Yes, there is actually a separate ground wire that is not depicted on that diagram, and again, for some reason it's quite robust (~12-14AWG). So I measured the distance from the case that I tied into that big ground wire with my 22AWG lead for the AD626 (-) input at 4.5 inches. Sorry for the confusion and thanks for the help!

That may be the ground return for the 9A coil charging current cited in the installation manual. For your purposes, tying AD626(-) input to the same airframe ground as this wire may not be a problem but after you've got the system up and running, you may observe behaviors that prompt further inquiry and perhaps relocation of the instrumentation ground. Given the short length, you're probably going to be okay.

Here's one that works on 12V, & you get 2 spare devices in the package: http://www.ti.com/lit/ds/symlink/cd4082b.pdf --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 7 _____________________________________ Time: 12:40:19 PM PST US From: Ken Ryan Subject: AeroElectric-List: capacitor durability So yesterday I received my shiny new 33000 micro farad capacitor, for use with my Silent Hektik regulator. Within five minutes, I had managed to drop it from a height of three feet onto my hardwood floor. The floor is fine, but I wonder about the capacitor. How likely is it that it was damaged?
