rear engine oil temp guage

[SkyKing]

Rick,

Before you rummage around in the rear engine compartment, you just might want to pull the right-side avionics hatch off and take a peek at the connector on the back side of the gauges to make sure that it's completely snug and connected...sometimes they have a tendency to come loose from vibration. Also, if you've had water leaks you could have built-up corrosion on the connector plug that finally rendered the connection nil.
