I'll take a stab. Mounting "cap down" means that gravity (and a bit of 

engine vibration) will separate the main current contacts after the coil 

is de-energized should the internal compression spring fail. Mounting the 

other way would have the contacts potentially closing due gravity if the 

spring failed with  potential for all sorts of unhappy results.


	


   Okay, gravity is a player here (my earlier post spoke of

   g-forces which should have been qualified further to

   aerodynamic g-forces). Suppose we hypothesize that the

   spring is not going to fail. Now how does orientation

   affect operation?

Well, "cap down" means that gravity (in the usual aerodynamic sense of 

positive G maneuvering loads) will assist the internal spring in 

separating the high current contacts when the coil energizing current is 

removed. This would help in opening sticking contacts due to dirt, 

deteriorated contact surfaces, and the like.

Mr. Nuckolls,



	I am disappointed and saddened to see you engaging in the "I've got a

secret" style of information dissemination.



	If it is in the archive, please say so.



	If you have the answer, please give it.



Cordially,

Raymond Julian
