i have had ab electric shock incident in the past, but nothing like your adventures.
Way back when, I used to work on switching power supplies. I am working away on one, and it was mis-wired in the High Voltage section (this design had a voltage tripler on the input side, so basically, it was sitting at somewhere around 500-540 Vdc). When I reached around the backside of the power supply to take some measurements, as per the test procedure, the high voltage cap discharged through me. The discharge sent me backwards, flipping me back , and I was passed out. When the assembly people heard my chair hit the floor, they called for help. I don't know how long I was out, but I woke up wondering why my boss was slapping me in the face. I came to, and my boss ordered me to go sit down in the company cafeteria for 3 hours, bought me a few Cokes, and I went back to work after that. They later disassembled the power supply and found out where the wiring mistakes were. Changed the assembly and test procedures.
