LP/CO Detector question by newbie

Hi folks,

I'm new to the RV community, having just bought my first motorhome, a 2008 Georgetown 350TS. The problem I'm having is that the CO/LP detector started chirping while the RV was sitting in my back yard with the gas off. When I turn on the engine for a while, the chirping stops. I've read several posts through Google, and everyone refers to the possibility of the "RV battery" being low or possibly need replacing. When you talk about the "RV battery," does that mean the battery at the engine compartment that versus the "house" batteries? The RV starts right up, so I wonder if the battery up front is bad, but I haven't done any voltage testing. Sorry for the dumb question. I'm just picking up the lingo.

No such thing as "dumb" question. Coach battery (s) usually under the steps. Chassis battery under hood. Chassis is high current starting battery. The coach battery is long lasting Deep cycle. Totally different purposes. Have battery tested before changing.

The alarm is probably going off because the coach batteries are low and when you turn the switch on, it connects the batteries used for starting which have a higher charge. Once you start the engine, the coach batteries also get charged.

Still don't know which is the "RV battery." I'm trying to figure out which battery powers the LP/CO detector.

I think I understand now. The coach batteries power the LP/CO detector. Thanks, folks! I guess I'm buying some new batteries......

In Georgetowns I've seen you remove inside steps to access.

You most likely don't need new batteries; just charge up the ones you have.

X2. As VinceU said, get them tested first. Your local auto parts store can do that. Also, check the water level.

On my 2004 GT all of the batteries are under the step.

Good luck.

Batteries need a good charge on them (if they will take a charge) before they can be tested properly, charge them up good before taking them in for testing or the person testing them may charge them for you if you don't have a charger (don't let anyone sell you new batteries without charging yours before testing). It is very normal for the coach batteries to go down when not in use for a while so you need a battery tender to keep them charged when not using the RV or plug into shore power an your RV's converter will take care of it (I'm pretty sure the Georgetown will have a 3 stage converter so you won't overcharge the batteries).

Thanks, all. I've had the RV plugged into 15 amps at my house for the past two weeks. The beeping continues until I actually start the vehicle and let it run for about 10-15 minutes. I'm wondering now if I also need a new converter/charger since the coach batteries aren't holding a charge.
