Seems like someone already tried to seal the cable holes using a paper bag and other stuff. Might be worthwhile properly plugging those holes using fire retardant sealer (not paper which is easily flammable). This might also prevent Mr. Lizzards friends from looking around for him!
Been taking my son out on side job's since he was 13. One day, I powered down a unit and asked him to do a visual inspection. Next thing I hear is him throwing up and gagging. Their was a rat that got caught between two phases, it was some nasty shit. 😂😂😂😂😂😂
Great Video. Good job and nice work. Thank you for sharing. Mr.lizard got barbecue. May I ask, if human touch DC voltages , can human get electrical shock or zap get hurt from that ?
@@subcoolHVAC To add to your comment, high-voltage DC is actually more hazardous than high-voltage AC. AC at least gives you 60 times a second to get loose, DC gives you none.
Nice video, why didn't you diode test the 6 diodes in that bridge rectifier? A lizard alone wouldn't blow them high current relatively low voltages compared to thousands of volts lines. More than likely IGBTs are blown or the full wave bridge rectifier.
You could do that with a high value power reistor. Don't short it to ground. If you short it you'll weld stuff on those monster capacitors (or damage a board etc.).
The board where they were measuring the DC bus voltage appears to already have a bleeder resistor. There's a lot of energy there, it just takes time. Absolutely, do not short it to ground.
