Lavezzi 40: Adding DC branch panel

[KenR]

While planning the installation of a new DC branch panel, I realized I was going to have issue with the negative bus in the Nav station. The existing negation bus using a 12 AWG wire is inadequate. The positive bus is using a proper sized wire. The existing negative bus has few wires attached to it. Where are the remaining neg wires attache
d? Is there another neg bus somewhere which I cannot find? I do not desire to drag a new large neg bus wire through the boat to a 80AH breaker panel. However, I fear it may be my only solution. What alternatives do I have?

I would be surprised if the negative bus follows the positive distribution panels, that's not necessary. My boat has a negative bus with large cables run from the house bank to 4 strategic places on the boat within easy reach of most appliances.

Do you have a wiring diagram for your Lavezzi?
It should show the neg runs, I can dig mine out if you don't have one.

Hi Dragon Lady, I was reading your post and noticed that you have a Lavezzi wiring diagram. I have not had any luck in finding one. We just bought a 2008 Lavezzi 40 and are starting to upgrade it so it would be etremely helpful if we could get a copy of yours. If possible could you send one to me?

Hi Dragon Lady, (sorry KenR, my panel is like yours and electrics on every boat ive owned are different, messy, and more complicated than designing a satelite...) ive also got a request. I’m hauling out my 2007 Levezzi next week ,if you have a manual that shows strap position for travel lift could you rely them as measurements from the bow or stern? Would appreciate it very much , my “manual” is useless, small and in French. Between the yard and myself we’ll muddle through but it would be good to know.
Thanks Pete.
