Hi Bob,

Did you connect one side of the test light to ground and the other side
to the injector pin?  If that was the test, the light is providing
enough current flow to activate the injector.  If you connect one side
of the light to BAT and the other side to the injector pin (not the
power one), then the light will come on when the EC2 activates the
injector.  The series resistors act as current limiters for the low
impedance injectors.  I think you would see the light flash when the
injector is activated no matter which side of the resistor you're on,
but you would get the full 12V on the EC2 side.  That would only tell
you the signals were correct, not that the injector was actually
working.
