I have a Balboa 2000 LE controller with a 52320 circuit that suffered a terminal block failure.

The board was working but tripping a breaker and visibly arcing, and the block fell apart when I unscrewed the connectors.

The part does not seem to be available, so I was looking for advice on repairing it. A 5 circuit version is available, though I don't know if I could cut the connectors off and have the screws line up.

Also, a post from 2011 mentioned making pigtails to connect the power wires directly to the board.

Board replacement isn't necessary! If its the black connection, then locate the tabs that have "black AC" written around them. Pull the black wire out of its burned block, attach a "pig tail to this wire and spade connector on the end of the tail (s) and plug them into black AC tabs and your off and running again.
Where would the white an red connections need to go?
Thanks,
Louis
