Vent: A single loose wire on a panel cost me 4 hours of troubleshooting

I was swapping out an old DSC panel for a new Honeywell Vista last Tuesday, and after I powered it up, I kept getting a trouble condition I couldn't clear. Turns out I missed one of the ground wires on the transformer that was barely hanging on inside the old metal box. It took me 4 hours of checking zones and reading manuals before I noticed it. Has anyone else spent way too long chasing a dumb connection like that?

Oh man, I had a buddy who spent like two hours chasing a phantom short in his old pickup. He was pulling his hair out checking every connection and switch. Finally realized the ground wire from the battery to the chassis was just rusted through, soon as he replaced it the truck fired right up.
