Hello. Quick question. 

Oil pressure switch on the Xtreme! 
Mine is showing max when engine is running. It's not a stock Ford one. Two wires with push on connectos. 
I've seen on ebay simular ones. 80 psi or 100 psi. The gauge in the car is 90 psi max. 
Do I get the 100 psi? 

Thanks in advance. 

Robert.

There is no real standard, the sender needs to match the gauge.
You might need to take the gauge out and see if it has a make on it.

Could it be a wiring issue? What happens if you remove one of the connections from the sender? Try removing each one at a time.

I'm assuming it goes straight to max when you turn the ignition on, even before starting the engine?

Regards,
Steve

I had a couple of Green gauges oil pressure senders fail on my 2+2
In both cases the wire broke inside and the gauge went to max.
 
One connection is probably a pressure switch for the warning light and the other is the pressure sender for the gauge.

So I've tried 

First clean all contacts.   No change!
Take one wire plug off.    No change!
Take the other wire off.   No Change!
swop the wires round.   No change.

and yes if you turn on the ignition the gauge does go to max.

I was confused to start with, now I"ve ordered a replacement So hope that fixes this.

Many thanks for the help.

Regards Robert

Hi Robert, If as Jim says,one wire is for the indicator lamp and the other for the gauge, it could be a wiring fault with the “gauge” wire shorting to earth. Does the indication lamp come on and then go out with the engine running? If you disconnect the wires from the switch, does the gauge go to full scale or not move. If it still goes to full scale, a wiring fault is indicated. If not then the switch is internally shorted.

Regards

Ken

Aftermarket oil pressure gauges are often inverted compared to the petrol and temperature gauges on the Quantums.
These oil pressure gauges will go to max if they aren’t connected to the sender, or as i suspect the sender has gone open circuit.
Try earthing both the wires (one at a time), one will make the light come on, the other make the pressure gauge go to min.

Sorry Gents, I just caused confusion. I have not come across the inverted type.

Many thanks Jim, ken.

I will ask my dad to check earthing the wires one at a time.

I have a healthy respect NO... fear of wiring!  
As some of you know in the past I have had bad experiences with wiring ie / fire/ and shock. 

   
Many thanks.
Robert
