--> AeroElectric-List message posted by: "Bryan Flood" <bryanflood@hotmail.com>
Could anyone share a diagram for wiring two trim switches together for a
single RC Allen servo (Pilot / Co-Pilot)? To make things fun, I was also
hoping to use a dual switch "fail safe" system like the big boys to prevent
a run away trim in case of a switch failure.
any one up for that challange?
Thanks,
Bryan

I have a King CDI localizer head, I think it may be a KI-201 It was the
head for a kx 170a, replaced the radio with a michel MX170 , which seems to
be a pretty good radio, despite a few idiosyncracies. Last week I was
shooting an ILS (this is my back up head, the main GS head seems to be
working, ) and I noticed that the Localizer needle was not behaving like
the one on Nav1 KX170b, with GS. It just stays centered, and I don't fly
that good an approach!
I have tried these steps to trouble shoot.
1. disconnected the head, and cleaned the contacts with Caig De-oxit
2 Removed the radio, and cleaned the tray connectors with De-oxit as well.
3I took the kx 170 b and the MX 170 units out, and switched them. The
Michel seems to drive the Nav 1 head just fine, the KX 170b will not
affect the localizer needle whatsoever on the #2 CDI, so I am assuming the
radios are functional, and the CDI is busted.
Both radios will tune and identify the ILS frequency, in either position of
the trays.
The reason I bought the Michel, is that it fits right into a King
tray. This saved much Moola at the avionics shop!
It seems to me the localizer CDI head is pooched, It does not show a "to"
flag.
When you turn on the radio that is hooked to it (either the kX or the mx)
the needle jumps to the left a couple of dots, then returns to
center. Wiggling the tray or the head connector seems to have no effect.
Can anyone suggest the next thing to do? take it out and send it to a shop?
I really can't see putting a lot of cash into a head that is vintage '72
low end CDI head. I think a CDI is a bunch of money, and I use my Garmin
295 for most of the heavy duty navigation anyway.
This is in my Super Viking, but I'm not opposed to working on it
myself..too numb to be scared I guess!
Thanks, David Leonard

If the 2 heads are plug-compatible, you could swap the heads in the
panel to be sure the wiring between the radio tray & head connector is
ok. Assuming the known-good head responds properly in the 'bad'
position, then it's probably time for repair/replace.
