Subject: EC2 Sneak Circuit Gone!

While at Tracy Crook's before Sun & Fun, Tracy was kind enough to put the snubbers in my EC2.  I have one of the older EC2s which has a LED  light in the Program button.  I  early on discovered the "sneak circuit" which would provide power to the EC2 through the injector switches even if the main EC2 power switch was turned off.
 
Well, yesterday, I went out to the aircraft to check my gadget's interface to the EC2 and noticed that when I turned on the injectors, the LED on the tip of my Program button no longer lit up.  I tried the main power switch and the LED did light up -so the LED was OK.  But, the injector switches would no longer causes it to light up.
 
So I called Tracy to check and insure myself that all was OK and he agreed that a "side effect" of installing the snubbers was that the "sneak circuit" path no longer provided power to the EC2 innards. So I thought I would mention it to the list.
