Found out a 10 year old multimeter was reading 3 ohms high on every test
I was chasing a weird ground fault on a King KX 155 nav radio last Tuesday and spent 4 hours swapping connectors. Finally grabbed a buddy's Fluke 87 and my readings were way off compared to his. Anyone else ever find out their test gear was the real problem after wasting a whole shift?

Dude, "reading 3 ohms high on every test" hit me right in the gut. I had a similar thing happen with an old Simpson 260 meter I'd been using for years. Was troubleshooting a flaky contactor on a chiller, spent a whole Saturday swapping relays and checking wire runs. Finally a buddy brought his meter over and my readings were all over the place compared to his. Turns out the internal battery in my meter was corroded and the range switch was starting to go. Felt like such a tool for not checking that first, but I bet we've all been there with gear we just assume is fine. It's always the simplest thing you overlook that costs you the most time.

Hang on, are we really acting like a blown fuse or a corroded battery is some kind of electrical tragedy? @emma_flores, you probably just needed to wiggle the leads a bit, right?

Borrowed a buddy's meter once and found out my "trusty" Fluke was reading 2 volts high on every DC range. Felt like I'd been working with a broken compass for a month. At least your battery was corroded, mine just had a loose fuse that I'd been bumping around for who knows how long.
