RE: Dynon Oil Temp erratic
Phase one continues for my RV7A......A few squacks to overcome....none too serious.
The Dynon EMS D-120 Oil Temp has been real erratic. Swings plus or minus 20 degrees around 200 degrees F. All CHTs around 350.....![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
It appears that I may have a ground problem. The oil temp sender body is grounded to the engine case and according to Dynon that if there isn't some "magical / perfect" (my terms) ground betwen the case and the battery the instrument will be erratic!!!!! On the Dynon forum one individual (with the same problem) used a GRTs oil temp probe with it's own ground wire and sender wire in place of the Dynon oil temp sender. He said is oil temp was rock solid using the GRTs probe.
Have any of you Dynon guru's had this problem and if so how did you fix it ( without rewireing your plane ) and did any of you use the GRTs probe????
Considering I am breaking in a new Titan ECi IOX-360 Oil Temp is important to watch as a rock solid # indicator.
