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

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.

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 On 09/09/2020 21:07, 'robert greig' via Quantum Owners Group wrote: 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.
