After delivering several more Dolphin boards it was time to assemble my system. I turned the key and as soon as the ready light comes on there was a gun like pop! I had forgotten to connect the igbt driver cables. At least the main board was not affected. All 3 igbt’s are shorted. I am lucky that my last customer was willing to give me his 3 spare igbt’s.
