FWIW, I too took the fuse direction in my RV10. However I do have 4 CBs - 2 as called for by my B&C regulators, 1 for the AP as an emergency disconnect and 1 for my flaps (unnecessary). I have 30+ fuses and never looked back.

Art, what will you be soldering? I think it is the consensus of this list that for most connectors it's better to just crimp, not solder.

Art,
You have just gone and opened up a whole new can of worms considering that most, if not all, of the advice I have seen on this forum recommends CRIMPING over soldering in almost all cases.

Crimping is faster, and if using subD connectors, allows mods and correcting mistakes in wiring. But it's a lot more expensive. If you have the skills to solder, it will work just as well as crimping. A good solder joint is better than a bad crimp, and bad crimps can happen, just like soldering. And soldered in-line splices are a lot more compact than a butt splice.

Exactly. We spend quite a bit of time in my
weekend seminars talking about wire joining
integrity. From a purely functional perspective,
crimping and soldering are interchangeable
Either one done correctly is a stand-alone
process . . . in years past, some builders
confessed to having soldering their terminals
after crimping!
I own perhaps a dozen different soldering
tools . . . and a couple dozen crimp tools
with no inhibitions to the use of either
depending more on conveniences than on
the relative 'goodness' of the outcome.
I needed to built a custom inclosure for
a project a couple days ago. 10 minutes
at the shear and 20 minutes on with the
soldering iron produced an exactly right
size box from 1/16" copper-clad.
I could not have 'crimped' those sheets
together. Its useful to be competent and
comfortable with both technologies . . .
it can only broaden your options.

I don't know that this is true. Certainly, crimping
is faster, lower risk for damage to some components
and takes less skill to get repeatable joints. At
the same time, not everyone is going to invest in
some of the more expensive crimp tools just to build
one airplane.
One set of joints I ALWAYS solder it to put terminals
on fat wires
http://tinyurl.com/gm8lqxo
I seldom need to do this and just never found it
attractive to go buy the hydraulic tool and matching
die sets. I bought a hydraulic tool from Harbor
Freight a few years ago . . . worked good . . .
was a fine "masher". Problem was that the dies
provided did not always produce the void-free/
gas-tight joint on the combinations of wires and
terminals in my inventory. Sold the hydraulic
tool on eBay.

Speaking of crimping and soldering, I have been trying to find some 3 row, 20 pin d-sub connectors for my
Link trainer for three years. Does anyone on this list know where I can find some of these ?

Google "HD-20 D-sub" and take your pick from the many electronics suppliers that have them (digikey, mouser, element14, rs-electronics etc)
I'm hoping this is the 20 pin d-sub connector you're looking for.

20 pin? Wow . . . that's a new one on me.
The only three-row connector I've actually
seen in the smaller shell sizes is the 15
pin VGA video connector that was common to
the computer industry for years. I've read
about some 19 and 22 pin connectors seen
on Mac and Commodore computers . . . probably
specials.
Are all 20 pins used? Could you punch out
the hole and change it to a 25 pin from
the more garden variety options?

Maybe you could use the services of someone with a 3d printer. Is the housing itself the only difference, or does it use different pins too?

Bob,
There are a few things I could do but, wow, what a headache.
The link trainer has two female plug sockets mounted within a plate on the side of the machine.
To start changing connectors I would have to make a new mounting plate and desolder 40 22 ga. wires
then solder them back into the new connectors. I would have to do the same to the 20 wires that are part
of the flight recorder.
Yes, these are pretty old connectors. They were used on the trainer when they were built in 72.

Mmmm . . . making a new plate to mount larger
connectors is pretty easy if you have the
punches for d-sub holes. I do have those.
I could, in fact, make you any new flat-plate(s)
properly punched, in a few minutes.
I wouldn't use solder connectors for so many
wires. I've probably got what you need in
crimped housings and pins to do the job.
Got a tool I could loan you too.

Larry,
Would the pins in the existing connectors fit in a new 26 pin or 25 pin body. If they would that would eliminate the soldering or crimping. Just move the pins with the wires attached to the new body. Just a thought and probably not a very good one at that.
