ANOTHER electrical question...

Ok I have a new to me 2009 Keystone Passport and long story short the previous owner had 2 Marine batteries hooked up with a switch that will run 1 or both batteries or completely turn them off when not needed. My problem is when I turn on 1 or both and not hooked up to shore power none of my outlets will work and I can't reset my GFCI outlet. The batteries work and have juice because the hard wired radio/cd player, lights and fridge all work. The tv doesn't bc it's plugged in to outlet.
When plugged in to 30 amp camp ground all is good.
Appreciate any thoughts, thanks in advance.

Sounds like you don't have an inverter to change 12 V to 110 for those appliances.

Read the owners manual to determine if you have an "Inverter". They take battery voltage DC and change it to AC. A select few outlets may be served versus the whole RV. Most often you will find smaller ones running televisions and receivers. It takes a powerful one to run a microwave for example.

The 12volt Side of Life (Part 1)

Read both parts for a better understanding of RV electrical systems.

Does your Keystone have an inverter?
If it DOESN'T your 120VAC outlets will not work, (and your GFCI outlet will not reset), unless you are connected to shore power or a generator.

Ah ha....I will check. Now for the total dummy question, where might one find said inverter?

Follow the battery cables. The are usually mounted close to the batteries.

Find the owners manual and read it carefully. It will show if you have an inverter. No sense in following wires to components you may not recognize at this stage of your rv experience.

It make sense if the previous owner installed one, along with a battery A / B switch.

A "converter" is not an "inverter".

The brochure does not show an Inverter. It does show a 55 amp converter.

If you take time to read the link I posted it will shed some light on what they do.

The Batteries are 12 volt. They power lights, Fans, the water pump, furnace, control power to water heater and furnace and A/Cs Steps (may be on the other battery) slides and jacks (Again may be on other battery) THey do not power outlets, Microwave or Television Or the Fridge (Operational power) or A/C (operational power) UNLESS you have an inverter..

Inverters are optional.. Sounds like you do not have one.

I recommend a battery upgrade if you get one . MARINE/deep cycle are really starting batteries with lip service to the deep cycle.. True DEEP CYCLE are far better for RV use.

Most travel trailers DO NOT have an inverter and can not run 120V items without being plugged into an external power outlet, such as at a campground or on a generator). That's why the radio, fridge, lights, furnace, water pump, and hot water heater run off 12V and/or propane.

My 1999 motorhome DID NOT have an inverter either.

All the stuff runs off the 12 volt batteries except the stuff I run off the inverter I installed.

Is it beyond reason to think someone could have put one in ?

All I suggested was a look see on a second hand RV.
