New house batteries dead in 24 hours, why?

I have a 2005 American Tradition and I installed 4 new 6 volt house batteries a week ago today. Batteries were fully charger and started the generator with out problem. We left yesterday for a 60 mile trip to a campground. Hooked up the 50 amp service and everything seemed to be OK, Now 24 hours later the CO2 sensor went off because of LOW VOLTAGE. I just checked the shore power and I'm reading 50 Amps/123 volts coming into the coach. I checked the inverter/charger and the small green lite was blinking once every 3-4 seconds, but the DC lights are very dim and there's not enough juice to start the Generator. Any help would be gratefully appreciated.

Sounds like the charger is not working properly. I am assuming the charger is part of the inverter. The inverter my by bad and In needed of repair or replacement.

This will cause the 12 volt systems including the inverter to drain the batteries.

Use an external battery charger for now and have the inverter checked.

Here is what I would check.

1. what does "small green lite was blinking once every 3-4 seconds" mean in relation to operation of inverter charger

2. check to see that new batteries are electrically connected properly and tightly at terminals

3. check for 120 v ac coming into charger

4. check for approx 13-14 v dc leaving charger

Knowing exactly which make model charger would help, after letting the group know your findings. All the best.

Can you post a picture of the battery wiring and hookups?

Was everything working prior to replacing the batteries?

What brand inverter /charger?

I would re- verify that the batteries are wired correctly.

Everything was working fine, until it wasn't.

I'm parked in a campground near Gettysburg, PA and it's 2200hrs. I take pictures tomorrow and do the recommend checks. Actually the house batteries died on the trip from Lazydays to Maryland, but I never pursued it at that time.

Not sure which converter/inverter you have, however when our Xantrex showed flashing lights, I cycled the unit thru the set-up steps, and the unit came back on line.

On my Magnum inverter remote panel, a flashing green light means standby.

The very first thing to do is meassure the house battery voltage while on shore power.
Should be 13.8 or more to indicate charging.
A fully charged battery will be 12.7v.
Check these items first instead of just guess in g.

Just out of curiosity does your control panel on your inverter/charger have a switch to turn charge on ?

Could be something so simple as you do not have charge mode selected.

First, your batteries are not (or should not) be supplying 12v to the coachr while plugged to shore power. The inverter/charger should be supplying that as long as it has 120v shore power available. Make sure the 120v input breaker for the inverter is on. Also check your inverter manual and verify what the slow green blink means. If your inverter remote panel is like mine (2004 Tradition), it has status lights for On, Charge, and Inverting.

What inverter/charger do you have?

Absolutly converter not convrting/charger not charging (Same device)

Three layouts
My RV: Converter #1 is a plug in device... Sometimes when I pull stuff out of the compartment where it lives I accidentally pull the plug. For some strange reason it does not work well (or at all) when unplugged. Under normal operating conditions I am most likely to figure it out long about 3AM....And its outside in a basement compartment so instead of getting dressed....

I enable converter #2, This is part of an INVERTER/Charger system and his hard wired in place so it can not be unplugged.. BUT it can be disabled.. Though it is also outside in a basement compartment the remote control switch is inside where I do not have to dress to enable.

(I will not go into why I do it this way here save to say I like #1's programming better).

The third kind of converter is intergrated into your power panel...Now it is hard wired so you can not unplug it but

All 3 of them have some things in common.
a: A circuit breaker (120 volt side) that can trip
b: Fuses (Reverse polarity fuses) that can blow or weaken with age and blow during normal bulk charging.

Home is where I park it!
