Piper Meridian Oil temp issue

[gareth howat]

Hi everyone, Anyone on this forum owned or maintained a Piper Meridian with the Avidyne entegra package?
We are fault finding an issue with the oil temp indication, the temp is displayed but is around 10 deg C less than ambient indication (OAT) and begins to rise after start up but then the oil temp display blanks out at around 42 deg C, we have tried another probe and confirmed the wiring is fine, any further diagnosing assistance would be appreciated,

Get some stabilant 22 and put it on all the connections in the circuit. If you really have verified the wiring and transducer to be good there is a reasonable probability the issue is resistance in a connection. The stab22 Often will resolve that issue.
