This is one of my favorite videos from Eric O. at the SouthMainAuto channel.

It’s one of his shorter videos, a great example of how to avoid throwing parts at a problem. If you’re not familiar with Eric’s channel, let me just say that proper diagnosis is his middle name. A solid choice to add to your subscriptions, for sure.

BONUS THING: This video is where I got the idea for my recently-improved test lamp. But as much as I’d like to give Eric credit for the idea, apparently it was sent to him by a viewer. So whoever you are out there, thanks for that! This “scope-on-a-rope 2.0” is amazing.
