I had the pressure switch to the Hobbs meter changed out as it was leaking and the Hobbs meter stopped working. Now the oil warning light comes on when the engine is running. Pressure and temp gauges so green, but it gave me a start when I first noticed it. I know that some switches are normally open and some are normally closed. I guess that I purchased a normally open when I needed a normally closed? Are there two pressure switches?

Can someone help me?
