To put the quote in context, here is the rest of it.

"...
His recommended solution is to put on-off switches for both the primary
and secondary injector pairs.  His logic is this allows one to disable
an injector pair if it is misbehaving, and at the same time prevent the
backward EC-2 power phenomenon mentioned above.  I am not a fan of this
solution - I wired my system with a single switch
primary-both-secondary.  I figure if I have injector problems, I don't
want to be flipping a pair of switches trying to find the right
setting.  There is comfort in knowing I need only flip a single switch
either up or down to disable which ever pair is not working.

So it's really just an issue of his preference for having one switch
instead of two.  Apparently he doesn't have a master switch for the bus
either or didn't turn it off.  Otherwise, the only time the back power
causes a problem is one of the reset modes for the EC2.

Interesting choice of words used -  "I'm not a fan of this (Tracy's)

 It raises the question in my mind that  with Tracy (the designer) saying
there is no problem, then  this search for a "solution" is for  What?
problem? One in the mind of someone with lack of understanding of what this
really means? or does someone have a  real reason for why this "sneak
circuit) should be considered a problem? Or is this "concern" being perhaps
artificially generated by someone who has anomisity toward Tracy and wishes
to raise unjustified concern about RWS products.  Ah, the possibilities are
too numerous for me to hazard a guess.

The "sneak" circuit is no problem if you wire the EC2 per Tracy's
guidelines - in my case, I must admit I did wire it a bit different - but,
that resulted with my EC2 now having two independent power sources - one
through the injectors and one through the EC2 normal power terminal.

 Not that I would ever normally attempt to power the EC2 only through the
injectors - but,it  is sort of nice in the unlikely event the line providing
power to the EC2 terminals 33 & 34 should loose power. Power through the
sneak circuit through the injectors would keep the engine running.  So - see
its not a problem, its a benefit.{:>)

Too much, gotta get to work
