I can’t fault them, they’re nearing 70 years old, and that’s a big ask from diodes that old! Still, we know for a fact that we have at least two bad diodes, and I suspect we may have dozens more. Which means, it’s time to test diodes. But when the machine has more than 3,000 diodes lurking inside of it, how do you test that many without losing your mind? Well, turns out, Bendix made a pretty awesome little tester to do just that!
