What is controlled by these switches? Are the
'mags' legacy magnetos or p-mags? What is the
largest anticipated current to be controlled
by any one switch?

Thank you Joe.
The OVM wiring makes perfect sense now in the schematic. I'm pretty sure that's
the way I wired it, but it's on my list of the next hangar visit.
I kind of get the reverse polarity protection, but I'd really appreciate a brief
description of what happens should the GPJ get a reverse polarity input.
Dennis, thanks for calling the battery symbol into question. It had never occurred
to me that there was a convention re which plate size was negative and which
was positive.
Googling images for "12v battery symbol", it turns out that the small plate is
negative and the large one positive, so my symbol on the schematic is correct
with the small plate connected to the ground bus. But I didn't know that.

The battery symbol thing actually carries over into the physical manufactur
e of the battery. The larger post on a conventional automotive battery is p
ositive the smaller post negative just like the schematic symbol.
Think of negative as less (smaller) positive as more. (larger)

If the ground power polarity is wrong, the lamp will not illuminate nor will
the ground power contactor coil be energized because the diode blocks current
in the reverse direction.
If the ground power polarity is correct when plugged in, current flows through
the lamp and the diode and 2 amp circuit breaker to ground and the lamp illuminates.
Then if the switch is closed, the contactor coil is energized by current
flowing from the ground power plug to the contactor, through the coil, and
switch, and diode, and 2 amp circuit breaker to ground.
Now that the contactor coil is energized, it will hold and stay energized even
if the ground power is unplugged. Current flows from the aircraft battery (unless
it is completely dead) through the already closed ground power contactor
contacts, through the coil and switch and diode and 2 amp circuit breaker to
ground. The ground power switch should be shut off whenever the ground power
is disconnected.

| Subject: | KX-125 to Garmin SL-30 Upgrade Mounting |
Dear Listers,
I've currently got a King KX125 nav/com in the RV-6. I was thinking of upgrading
to a Garmin SL-30. But, as luck would have it, the vertical heights are different.
The Garmin is about 2/3's the height of the KX-125. Does anyone know
of a sweet installation kit that I could use to mount the SL-30 in the same
hole that the KX-125 is currently in? Something that would look like it was suppose
to be that way and not a klugy deal?
Thanks!
Matt

Matt,
What's above and below the current KX-125? If it's blank plates, you can
take up some of the space with rubber U grommets. You can find various
styles at ACS. If it's other radios, I've used black rubber tubing.
Squeeze it in after the SL30 is mounted.
Of course... If you've got very much upgrading or rearranging going on,
having a whole new panel made is the clean solution. Having one
professionally made, powder coated and silk screened is under $1K. Not
too much compared to all the other stuff you put in the panel and it
makes the airplane look more finished than patched.

Depending on what is desired, or if the SL30 is already procured, the
new Garmin replacement for the SL30 is a little taller and has a few
more features/integration with their brand GPS units.

Good memory there Dave. I did replace the crimp and all seemed well
with the original installation.
However, during my problem determination and fell back on the good 'ol
swap the box solution. That is, I bought a new strobe unit to replace
the "Avi-Pak" unit from CreativAir. I picked up the "XPAK604X" unit
from Nova Electronics. It is a non-aviation unit but it mounts in the
same mount and looks like it is from the same manufacturer.
However, this unit keeps the switch out of the main power circuit. That
is, the XPAK604X has a power circuit that in the '10 can be run
directly from the rear mounted battery to the strobe power unit - a run
of less than 2 feet. Then the panel switch is wired on a separate
control circuit. Notably, the panel switch no longer is warm to the touch.
I've been running this for about a year and all is good.
Can't do it now but I can supply more information if needed.

I did some tests with our crimper. As long as it's used correctly, it
still makes good crimps. Whew!
I made some poor crimps on purpose, and they looked like the the one that
failed. But I really had to abuse it. Musta had a bad day.
Bill, I like the idea of having the switch as a control. The strobe pack
powered by the failed crimp is the certified Whelen version with regular
strobes and LED nav lights. Personally, I have an automotive Whelen version
in my plane. I haven't looked at it lately but I recall it has a blade
fuse in the case, as you mentioned only a few inches from the master relay,
and it switches to ground. But I don't think the switch is a control as
you described since it's the only ground in the system.
