David,
Its normal for the program
select button to glow when power is applied to the EC2. I guess "Green"
might have been a more suitable color for a normal condition rather than "red",
but nothing to be alarmed about.
Yes, I first discovered that the
EC2 had a "sneak" circuit that would provide power through the injectors.
Tracy assumed that most people will kill power to the injectors and EC2 both by
turning off the master switch as he does. However, on my system the master
switch does not turn off anything critical such as the EC2 (wouldn't want to
bump it with my knee {:>)). So I wire up a separate switch for the EC2
CPU power, needless to say, it did NOT turn off the EC2 because of the "sneak"
circuit providing power from the injectors. Fortunately I had the two
injector switches that Tracy recommends and I turn off the engine by turning off
the injectors.
So not to worry about the
light.

Subject: [FlyRotary] LED on EC2 and Power
from injectors
When I power up my
EC2 the program select button glows red. I am hoping that this is normal
– although green would have been a more re-assuring color. The
interesting thing is that when I supply power to the main buss (but not the
EC2) the LED also glows red. Is this normal? The juice is getting
to the EC2 via the injectors (which are powered by the main buss). If I
unplug the injectors the LED goes out. Seems strange, but I’m hoping
everything is OK and hope I don’t have to start re-wiring.
