A requirement seldom if ever explored
in OBAM aviation is a demonstration of
suitability to task. I.e. will the machine
deliver design goal ratings to the system
under worst case conditions?
When seeking to validate a new install
a legacy 'stress' test calls for loading
the alternator to design limits (may not
be nameplate limits . . . some alternators
are purposely 'de rated'), climb the
airplane as best angle, monitor critical
temperatures in alternator (usually diodes
and one stator winding) until stabilized.
Adjust for standard hot-day and show that
the installation meets design goals without
overheating.
It's not possible to load an installed
alternator to design limits using ship's
accessories . . . we add current draw with an
adjustable load bank that lets us fully
challenge the alternator.
This is a load bank recently used to
validate a new STC on an alternator
installation.
This seems like an extreme measure given
that loading a qualified installation
to worst case for more than mere minutes
is practically impossible. But the test
proves that your properly functioning
alternator is meeting design goals.

Solder sleeves are cool tools, but I'm way too cheap to pay almost a dollar
a joint. So, I've always just soldered & then heat shrunk to insulate.
But, while prowling an Asian shopping site, I stumbled upon these:

I'm sorely tempted to roll $20 worth if dice to see if they're any good.

Don't do it Charlie. I do NOT think that they are solder sleeves. I get the
impression that they are crimp connectors. Nowhere does it mention solder.
Heat is used to shrink the tubing.

Well, duhhh...
The first item I looked at really was a solder sleeve set, but the set
included a bunch of regular shrink tube segments. I carelessly clicked
on one of the other products displayed on the page (this one), without
looking carefully at it and thinking all the displayed items were solder
sleeves.
Thanks for the good catch; I'll try to go back and find the actual
solder sleeves.

I think this was the 1st one I saw. Still not a bad price if you ignore
the standard heat shrink; 100 pcs solder sleeve for $19.00. I'll dive
into their listings & try to find an assortment that really does contain
solder sleeves and doesn't contain generic heat shrink.

Charlie...et al.
I purchased a similar looking box from Amazon and was disappointed. The
shrink sleeves are extremely thin .008-.012 in wall. the solder sleeves
were also very thin wall. If using multi strand with fine strands there is
insufficient solder to fully wet out the strands.
