Right you are, Bob. All the parts are from B&C, so that wasn't the problem.
I just don't think I was getting those suckers all the way in there. They
DO seem nice and snug now. This still leaves me with the question of
whether some kind of strain relief needs to be incorporated, but these
connectors aren't going to be yanked around - they should end up tied down
or otherwise fixed in position except for maintenance, etc. operations.
Your thoughts?

--> AeroElectric-List message posted by: Don Boardman <dboardm3@twcny.rr.com>
Hi Bob and All,
Quick question. Is there any concern about mounting a battery contactor with
the coil tube in the horizontal position? Given the pounding that our
seaplane will take on the water I wondered if there was any problem with the
coil holding the contact bar in a horizontal position verses pulling it down
while in a vertical position.
Thanks,
Don B.

I did what Bob suggests to make it convenient and maintenance friendly. I
put it right in the lower part of my instrument sub-panel on which meets the
suggestions of the voltage regulator designer too. I can see it when the
tip up is open and I can adjust the voltage if need be. And annually I can
easily see to trip the #2 and 6 terminals to be sure the LR3 still works.

| Subject: | KX 145 squelch problem |
--> AeroElectric-List message posted by: f1rocket@telus.net
Hi listers.
I have an old KX145 that only has a few hours on it (plane was in storage for
20+ years). During retesting of the plane I discovered a problem with the
radio.
If I turn the squelch down so I don't hear any static, I don't receive anyone
(right at the very left end of the dial). When I turn it up and am willing to
listen to the annoying static (so much for the noise cancelling headphones)
everyone comes through nice and clear.
Any ideas where I should start looking here? Anyone have schematics for this
radio?
Thanks,
Jeff
