    Atlas 550 power supply fuse keeps blowing after new DALLAS battery clone installed on board.

        The Dallas battery chips were failing on three of our Atlas 550s.  I bought TI bq4287MT-S82 replacement chips. We tried replacing the bad chip on one board, but had no luck.  The remaining two boards were sent out to be soldered. The boards came back and I reassembled the chassis. Now when I turn the power on the 250VT2AL fuses blow. I'm pretty sure I reassembled correctly. I verified against pics. I checked the power cable. Is there possibly something I'm missing or are these resoldered boards no good at this point? Or possibly the chips?
