Parked for a while

So I haven't been traveling as much as I would like lately and my 3170ds has just been siting for a while. I regularly run the engine and the generator but the last time I tried to start the generator it hasn't started. The temperature has been warm and the battery level was fairly low so my question is, should the battery be charged more to get the generator to start? Also, if I am plugged into regular house power to charge the battery should the disconnect switch be set to in or off? Thanks for any help.

On. If your batteries are not strong enough to crank the generator then they are over discharged.

Also, you can tie your chassis battery to the coach battery temporarily using the switch located on the base of the driver seat (on mine) or on the dash on some. Takes two people, one on the spring return switch and the other starting the generator. You can also use this switch to start the engine off the coach batteries.

Our unit will charge the coach batteries with the switch on or off when on shore power. I think by running the engine for a short period then you should be able to start your generator. Switch has to be on for starting the gen.

For 2014, at least the early year models, they did not charge with disconnect in OFF, I believe that did change in later models.

If you have it plugged in then your batteries may be in need of water or changed
We just had a thread on bad batteries
My Indy RV repair guy said the batteries of today are really not great and 2years is good (all the recycled lead isn't giving the life they once did)
Interstate was making a pro series with new lead but demand was too low
All the penny pinchers out there would rather hassle with these problems than spend $30 bucks more for a good battery
Not being able to start my Gen set with what I thought were fully charged batteries is what set me on my quest to figuring out that my one year old 2860 had junk batteries even though I checked and filled the water and kept a charge on them

I replaced my batteries the second season of camping. Went with true deep cycle Lifeline AGM batteries. So far so good.

Just plug it into the 120 volt house current and leave it plugged in. The batteries will charge and you can excerise the genny all you want. Just run the AC for a load. The more you run the genny, the better.

I'd like to get a definitive answer on whether or not my unit 2014. ('13 chassis) 2860 needs the battery switch "on" to charge while plugged in at the farm where it's parked
I don't want to waste electricity for all the plugged in items (TVs,Micro,clocks etc.and anything else that uses residual power)

If by "ON" you mean battery not disconnected then yes.

Residual power use is minimal and there are loads such as battery controls, generator controls, slides, awning power etc that are directly wired to the battery and not shut off through the switch. If you are concerned why not disconnect the batteries and use a "Battery Tender" to maintain the batteries. IMO it's a better choice than the onboard converter since a Battery Tender is specifically designed to maintain batteries and not other functions.
2014 was around the time FR swapped to a Power Dynamics Converter which allows the switch to be off and still charge the batteries on shore power. Check and see if you have a Power Dynamics Converter, if you do you can leave the switch off.
