ZT-T 190 oil light

bsafly · 2nd March 2021, 14:37

Turned the ignition on theZT-T this morning and noticed the oil warning light was very dim, went out in it to do essential shopping.
When I started it at the shops to come home noticed the oil light didn't illuminate at all, checked when I got home, still doesn't light up even after a few minutes standing.
Is this most likely to be the oil pressure switch, or LED on the dash?
Where is the oil pressure switch located on a V6?
Once the engine cools down i will disconnect the wire and earth it out, should indicate whether it is switch or LED.

Just been out to the car and located the oil pressure switch, disconnected the connector and earthed the wire, turned the ignition on and the oil pressure warning light worked - must be the switch i thought.
Reconnected the connector and the warning light illuminated!
Started the engine - light went out. Turned off the engine, turned on the ignition and the warning light came on as normal
Checked several times and it's operating as expected.
I will have to assume a dirty connection at the switch was the cause, but I will monitor it just incase it was some other electrical gremlin.

Put some Vaseline on the connection.
