Wiring Diagram for Newer Hawk?

[So Cal Adventurer]

Hey Guys

Does anyone have a .PDF or similar with the wiring diagram for a newer hawk?

I've searched their website, and unable to find what I am looking for.

Looking for wiring layout, specifically the battery stuff.

Thanks
Kevin

no, but what do you need help with?

no, but what do you need help with?

Ordering a Hawk soon. My truck already has dual batteries, an isolator, fuse block, etc..

Want to see how the hawk battery is wired up and how to tie it into my existing setup.

I have (2) 100 watt solar panels on the truck now and trying to decide if I want the camper on stand alone solar or if I want to tie it into the truck.

Here is my build of my truck so you can see what I’m working with:

Kevin,

Nice build page. You know what you are doing. My biggest presence on this forum is via this thread - http://www.wanderthewest.com/forum/topic/13230-i-need-more-power-scotty/

And there are several more knowledgeable people here regarding electrical bits!

From what you say on your build page, the biggest thing that jumps out at me is that you move around a lot, and don't stay put. That said, big solar arrays are likely not your best solution, and you will want to maximize the charging you can get with moving / truck is running.

I've got capacity to do either on my build, with 100A via the alternator, or 465W of solar. Your Toyota has a notoriously stingy alternator, so you will need a DC-DC booster to convince it to send decent volts/amps to your camper batteries. CTEK D250S is a good start

Bernard uses one and is quite happy with it.

In addition to that device, you will want to upgrade the wiring from your camper batteries to the truck alternator, to something like 2G or beefier. I added gauges in cab so I can see what is going on, and a remote switch for the Blue Sea ACR, so I can connect and disconnect the camper from the truck as necessary.

Thanks...

Yeah, I currently use the Perfect Switch isolator and have been using them in various builds for over 10 years, love them. They keep both truck batteries tip top. Just trying to see if I can add a 3rd (camper).

I have gauges for both batteries in my truck also.

The plus side is, I already have a marine grade bulkhead Post with 2ga attached to it mounted right at the front of the bed. So the wiring for the camper for this setup SHOULD be fairly straight forward.

My whole truck is wired up in 2ga for that very reason, maximum efficiency.

I would almost definitely upgrade the camper wiring to 2ga as well. That’s kind of why I was looking for a diagram. How is the stock wiring run on the Campers? Am I going to have to remove walling to get to wires?

As for always moving, yes, but almost all my photography is done at night. I’m isually parked and sleeping during the day. Hahahaha.

Appreciate any and all feedback.

Thanks!
Kevin

The wiring between the camper-to-plug and the camper battery is pretty simple: the wiring is ~12 AWG into the camper, there is then an auto reset circuit breaker (50A?) then a Blue Sea SI-ACR battery isolator, then the battery.

I would think you would want your solar on the camper, as if it is on the truck it will likely interfere with the camper cab over. If you already have dual batteries, maybe you don't need camper batteries at all and can just run the camper of your existing aux battery? Three separate battery banks seems a little silly and heavy.

Thanks Rando..

Yeah, the solar panels are currently mounted on my Leer Fiberglass shell. They will be moved to the roof of the camper when I get it.

I’m agreeing 3 separate battery banks is overkill and silly. That’s what I’m trying to iron out and plan now.

The truck currently has an ARB fridge that is basically always running. The hawk I’m getting has the 85L 2 way.

Would be great to keep both fridges for maximum room and ease of access when riding Motos and just want cold water but not sure it’s really feasibile.

Still looking at all options.

Also, where is the wiring from the solar plug routed? Is that easily upgraded?

Thanks

So cal, just popping in to say awesome website. Fantastic documentation! Everything looks professional 110%.

Thank you very much for the kind words.

I’ll be doing one on the camper too

The wiring from the solar plug is inside the roof, then behind the front lift panel, and then under the bed. So no, it is not easily accessible, but there is also no need to change it unless you were planning on running a HUGE solar array.

One other word of wisdom as you plan out your build is to keep weight in mind. No matter what, you will be over the GVWR of your Tundra, and I personally don't think that is the end of the world. But the more weight you add, the larger the impact on handling, longevity, safety etc, particularly if you plan on hauling motos as well. As you plan on adding thing to your camper plans, consider the cost/benefit ratio and the weight/benefit ratio of each addition.
