A leak is bad for the environment, so they have to verify before filling.
So the AC was blowing a fuse from what? It was just running high without resistance or something? It seems odd if that was the case because an empty system wouldn’t do that normally.

The initial vacuum test held for whatever amount usually required for testing like normal so at some point the seal on the crimp let go or just got larger as the days went by. I lost a hair over half a pound pound of refrigerant.
My guess and from what I can tell is that the compressor was working OVERTIME with the leak which caused it to "lock up" or just require more energy to trip the clutch which then fried the fuse. The day before I thought it was weird the fans kept kicking on an off like crazy but didn't get a chance to look at the reason for it.
So when I got home yesterday from the shop I did a test. I took a jumper wire to the clutch directly from the battery while the car was running and it labored to kick over the first time. After a few cycles it tripped just fine so I plugged it back into the stock harness. It didn't blow the fuse once after cycling it a couple times. Granted this was a dry system so I kept it small short cycles just to see. Either way I think that kinda proves my theory. The compressor was close to failure I think. Hopefully it's not trash but we will see once it's all hooked back up.
