Our not-for-profit Mooney flying club is upgrading our 1967 M20F to a CGR-30P total instrument. As such we are selling the below items to help off-set some of the upgrade cost. Each item comes with a photocopy of the logbook entry that provides all of the below information and states that the equipment was functional upon removal. FSDO says that's all you need to reinstall in a certified aircraft. Photos and prices (or best offer) are listed on our website at http://www.monticellofc.org/aircraft/For_Sale.html . We are waiting until the winter to add a new fuel level gauge which will allow us to sell all of the cluster gauges.

The ones at the bottom are still available. For folks having oil temp probe problems, I highly recommend opening up the Amphenol connector on top of the probe, looking for loose wires, and re-soldering them. That happened to our old one, thus why the connector was newer than the probe. With all that engine vibration, that is the most likely culprit for no or intermittent oil temps. Another trick is to put wrist locks in the lines about an inch from the probe. That way you can open up the circuit, test continuity, and reconnect them.

Hi all, As winter is settling down, I have noticed that my engine oil temperature in cruise is getting a bit low... I would like to check with you what kind of readings you get from you aircraft. MP: 23' RPM: 2300' Altitude: 2500' OAT: 48°F AeroShell W100Plus Oil Temp: steady 166°F Oil Press: In the green band but rather low How does that sound ? Cheers, Philippe 1980 M20J

I have a problem with the oil temp and CHT gauges. Oil temp sometimes works, sometimes doesn't. When I turn power on, both gauge needles dive to the left. When I disconnect the sender for the oil temp, it does the same thing. When I ground the sending units lead (off of the sending unit), it deflects all the way to the right. Cyl. head gauge does the same thing but when hooked up, it's dead all the time. Both the sending units show resistance. Whats up and what to check next?
