Thanks Bob, I didn't get that part. (or it was a different
message?) The part I got was asking for a diode fix to prevent the
problem (message didn't specify what that was). Paul then suggested a
diode in series with the driver which would in-fact prevent the injector
current from powering the EC2 but it also prevented the injector from firing
as well.
A triple pole double throw, center off switch might accomplish
the single switch goal if wired correctly. I have no problem with that
but don't see how it is related to the 'diode fix'.

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.
