Re: [Amateur-repairs] Test jigs for potentiometers, TO-220 devices?

 

Todd,

The idea here is to batch-test so that I don't have to get out the clip leads and other pieces every time I want to use one of these parts from the junk box.  After a few times of jury-rigging a test set, I'll have used up the time needed to build a jig.

At least that's my theory.

I have a bunch of old pots that need testing, as well as dozens (maybe hundreds) of LM-317 and 780x style voltage regulators.  


Jim,

Here's just a thought . . . don't test them at all until/unless you go to use one. 

For myself, I've got so much surplus stuff, and so little time to devote to projects, that I can take a few minutes (or less) to test something before it goes into a project. When I do, I rely on a few of those Chinese test modules from eBay, or just a DVM. It might be worthwhile to spend a little time putting together a simple test board for the regulators. It might make a niffy little Arduino project you could pull out when you need it.

73,

Todd
