Wiring Diagram

[S/V SoundWave]

We have a great opportunity to rewire the boat now, since the headliner, cabin fascia and sole are being redone. We're talking starting from scratch rewire. I have a blank canvas.

Now in planning/diagramming stage, and will start with the original wiring diagram from the manual
(Thanks to those who compiled it on this board, electrical section parsed out is attached)

There is a wish list, with of a couple of additions, e.g. lighting updates, USB charging receptacles, communications, cockpit lighting. (Plus a rocking music system, of course

If anyone has updated their wiring, and feel like sharing your wiring diagram it would be a great help. I tried to scour the forum first, sorry if this is a repeat thread.

Any ideas or advice is much appreciated!

I posted my revisions to the wiring in a recent post "History" in the Diagrams attachments.

I had a professional replace my electrical panel with a Blue Sea panel... make sure you know the current ABYC wiring rules. I was thinking of putting an AC outlet under the dining table, so I could plug in a TV and/or laptop. It should be easy since the wall backs up to the under sink cabinet. Also, I wanted to add a cable connector for the TV cable when in my slip. Now it goes through an open hatch and is a tripping hazard going forward.

I also rewired my entire boat with the help of an ABYC electrician. We built a new panel and installed all new breakers (both AC and DC). We used tinned, marine wire throughout the boat. Every AC outlet was replaced with a GFCI (7 of them). All lighting was replaced with LED fixtures.
While the headliner was out I lined the cabin top with aluminum bubble wrap type insulation.

I really appreciate this forum.

Jim, I found that thread with your diagram and the others, too. Thread title was "Battery Circuit", I had failed to search either of those terms. Thanks helping me find the diagrams.

Helene, you're right, and I will have an ABYC certified electrician proof the design, and do the terminations. (got the idea from reading Thomas' post from another thread during my diagram search) to really head up the job, I will be the helper. Guy does pretty panel work. I like the Blue Sea website and they have a good reputation

Thomas - I like your plan, I'm kinda copying it, though had only thought of 6 outlet locations, and LEDs. When I put up the new headliner, I'm thinking about k-flex insulation sheets and Parkland waterproof panels. Plastic over fo No vinyl. Jury is still out on that, that project is slated for February or March, and that will be a different thread.

Thanks, everyone, for your help!

Along with many, many other projects Pilgrim's electrical systems are under going a complete overhaul. We have reached the point where some of the new systems are being installed.

We created w new panel for the battery selector switch and the bilge pump switches...

New Battery & Bilge Pump Switch Panel

This panel was installed in the same location as the original.

New Battery & Bilge Pump Switch Panel Installed

• Sep 17, 2015

We have not yet run the appropriate fuse and large gauge wiring to connect the relocated house bank to the selector switch. Here is a link to our Battery Relocation Photo Album for additional detail on this project.

We installed two plywood panels along the hull outboard of the nav station. These panels will allow us space for mounting wiring, buses, terminal blocks, and other equipment associated with the electronics.

Installing Buses & Terminal Block Behind New Panel

In the image above...The dual, long buses on the left are for DC Neg. The dual long terminal blocks in center are DC Pos. The short covered block in center is a central fuse block for the electronics. The AC Pos terminal block is on the upper right. The AC ground and neg bus bar is on the lower right.

The new Bass DC/AC Circuit Breaker Panel is mounted aft on a vertical hinge.

Back side of new electrical panel in nav station

• svpilgrim
• Sep 17, 2015

This panel has space for 20 DC breakers and 10 AC breakers. It also includes analog amp & volt meters and a reverse polarity indicator for the shore power connection.

New Electronics and Electrical Panel in Nav Station

• svpilgrim
• Sep 17, 2015

The forward panel at the nav station is mounted on a horizontal hinge. This panel contains currently contains (clockwise starting at noon in the image above) the high water alarm, Garmin Multi-function display, BlueSky Solar Charge Controller, Victron Battery Monitor, DC Outlets. We left space for future devices to be installed in the panel.

Here is a link to out Nav Station Refit Photo Album

We have many components awaiting install.. New AC shore power outlet, AC source selector switch, new galvanic isolator, new dual bank battery charger, AirX wind generator, solar panels, etc.
We have already completed the majority of the wiring in the head and galley.
We have yet to begin to address lighting, but do plan to use exclusively LED fixtures.

So many items on the to do list. Better get back to the boat...

Here are the schematics of Pilgrim's new primary 12V DC distribution

Despite spending hours upon hours spread out over months drafting, researching, modifying, testing, modifying, modifying, modifying the schematic, the design continued to evolve throughout the installation. The install is now complete. The heavy rains that flooded the Carolina's over the past couple weeks provided the perfect excuse for locking myself away inside Pilgrim installing the primary 12V wiring.

The schematics were completed using Google Draw. If you would like to view the Google Draw files, with active hyperlinks, use these links:

I welcome any questions or comments about our design.

Jeff, where are your three house batteries located?
Quarterberth? I didn't see a compartment with them in it, or big enough maybe?

Dave,

We moved the house bank to the void under the salon seat just forward of the galley sink. We currently have four 6V AGM batteries in the box. We plan to purchase six new 6V AGM batteries prior to moving aboard.

SV Pilgrim House Battery Bank

• svpilgrim

We moved the house bank to under the salon seat just forward of the galley sinks.

We fabricated a fiberglass w/ plywood core box to fit the space below the seat and house the battery bank. The box is mechanically fastened the vessel's IGU. To secure the batteries in the box we ran two 1/2" stainless all thread rods from the forward face of the seat through the partial bulkhead just forward of the sink. The rods are sheathed in 5/8" nylon hose across the top of the batteries.

House bank access via removable panels under the cushion

We used the face of the original drawer to create a hinged access panel on the side of the box. This provides access to the bank's 300A fuse, the on/off switch, and the battery monitor shunt.

Used original drawer face to create a hinged access panel for house bank fuse, on/off switch...

We completely rebuild the lockers under the quaterberth. The starter battery is now located far forward under the seat for the nav station. The starter battery share the locker the the battery management control panel and the automatic charging relay.

Starter battery is in a locker far forward under the quaterberth. It shares the space with...

All the new wiring is marine grade. The runs between the battery banks and the battery control panel & the neg runs between the banks the the engine block are all 2/0 gauge wire.

All good. Here is a simple wiring diagram that worked for me. Some extras that may assist others. KISS
