Hi Bob,

I can't think of any good reasons to hear anything from the connector,
and only a couple of not so good ones.  A current high enough to make a
spark, or some mechanical movement inside the connector.  The output of
the EC2 should either be at ground or a fairly high resistance so no
high current flow from there to ground. The diodes should block flow to
another injector that was still connected, so no current flow there.
I don't think putting a probe in the connector should move anything
enough to make a clicking noise.  I don't know what it could be. I'll be looking forward to a report after you get the EC2 back.

I had the wires disconnected from the injector, so the click was from  the connector itself. Had power on one wire and no power at any time on the  other. not even a flash when the button was pushed. One the store button is  pushed, should there be power to the injector for the duration the button is  held down, or will it just flash the injector with power. If so my light might  not have time to light up if its a milisecond or so.
