I have a 2003 2520 with two 200 hp 2019 Suzuki's (DF200AP). I am planning on moving my batteries (two start [Group 27] and one house (Group 4D]) to the pilot house. Question, where would you terminate the positive and negative leads from your engine harness? I was planning on either:
Option 1) install a BEP switch in the transom, connect the positives from each motor harness to the BEP switch, connect the negatives from each harness to a single 6 post buss bar located in the transom, run a connecting wire from the buss in the transom to a second buss bar in the pilot house, and connect the negative terminals on each battery to the buss bar in the pilot house. I would also run wires from the each positive battery post in the pilot house (three wires total) to the BEP switch in the transom. One downside to this is I have a positive buss bar behind the helm for my house electronics so the positive from the BEP in the transom (Stud F in the attached diagram) to the positive buss behind the helm is a long run.
Option 2) Same as Option 1 only instead of connecting each negative battery post to the negative buss in the pilot house, I would connect battery 1 negative post, to battery 2 negative post, to battery 3 negative post, to the negative buss in the pilot house. Not sure if this is an issue with the different battery Groups?
Option 3) - install a BEP switch in the pilot house. This would mean I would install two power posts in the transom to extend the positives from each engine harness to the BEP switch. The negatives would be the same for Option 1 or 2.
Any idea if any of these options are appropriate or if there is a better way? Thanks in advance for any input.
