Re: Electrical system install

No, not the keel bolts. On an outboard powered boat the system floats, the battery negative is your ground point.

I would also float the AC system, and not connect the AC ground to the DC ground as it serves no purpose.

Re: Electrical system install

Ah okay. Thanks. That's good news.
Any idea of any web sites that lay the basic principles out dummy simple?
Scary thing...I actually have a degree in engineering. Just not the type that deals in electrical.

Re: Electrical system install

If the panel you are buying is from Blue Seas they come with good instructions. Below is an example showing a 6 circuit Weatherdeck fuse panel.

As far as wire termination there is no better site than this: Marine Wire Termination Photo Gallery by Compass Marine at pbase.com

Thanks man, you rock.
Another question. On deep cycle battery terminals, you have two spots to connect connectors on each terminal, a fat one like on a car battery and a small one to attach with a nut.
You have an incoming charging run, and an outgoing load run. Can both of these be on the same spot on the battery terminal, just stacked on top of one another, or is there any reason to separate them and put say the charging on the small bit and the load on the big one?

Re: Electrical system install

Use the terminal with a nut. Stack the terminals as you will only have 2 or 3 including bilge pump probably - up to 4 is considered ok. I like to keep it to one connection per post, going to a bus and from there branching out, but it is necessary on larger boats with more connections.

The other solution is to put the connections on a powerpost like below and run only one to each battery. They aren't very expensive and you only need a 1/4" one.
