Replacing J3 on a KPA100

 
   
  I was wondering if any of you have replaced J3 (the Anderson Power Pole Connectors) on a KPA100.  The hot side (red) was slightly deformed when I did not have a good connection and the connector heated up..  The black APP is OK.  Looking at the the instructions, it would mean taking the board off the heatsink...something I am reluctant to do.
   
  I was thinking about just cutting the two leads...and replacing the connectors...soldering the connectors to the cut leads above the circuit board.
   
  What's the guru's thoughts?

Lee,

I would think you could remove the J3 connector from the top side of the
board.
Remove the connector mounting plates first, then heat the connection to the
PC board and you should be able to pry up and remove the ends of the 'L'
shaped conductor pieces from the board.  You will have to remove both
because the red and black housings are keyed together.
After everything is free of the board, you can clean up the solder with wick
or a solder sucker.
Put on new housings and replace/resolder (mount the hardware before
soldering).

Hmmm, if only the plastic is damaged, why not pull up the 'tongue' of
the connectors with a small screwdriver and pull them out of the
housings?  Then snap them into new housings, and Bob's your uncle!
