Shore power and bad batteries

Another Berk pulled in at the park where I'm currently parked.
During setup, he was operating the jacks at the same time his wife was operating the slides.
Everything died on them. They are sitting there with no leveling, one slide all the way out and 3 in.
A mechanic came by and decided it was probably his coach batteries had died so they are waiting on a new set of batteries to arrive.
Would the coach not get power from shore if the batteries are bad? That doesn't make sense to me.
He's got full power to the chassis and if he runs it a few mins, he gets power to the coach.
No power to the gen ( is it powered by the coach batteries).
Also, he's got a 2014, but no idea where the chassis batteries are located(unlike mine where they are on a shelf directly above the coach batteries)

On my 2014 the coach batteries are rear drivers side 3rd compartment from the back end I believe. Chassis batteries located all the way to the rear compartment with the inverter in the compartment in between the batteries.

I would start checking some fuses and/or reset breakers. Running both at the same time is a pretty big drain, although they've probably done this before. The batteries would be easy to check to see if there is a dead one in the group. I would check this before buying new batteries at $100 a pop.

To answer your question, if he was plugged in at the time to shore power it should not have lost power. Sounds like something else is the culprit.

They found the problem. When they operated jacks and a slide at the same time, it blew a 150a fuse that's located in the battery compartment on the back wall above the batteries.

Why would anyone operate the slides and the jacks at the same time?

Why would anyone operate the slides and the jacks at the same time? The RV should be leveled with the jacks before any slides are deployed. You can damage the slide mechanism if your RV is not level when you deploy or retract the slides.

Also if the RV is set up to run the jacks and/or slides from the coach batteries and the batteries are dead being plugged into shore power will not help. The batteries have to have enough charge to operate unless the jacks and/or system is designed to switch from 12V to shore power.

My jacks run off of the engine battery and the RV has to have the engine on when jacks are being deployed to keep from getting into a low voltage condition. My slides run off the coach batteries.

What you said about your jacks is interesting.
My jacks won't operate with the engine on, they are locked out. A nice safety feature. Don't know which batteries power them

You don't have a Berk, do you?
