Hi
Does anyone have a wiring diagram for a 2009 Oceanis 37 please?

Should be one in the manual that came with the boat. Otherwise you may be able to download from the BeneteauUSA website.

Hi Doug
The one in the manual is too basic-it only a very high level schematic. I can't see anything relevant on the Beneteau USA website either...am I missing something there?

I presume the one you've seen in the manual looks like this?

The only other thing I have is a rudimentary sketch I made of the DC system:

Hi David

Thanks, yes, that's the one I have from the manual. Very basic! And I have a similar schematic to you!

But as an example, I can hear a relay clicking in the port aft cabin when I turn on the "Navigation" switch on the panel, which I guess is the heavy current supply for the autohelm: however I have no idea of the wiring colours, or location of other components like this.

That might be something that Ward at Beneteau might be able to provide. Last I saw their number was 843-629-5300. They've been able to provide some other schematics like keel bolt locations in the past.

For that specific example - I've never heard a relay click from turning on my nav switch, but it's possible the electronics were changed between 2009 and 2014. Our electronic rate compass is in that cabin so that's another possible source.

Rob,
I thought you were referring to the 12 volt wiring throughout the hull.
I was thinking of the diagrams from the WAGO distribution panel at the nav station
There is a diagram showing all of that wiring. Wires are all numbered at both ends (and they are mostly red)
Rudimentary engine room wiring diagrams may be in the engine manual. I would be willing to wager everything else will vary from boat to boat.
