I am trying to replace the CHT probe on my primary triple instrument and the part number i was given by my A&P was 1514340. when i ordered this part, the suppliers gave me an updated part to replace it, 3080-00038 kit. the new probe has a room temp resistance of 5k ohms, the gague when tested with an adjustable resistance box reads correctly when 0-145 ohms is applied.
This is either the wrong probe or gauge. Can you direct me to the correct probe or gauge? see document for more information.
