Spent 4 hours cleaning a shutter that just needed the battery checked

Customer brought in a Canon that wouldn't fire. I disassembled the whole mirror box, cleaned every contact, put it all back together. Still dead. Took me 45 minutes to notice the battery door was cracked and the contacts weren't touching. Has anyone else spent a full morning on a problem that turned out to be something dumb?

You still kept the warped battery as a souvenir?

Oh man, 6 years ago I had a Nikon D3 that wouldn't power on. I spent like 3 hours testing every circuit board, even ordered a replacement power switch assembly. Turned out the little plastic tab on the battery that says "push to eject" was just slightly warped (you know, from being dropped one too many times). A quick file job on that tab and it worked fine. The real kicker? I already had a working battery in my bag that I never tried because I was so sure it was a camera issue. I still find that warped battery in my drawer sometimes and laugh.
