I just got a Triton 544 and I'm trying to hook it up to a battery. Can someone confirm that on the rear of the 544, on the power connector, the bottom pin is GND and the top is +12 (to 14) VDC, and the two inner pins should be left open? In this configuration the fuse clears as soon as I connect the battery (which I know is a good 13.8 VDC with plenty oomph). --Andrew
