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.

So, I've always just soldered & then heat shrunk to insulate. But, while prowling an Asian shopping site, I stumbled upon these: https://www.tomtop.com/p-e12176.html?rc_token=null I'm sorely tempted to roll $20 worth if dice to see if they're any good.

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. -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=497884#497884 ________________________________ Message 4 _____________________________________ Time: 05:06:17 PM PST US Subject: Re: AeroElectric-List: Re: inexpensive (or possibly just cheap) solder sleeves From: Charlie England On 8/20/2020 6:33 PM, user9253 wrote: > > Don't do it Charlie.

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.

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.

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.
