Wire question

So I have begun poking around inside the hull to look at wires for adding a Victron shunt and possible installing a DC-DC charger.  Are these wires from the trailer harness (7 pin)?  4 of them are not attached to anything.

Thanks,

 

John

If all of your trailer lights and trailer brakes are working correctly when towing, it’s doubtful that those 4 unattached wires are related to the 7 pin harness.

I did a little more poking around and found the harness.  The black and white wires are 10 AWG 👍🏻 So I have that going for me.  😁FBBF5BEE-A53C-4AAF-8B76-35817C330CF7.thumb.jpeg.992b98ae08d3da287f92901bdc814b37.jpeg

As a side note, since I've given Oliver a great deal of grief on the forum over this - the wiring and general cleanliness of the hull space on these new trailers is a tremendous step up from where they were a few years ago.  Nice.

Also @SeaDawg, those photos show the new insulation you were asking about.

I have a couple of questions about the OP's pictures.  What is the relay for in picture #1 and the water supply lines in picture #3 are on top of the grey water tank and that seems to be a new location that I haven’t noticed before.

I'm not sure what that relay is.  It says LED lights on it but which ones I am not Sure.  Those PEX pipes are just a couple spare sections in case a repair is needed.  For anyone who has relocated their negative wires from the battery compartment to a bus bar in the hull, where did you place the bus bar and did you have to rework any cables?

 

Thanks,

John

I added a mounting board on top of the wheel well and placed everything there. You can see it in this post - 

I can’t say about reworking cables since I did all of mine from the start.  But I’d imagine that you’ll want or need to make up a few cables.  It’s easy if you get a pneumatic crimper off Amazon - it will seem like a silly purchase for one job but it will make the task go so much easier.

If the spare sections of PEX aren’t secured, I would recommend that you do that.  I have a spare section floating around out of sight in the lower hull.

These pictures should be self explanatory, but if not, let me know.  I did rework the B+ and B- cables to work with the battery cut off switch, battery + and -, and the Victron shunt.

And I will second Overland's suggestion about the hydraulic crimpers.  With careful planning, you can crimp new lugs on while the 4/0 cable is on your work bench or while the still in the lower hull.  I removed my B+ cable from the main Oliver fuse and the inverter, which enabled me to make up those shorter cables on the work bench all out of the original cable.  The Oliver B- cable was moved from the inverter to the shunt and I purchased a new 4' piece of 4/0 and lugs to complete the negative side cables.

Mossey:  Thanks for the pictures!  Well done.  

Am I correct in thinking that at the top of the photo you have power coming from the right, going to the left through a fuse block, to the Master Switch, to the B+ terminal block below?  

If so, what size fuse did you use?  Or did you just reuse the OEM 300 amp fuse block?

Thanks,

GJ

PS:  For those looking at this same process, Blue Seas offers both a 300 and a 350 amp master switch.
