CORRECTIO
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!

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.

Bob,
I'll take note of that and watch it during future testing.
Thanks again!

| Subject: | Need a device to send 12volts when all 3 green lights |
are light
Below is the landing gear circuit, I need a device or build one that can u
se the 12volts coming from the gear down and locked switches and only send
12 volts to another device[for testing a led] IF ALL 3 lights (gear down an
d locked)
I thought use 3 NPN transistors in series but it seems on my test, if I sup
ply 12 volts to the base of the npn it still lights the led (leak though ?)
with no voltage on anything else
I am using figure two of these examples

IDEAS ?

Look here:

Note that a quad input AND gate might be easier to find, and you can use
it as a 3 input by tying the 4th input high.

Here's one that works on 12V, & you get 2 spare devices in the package:

| Subject: | 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? How
would such damage show up?

Can you just hook all the down-lock switches in series?

Extremely unlikely to be damaged Ken, provided of course tthat the
terminals weren't broken off.

Then I would lose each gear indication. This is for an audio alert device
input if the gear is not down and locked (all 3)
