I don't understand what you mean by "the connector output lead for pin #36 
had 2 wires coming out of it, even though the input side only had 1 wire." 
 
What is pin #36?  How can a connector have an input and an output?  Sorry, 
I 
guess I'm just not picking up on your nomenclature here.

Are you saying that you connected the Alltrax field outputs to the same 
terminal?  If so, that would sort of explain why four of them failed.  A 
short circuit on the field output is generally fatal.  

Or are you saying that one of the Alltrax's field connections went 
nowhere?  
I think I recall that Alltrax controllers also don't like open field 
connections so that could cause it some consternation too.
