I replaced my three bilge pumps and floats this weekend. The first two work fine but the aft bilge pump will not work. I wired black pump to black ground wire, the larger brown wire with the red stripe to grey (float switch), and two brown wires to grey (other float switch wire) and to brown from pump. I validated that the pump is working by touching the battery with the wires. I also put a meter on the wires and found only the smallest brown wire was hot. I did try to hook the hot wire to the pump but it did not start the pump. Any ideas?
