[W126 Coupe] 500SEC engine/starter question

[Josh Allen]

Well, I never altered the neutral safety switch, so I hope it's still 
set properly...  I'll have to go check, but I never changed anything 
down there, other than disconnecting and reconnecting when R&Ring the 
engine/tranny.

Now that I've had some time to think, I'm leaning toward thinking that 
I've somehow gotten battery power applied to the starter control wire in 
the main vehicle harness, not the section that jumps from the fender to 
the starter.  When I unscrewed the rear terminal and pulled the starter 
solenoid wire out of the set, there was still continuity to B+ present 
on the other violet/white wires that it shares that terminal with.
