I have a battery drain issue on my Searay 205 Sport. I removed the negative battery cable and then ran the red lead of my multimeter to the negative battery cable end and the black lead to the negative battery post. I was reading 0.27 Amps on the 10 A scale which seems like way to much. I started systematically removing fuses under the helm, then disconnected the stereo, the fishfinder/gps and finally the power lead to the alternator, but none of these changed the meter reading. When I removed the heavy red wire from the starter, the meter went to zero. I hooked the negative cable back to the battery and put my meter leads between the main red starter wire and the lug on the starter and the meter read zero. There is only one positive cable on my battery. Where do I go from here? The bilge pump has to be powered direct from the battery, but where is this connection? If the black battery wire is bad, could this cause the current draw?
