynamic Oil Warning board is installed in the cluster, then I don't know what your find.

...IIRC, the Oil Switch wire in the black box is Blue/Black. If you ground that wire at the White round connector the LED should stay lit with ignition on.

Yet again Tom....you NAILED it. Did the idea below and gained a flash as it should. Next move....replace sender. Does the alternator need to come out of it or be moved out of the way to remove the sender or..... maybe I will have my 12 year old do it with his tiny hands. What would you suggest?

Thanks again,

Michael

Hi Mike,
I always remove the alternator - it doesn't take long and gives you much better access.
Good luck with it,
Tom
