Engine Faults On Force HD

Lately our 2019 Force HD engine has been starting sluggishly after sitting for a week or more. I also get get some fault messages on the dashboard. I am guessing this may be due to battery issues. I live in San Antonio, so it doesn’t get really cold here.
I have never used the switch at the entrance to the cab to disable the engine batteries. Should I start doing this regularly? What period of time between engine stop and start before I use it?
Any other suggestions?
Thanks.

What is the code?
I turn my battery switch off every time I shut down, my batteries are now 5 years old and I have never had a problem ( of course I will now since I am talking about it. LOL).

Do you keep it plugged in when not in use?

Maybe the Force is different, but on my Isata 5, the battery disconnect does not disconnect the chassis battery, only the house batteries.

I keep mine plugged into a 15amp power at all times when stored and the charger keeps both the house and chassis batteries in good shape.

Yes. I keep it plugged in to 20 amp at home when not in use. I think this charges only the house batteries. I have two shut offs. One for the house and one for the truck.
I get 3 errors
SA: 11 ABS SPN: 803 FMI: 4
And
SA: 3 Trans SPN 2003 FMI 31
And
SA 3 Trans SPN 168 FMI 4
And today, a new one
SA: 33 Bulkhead SPN 524255 FMI 7

Doesn’t seem like these are battery errors, but the only thing that seems to be wrong is a sluggish start when it hasn’t been started in a while.

The BIRD charges both the House and Chassis batteries. See this document.

Also, search the forum “Titles Only” for keyword BIRD and you will get a wealth of information. The BIRD solenoid is know to go out frequently and some have moved to the BIM which is what is in all the newer models.

Great info. It’s going to the dealer tomorrow for some other issues, and I will certainly add this to the list.
In the mean time, I’m still interested in who uses the truck battery cutoff switch, and when.
Thanks.

My Force HD stays plugged in 24/7 at my storage unit. I hit the disconnect by the drivers seat and by the front door. The BIRD will keep both sets of batteries charged.

Just to be sure, the BIRD works with normal household current of 15 or 20 amps?

And it will still charge the coach batteries even if the disconnect by the drivers seat is used?

I had the Isata 3 for three years and now the Isata 5 for one year. I am always plugged into 15 amp and I never use the battery disconnect. If you are plugged in you should not need the battery disconnect at all. I have never had even a low battery in four years following this method.

What dealer are you using for service? Where they the selling dealer?

Holiday World in Katy. Bought it there and have been using them for service.
Seems like since I do keep it plugged into 20 amp at home, and the chassis batteries are not staying charged, it may very well be the BIRD.

My money is on a bad BIRD. If you are still under warranty, then they will probably replace with the same thing. If you are paying, I would swap to the new BIM they are using on all the newer RV’s.

Our 2017 Isata 3 had the BIRD and our 2021 Isata 5 has the BIM.

Does the BIM work with AGM batteries, or do you need lithium?

The BIM is for AGM batteries. They have a Li-BIM that is made for lithium batteries. Same mfg for all of them.

Thanks. I’ll see what they say about warranty.
Where do you get yours serviced?

Over two RV’s and four years, I have yet to need to go to a dealer for service. I was thinking Holiday World would be where I would head if a need ever arises. I tend to do small things myself. If I ever had a really major issue, I would head to the factory. My selling dealer is further away than the factory.

A simple check with a meter will tell you if the BIRD is working.

I’m jealous. Most of this stuff is way beyond my technical and physical ability.

Truly appreciate that.
Perhaps we South Texas Dynamaxers can get together for a couple of days at a nearby campground some time soon.
