Tracing 12V Power Paths for Starlink Install in Sunseeker 2400B MBS

[Freddie96]

On our 2022 Sunseeker 2400B MBS there's 12v power feeding the antenna amplifier inside the cubby over the entry door. Anybody know the path that follows to get to the fuse block? I need a separate 12v run for a starlink dc-dc inverter but can't tell if it travels down the wall or across behind the over sink cabinets.

Anybody have any input on this? My goal is to mount our starlink antenna in the skylight opening, wiremold non-metal flat raceway to the cubby with the network cable and mount the gear in that cubby.

Thanks!

Freddie

How fat is the wire feeding the antenna
You could steal power straight off that for the starlink?
Check wire size and power requirements

Try not watch tv at same time as internet browsing?

As the sidewalls are aluminum framing with solid foam insulation, no wiring is routed in the walls. Through, yes, but not in.
That leaves the cabinets, floor and ceiling. Depending on where the fuse/breaker box is located, most of my wiring is routed both through those cabinets and up through channels in the ceiling to devices in the cabinets or ceiling.
As Aussieguy stated, if the wire gauge is sufficient, you could use it for both applications, but you'll need to determine the current draw for all devices. If the wire is 14 gauge and has a 15 amp fuse, you could pull nearly that much on a continuous basis.
Independent of the path of that wire pair (source & return, aka power & ground), you can route a new wire pair through cabinets using surface mount conduits to manage & conceal the wire. Connect it to an unused fuse position, or if none are available, select something that is unused or little used. For example, I don't have an arctic pac on my unit, so I used that for the voltage-delayed charge line for the toad.
Keep in mind there are more sources than just your fuse/breaker panel; the panel for the slides/battery management system may have unused fuse locations.
My BCC box has the following:

of which I don't have an outside TV, a living room slide, electric seat, Kitchen slide, rear bedroom slide (but I do have a rear bedroom slide), arctic pac, or a subwoofer.
My main breaker/fuse box has 4 unused positions as well.

Good luck, let is us know what you find, and how you've solved this issue!

forwarded to our electrical team to see if they can give you some options.

Spent some time digging through all of this - thanks for all the info from everybody. I found that the antenna amplifier, amplifier switch and wifi-switch are all fed from a single #14 wire, yellow in my case. DC current draw on this circuit is about 200 mA with the antenna amplifier on and an additional 400 mA when the wifi is enabled. My need should be under 5A, so this will work fine. I'm going to add a switch that will control 2x. 12v DC 20mm fans moving air through my Starlink Gen 3 mounting - installed in the skylight over the recliners. I'm also adding some 20% window tinting above the inner skylight dome to keep the UV down a bit. I'll take some pictures so y'all can see my steps and final product.

I do appreciate everyone's input on this. Experience of others can definitely help and steer one from making bad decisions.

sounds like you were able to locate what you needed. Some info from electrical team for other members to review.

On the 2400B, the TV wire is ran up to the roof from the entry overhead cabinet and back down into the refer cabinet behind the refer then to the distribution center in the bed base. The fuse in the panel is labeled “booster” and provides a 15 amp circuit to that device.
