[ercoupe-tech] Engine Ground

[hatfielddennis]

I read somewhere that the engine in my 1946 415 C (N2738H;#3363) should 
have a wire ground from the engine to somewhere on the engine mount. 
Since my engine does not have a ground like this, could someone please 
advise me if this is necessary and, if so, where the ground should go?
I have no obvious engine problems and no abnormal radio noise so I just 
assumed all the existing wires and cables provided the necessary 
electrical ground.  Thanks, Dennis
