Oil Temp

[N661DJ]

Had a recent situation where I noticed my oil temp. seemed to be stuck at 150*F, (Superior 0-360) RV8A. Contacted Dynon and was told to check engine grounding, no change, Finally changed the Oil temp probe PN 100409-001 now I am seeing temps where they should be 190*F to 200*F range. Strange that the defective probe would work well until it hit 150* and then remain there, never changing even 1*

I am having the same problem with my dynon oil probe, oil temp only read max 150 F after 10 hour of Flight, I checked with a second temp probe and second one reade 185 F, just where it should be.

For what it's worth, if it is a grounding problem with the Dynon units you will more likely see HIGH temps rather than low. Too, if you turn off the alternator you will see the value change immediately - that is the biggest clue to ground problems.

I have checked everything and I have tested the oil probe temp versus resistance from a chart sent by dynon and the problem is oil probe. So I need a new one.
