Go to http://www.aeroelectric.com/Installation_Data they have the pinouts
You can check the continuity of the wires yourself. It will be a lot easire
if you can borrow a couple of pins to connect your meter with. Of course
the easiest way to troubleshoot is to swap.

We've got a dead glideslope needle on our #1 indicator. (KI-209 driven by
a
KX155 12v) GS flag works, needle stays centered.

I dug through our log books and noticed that this also happened in 2002
and
was repaired by "repair to aircraft wiring". I contacted the avionics
shop
that did the work and they looked up the repair order. They repeated that
the GS needle was inop and the unit bench tested good and that a wiring
repair was done on the aircraft.

I've haven't seen the back side of a 209 or a KX155. The avionics tech
that
previously repaired it says " it could be any or all of the 4 wires that
connect the +/- GS flag or the needle"

Can someone explain the wiring?

Thanks,
Jim Burns
