I was flying at normal cruise and noticed my oil pressure was a over the 90 psi limit. Oil temp normal. Reduced throttle and no real change to pressure.
Landed and noticed oil pressure gauge indicated normal reading again. Pulled the cowl and noticed that there appears to be a ground wire clamped to the external part of the sender and it looks a little scruffy.
Searched forums here and it sounds like a bad ground on a single wire sender may be the cause of a false high reading.
So my plan is to clean the wire up and the external portion of the sender where clamped and test to see if it reads normally again and if not replace the sender. Does this sound reasonable?
