there are several screws on the outside that clamp the npn transistors on the end and the schottky diode to the side which have to be removed along with all the screws that hold the pcb down on the bottom of the case.
you need to take it apart to get the pcb free and then turn it over and take pictures of the traces that go past those resistors R37-R40 and where they go back to the TL494.
they will return to either pin #2 or #3, can't remember, but it will be obvious.
make sure all the screws are loose first then the pcb will come out easily, you can pull the schottky and the npn's over a little if they hang on the sides but don't damage them.
worry about the power later. maybe you can try the balancing charger at 14V from the power supply to see if it will run with the 14V.
