Cabin Battery

[BPetz]

2014 Solera,24S MBS. We have been plugged into shore power (at home) for about a month. Was always getting at least 3 light on panel in regard to battery. Hasn't been a problem until now. Batteries were replaced in April 2022. Any guesses?

So what are the symptoms that have you concerned?
Those indicator lights only show that the battery is charging, not the health or charge on those 'house' batteries.
Do you have the batteries connected via the battery disconnect switch? They should only be disconnected if you're storing it without electricity.

The symptom(s) is no cabin power. Don't even have enough juice to start the generator

No one knows what led lights on your panel means.

For entertaining the cat i believe.

The assumption is you batteries are either turned off or dead or need charging. .

Test the battery terminals with a volt meter. Then plug in the shore poser and see what the voltage is. If the batteries are dead then it will take overnight to charge them.

You then have to turn the shore power off and wait 2 hou8rs then read the voltage again.

Generally batteries read 12-12.6 volts. 50% to 100%

When shore power is on, the converter, is turned on the voltage will read some value over 13.1 volts.

If those are the original car batteries in the rig they are likely dead. Guess!

Probably dead batteries. I suspect that the battery disconnect was in the wrong position and the batteries were not being charged. Since you had them replaced in April 2022, they aren't being charged from shore power.
This is a motorhome, right? When you run the engine, the batteries will be charged from that engine (assuming the battery disconnect is not engaged. It will take some time to charge them though.
Your other 'work around' would be to put a battery charger on the house batteries.
Have you checked to make certain you haven't blown a fuse in the house?

If you have the standard 4-led light panel, 4 lights indicate charging, 3 lights indicates full or nearly full battery, but not charging.
