Power Distribution Board.

There is an active circuit in the item that converts 12VDC to 24VDC. You probably let the smoke out.

I think the new smoke cost about $ 189 from AndyMark. About the same cost as a college textbook. You can write off the expense to a life experience 'tuition. I wouldn't waste time working with the board.

Working with electricity and machines can be hazardous to both machine and man. If you can get some procedures in place for working on machines then both man and machine will be safer. At least no one got hurt, just some feelings.
