Bob,

I missed this post earlier and noted your comment Re. this corrected diagram in the other thread.

I'm hoping 4-5" from the case is close enough to tie into the ground wire for pin 1 input? As I mention in the other thread, for some reason the ground wire on this unit is massive, around 12-14AWG.

Exactly what parameter is being conditioned by
the AD626?

My apologies, I got your particular task
stirred in with another conversation on use
of the AD626. I recall that you're simply
wanting to put a small gain on the advance
signal from the Electroair ignition system.

I downloaded the Electroair experimental
installation manual which is very UNCLEAR
as to what all the ground connections are
. . . and what kind of current flows in each wire.

Given the dearth of clarity, here's my best
recommendation. Use Pin 14 of J1 as the
(-) input measurement point. And, of course,
you already know that Pin 21 is the (+)
input.

Sorry for what must have appeared to be
a rather obtuse posting . . . didn't realize
the struggle with poor data.

Bob,

I should have been a bit clearer myself on the ground wire off that unit since --you're gonna love this-- it's not on the diagram!

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!

Wade
