How would one go about safely testing a wound component such as a recently home wrapped trigger/power coil.? Answered

In general, I'd like to know how to safely test all wound components to verify that they are working properly. With emphasis on the safely part.

To really test it, you need a signal generator, with a reasonably good output driver. Ideally you need an oscilloscope. Drive the primary from your generator and measure the output. If you have a shorted turn, you will see a greatly diminished output, which you won't see with a simple multimeter test. You can cross check your tappings, make sure you have the start and end right etc. Of course, ultimately you need to run it at the design frequency, but this makes a very simple basic test, if the generator is reasonably close to the operating frequency.

A simple multimeter should be able to tell you that the wire of a coil has no breaks, just by checking the conductivity or resistance.

So just to clarify, no breaks would show up as ~0 - 3.6 ohm's? While I get a measurable resistance its showing up in the range of ~ 1200k ohm's on my coil. The coils specs ~ 380 windings around a 1" diameter core. I know there's a certain amount of internal resistance from copper but I wasn't expecting that much, I'm wondering if I might have a break. The coil is bifilar wrapped in parallel with 22guage and 26 guage wire.
