An old lead tech back in 2012 told me to stop chasing gremlins with a multimeter first

So do you actually think it's better to just blindly swap parts until the problem goes away? Because from where I'm standing, that "old lead tech" sounds like he was either super experienced or just lazy as hell. I've seen guys who've been in the trade forever that can literally hear a weird noise and know exactly which relay is clicking wrong, and they don't need no meter to prove it to themselves. But for the rest of us normal folks, a multimeter is the only way to actually confirm you fixed the root cause instead of just masking the gremlin with a new part that'll fail again in six months. What was the specific problem he was talking about when he told you that?

Wait, was this the same old guy who told my buddy about a condenser fan that would only act up when it rained? Anyway @kevin_murray88, my buddy's lead tech told him to just swap the start capacitor in a blower motor instead of chasing voltage drops. He was skeptical but did it. Fixed the issue. Sometimes those guys just know.
