Hi,
I have a Rotax 912 ULS. / Dyon Skyview Class SV-ADAHRS-200, SV-EMS-220, with 2 Dynon EGT K Type Thermocouples/Probes PN. 100405-001
Today, on start up my EGTs were working fine.
Taxied out to runup bay and Number 1 EGT readout went blank & I received an EGT warning.
As I prepared to return to hanger, the EGT came good.
Went for a fly. Engine running just fine.
About 30min into the flight , EGT No 1 went blank again. Also had very brief/flash readings above Max EGT.
Retuned to airfield.
In situ, visual/external of EGT's leads/connections all look normal/good. Connections nice & firm.
Check resistance /continuity with multimeter. Both EGT's have continuity. No 1 resistance significantly higher than No 2. Unable to do a full check as engine still hot.
Will return tomorrow to do a ADAHRS diagnostic download & test Probes with heat gun
Do I have a Probe or ADAHRS problem?
