Identification of Circuit in Battery Box

[Russ-USA]

Hello!
On our new/used 2019 Vista I finally got around to looking closely at the battery box. Winnebago has not changed much since our 2004 Sightseer it seems design wise.

What is different is there is a 12AWG circuit that goes through a 20Amp circuit breaker (blue and black wires) connected to the house batteries. Does anyone know what that circuit connects to? I looked over some wiring diagrams but could not find it.

(I also will need to clean up the battery box and hold downs when the weather is warmer )

Thank You!

Just a guess, might be 12 volt charge for a toad on the 7 way plug.

I would be unusual for for Winnebago to use red or blue 12 or 14 guage wiring. My thoughts would be a previous owner installed circuit (it is protected) for some item that is 'hot' all the time. Maybe a small inverter, toad or???. Look for a device that is not a standard Winnebago item. Maybe a medical device that has been removed.

Thank you for the ideas! I'll have some time tomorrow to trace through the line and see where it leads.

That is an excellent application for a tone generator wire tracer. Unless you plan to use it frequently try borrowing one from Autozone.You leave your CC number with them and upon return they give destroy the paper with your CC #, making the loan free of charge. If you fail to return the tool they buy a new replacement with your CC #.

Mystery solved.

The cable routes to the bay next to the battery box and terminates in a 12v power outlet right next to a 120v outlet.

This is very convenient since I was planning on installing a trickle charger for the chassis battery, so this is perfect.

Thanks for the update.
