Shore power and battery charger

[16ACE27]

I agree that the batteries are done. As for the use/store switch, I always Leave a light on to visually see the power cut off when I push to the store position.

And that light comes on anyway when connected to SP or running the generator regardless of the actual position of the USE/STORE switch.

Yes. But I don’t use it in that respect when connected to SP or have the gen running. I often use the radio which receives main power from the house batteries

As an update, followed the instructions for my VOM for mA and above. It shows 5 mA

that's probably control power for the generator or levelers. Trip the 100 amp breaker and see if it goes away. But 5 ma is really nothing in the big picture.

That’s what I was thinking.
Thanks

The standard Attwood LP/CO detector that Thor installed back then only pulls about 70 mA. Somewhat insignificant in the larger scheme of things. That's about 1.7 AH/24 hour day.

It shouldn't drain the battery bank for several months by itself.

Well as an update for the last week or so, I installed a new chassis battery, installed a Powermax lithium capable converter, and installed 2 100Ah LFP batteries by Sourcepow. I didn’t get to the Li-BIM. The main reason is a combination of lack of experience and the ability to contort myself while doing a half situp under the coach. At that point, I had run out of time for a couple weeks. I may have to use a tech on that one.
Everything worked (as far as I can tell) on the first try. This is no doubt primarily due to following directions of those on this forum. As my time opens up again I will continue to test items, just to be sure. Although, I was able to start the gen and see that 120v made it to the microwave and saw 14.5 at the posts. I was not able hook up to shore power to check that part, but so far so good.
Thanks to all of you who share their knowledge and wisdom!

I forgot to mention in my follow up post. Prior to installing the lithium batteries, I had a small parasitic draw. Once I put the new LFPs in, the draw went to 0.00. This is also confirmed via the app connected to the BMS. What I don’t know and doubt I will ever look into is whether it was the bad FLAs or possibly the old converter causing the draw. I just thought it was interesting and others may have seen the same issue or have a possible explanation for future forum searches.
