Battery problem

Here's the scenario.......When we stopped our Journey '08, the house battery immediately dropped to 10.2. The refrigerator was blinking "low dc". Were told the batteries needed replacement which was done. It is still acting up occasionally with the new batteries. When driving we also are hearing a chirping sound....thought it was the smoke alarms so we took them down to see if they were the culprit. Not so....still an occasional chirp almost like the sound when the propane is being turned off and on. Any Ideas?????

The curping may be from your LP gas detector. It is set to give off an audiable chirp just like that when battery poweer is low. as for you batteries they may not getting the proper charge, check your conections at batery terminals, you may have a short somewherre finaly if that dont work get you converter chager checked, it may be malfunctioning.

The chirping is indeed like when the propane is turned on and off (you do so with a switch right) it is he Explosive Gas (Propane) Detector saying "FEED ME FEED ME (Electricity that is) or Low battery.

As to why you are still seeing low battery I don't know. I have heard of cases where a dealer messed up an install, but this is stuff I get into hands on.

Here is what I do.

Start with a handy dandy volt meter. Measure the voltage across the batteries.. Choose the terminals that run off into the coach, not wires that hook battery to battery.

Question: Did you install six volt pairs of 12 volt batteries?

Don't know.. Look at (photograph) the top of the batteries and i'll tell you.
Home is where I park it!

Did they check to see that the coach batteries were getting charging voltage from the engine alternator? (14.1VDC supplied via isolation relay on a Winnebago product) Then, did they verify the batteries are getting charging voltage from either (or both) shore power or generator? (most likely a inverter/charger or possibly a converter/charger).

Whether done as part of bad battery troubleshooting or new battery confirmation, all this should be done for a proper installation.

How long does it take to kill batteries? Do you have a inverter and is it on?

Sounds to me as if there is a problem with your charge relay and /or the converter. Time pull out the volt meter and check output to the batteries while traveling and on shore power. Battery voltage plugged in or engine on should read above 13.5 volts. A fully charged battery that's in good shape should read 12.8 volts with nothing plugged in and no power draw; anything below that not plugged in or engine running is considered in need of a charge. Engine alternator provides power for batteries running and converter provides power when plugged in. Typically in the range of 13.8- 14.4 volts.if there is no voltage that high on shore power you have a problem somwhere.

Hi cfing,

Consider posting this questions in the Winnebaggo Owner's forum. On the main iRV2 page scroll down until you see the forum. There are many unique things from one manufacturer to another. Nobody knows your coach like another member who has one just like yours.

Need more info about your rig, Do you have a full size fridge, ie 120vac type? If so then check inverter. Check normal charge circuit also. Does it do OK when generator is running, on shore power? More info I say more info is good.

I recently went through the same situation with my unit. Long story short after removing converter/inverter, bench testing, battery testing, remote control testing, it turned out that some of the battery cables were not making good connection. Removed each cable from post, lightly sanded and reconnected and that cured the problem. I should have thought of the simple problem before jumping to the complex ones. The chirping was the control box for my electric awnings reading less than 12 volts. Disconnected the power to that unit and it stopped.
