RV battery

[Arricejr]

New rv welll new to me question is should my house lights
Be pulling power from my starter battery? Or better yet Starting battery seems to be powering house lights and starting. Coach too it was like this when I got it I feel this can't be right help

Normally all interior lighting is off the house batteries.
For a better chance of some one answering the question post you make, model, and year of the RV.

your inside lights should be running off of your deep cycle battery, the starter should run off of a normal battery.the previous owner might have the batteries hook up wrong.check all connections at batteries.

I am confident in stating your system was not designed to run lights from your starter battery

With one exception all lights inside the RV should be "House" items powered off the HOUSE electrical system.. That one exception is a "Dome Light" over the dash that is controlled by the headlight switch.

Exterior lights.. Normal Vehicle lights, (Head/Tail/Marker/Turn/stop/Backup/Fog) are chassis.. Porch and scare lights are House.

And for those of us who live in this country's most populated state.. The Great State of Confusion (Joking folks)

When you START the vehicle.. a device called an ISOLATER connects the house to the Chassis system Thus the Engine alternator is now powering all lights, indoors and out..

Plus. if this isolator fails... And they do fail, in the "Connected" mode.. Well, then the chassis battery and the house battery remain connected.

What am I looking for? How should they be

Every thing from the drivers seat forward is run off the chassis battery in my Hurricane: map lights, power seat, front bunk, fans, windshield wipers, jacks, radio, etc. The drivers compartment has it own 12 volt fuse/relay panel own by the drivers left foot, 14 fuses and four relays.

I run it all off the same for past two years

It is VERY common for the battery isolator/combiner solenoid to fail. While it is possible to fail in the connected mode, it's much more likely to fail in the unconnected mode. One quick/cheap/common remedy for the problem is to simply connect all the batteries together. This can be done in a few ways. One common way is to move one of the battery connections at the isolation solenoid to the other side. There'd be an empty stud on the solenoid if that was done. A second way is to just add a jumper between the battery banks. If all the positive lugs are connected with cables, that's what was done.

Not familiar with your Deere chassised Overland though, maybe some one familiar with them will chime in with more ideas.

I think it's a Oshkosh chassis what made me question this is as soon as I connect the coach battery meaning the starter battery house lights work? Is that normal if house battery is not connected

If you are plugged into shore power, yes, as the converter or inverter will supply 12 volts to the lights.

[Arricejr]

Not plugged in that's the thing
