OK, here's a stupid  question (and I'm probably a stupid person anyway, so no need to argue about  stupid questions... ),

  

 I'm re-wiring my  RV-8 with a Z-13/20 system. Using the B&C battery contactor, I will have to  splice on approximately 1.5" of 2 guage cable unless I install it upside down  (or move it to another location, not something I want to  do...)

  

 Question 1: What are  the issues, if any of a contactor installed upside down (I have read the stuff  in the Connection about the aerobatic dude who killed his starter allegedly from  to many G's on the starter contactor...  I kinda doubt the G's I'll pull in  my -8 will be comparable...)?

  

 Question 2:  If  I simply reversed the diode and switched the wire from the main contact to the  other side, have I essentially "reversed" the contactor? (not sure that made any  sense. Look at the side of a B&C contactor and make all the wires on it a  mirror image...)

  

 Thanks for any  advice,

  

 John

    What you should have deduced from reading about g-loading

    was that the whole idea is a myth. The 4-terminal contactors

    sold by B&C are mirror image . . . you may reverse the fat

    terminal functionality and/or small terminal functionality

    at will . . . just make sure your diode polarity is correct

    for what ever configuration you choose to use.
