Well this is all a great OD education, so let me ask another question. 

Michael Salter said "If the accumulator was leaking badly enough to prevent the 
overdrive from engaging you would never see 390 p.s.i. if you are testing at 
the operating valve plug with the ball and spring in position".

My pressure testing rig is based on an old Del Border suggestion of connecting 
the pressure gauge through a hole in a spare operating valve plug. I can not 
recall whether I tested with the ball and spring in position or not. 

I suspect that they were both out. Would this invalidate my results?
