Question We recently had to replace both the engine and coach batteries on our RV. There is a button on the door for battery use or store. What is that button supposed to be on? We’re newbies to the big RV. Submitted via email Answer Welcome to the wonderful world of RVing! This switch is commonly called the Battery Disconnect Switch and is designed to disconnect your house batteries while being stored. Pushing it to the Storage side is like taking off the battery cable. It ensures that if you have left a light on in a compartment or anything inside, it will not drain your house batteries. Some RV manufacturers connect the LP Leak Detector directly to the battery bypassing the disconnect, so you may still have a draw even with the switch on Storage. To find out if this is the case with your rig, get a 12-volt test light, push the switch to Storage, then disconnect the negative terminal on one of the batteries. Touch the probe to the post and the alligator clip to the cable. If the light comes on, you have a draw.

Should be a simple video, am I doing something wrong? • Customer Service Over the past year we have been shooting content almost every month trying to get a wide variety of topics and cover the most frequently asked questions. Batteries, refrigerators, 120-volt electric, and general maintenance were the hot topics so they got priority. ![]() We do not have an actual video on the site of removing and replacing a toilet, however there is one in the Black & Gray Water Class. It’s a fairly easy procedure depending on the brand and model you have. Typically there is a cover flange around the base of the unit that is held together with a couple of screws. Remove that and you should see 4 nuts on the base that hold it in place. If you can provide the make, model, and year of the toilet I can get you a diagram. • tom RV Make: grand design, RV Model: momentom 349, RV Year: 17 battery won’t last more than 8 hrs with only fridg running [ 18 ft rv fridg ] is this normal or do I have something drawing power. Had fusion before and it would last much longer • Customer Service Hi, Tom. You could have something else running that will draw the batteries, however I suspect your batteries are not operating at maximum capacity due to sulfation? Lead acid batteries must be charge each month with a multi-stage charge that boils the acid with a high voltage charge during the bulk stage charge to break up the sulphur and then into a float and equalizing stage. Most converters do not have this capability unless you have a very expensive 2000 watt inverter or take the batteries out and use a professional multi-stage charger! Just leaving it plugged in does nothing more than topping them off and letting sulphur collect on the plates and limit the amount of energy storage. A sulfated batter will show a full 12.5 volt charge after charging, but will not last the intended amp hours so your refrigerator which probably only draws a few amps on the LP mode should last for a couple days, only last 8 hours. I would suggest getting the Battery Minder from Northern Tool which will send high impact waves to your battery and break up the sulfation and condition the battery. They claim to extend the battery “cycles” by 200 times which is 2-3 years longer life. But will be able to store more energy and provide longer power when dry camping. To check for any other drains on the battery, disconnect the refrigerator by pulling the 12-volt fuse and then take a multimeter set to DC voltage, disconnect the negative post of the house battery, place one probe on the terminal, the other on the empty battery post. If you see a reading, you have something that is drawing power. Usually it’s the LP leak detector or CO2. • Rand RV Make: Jayco, RV Model: Seneca, RV Year: 17 Issue: Power loss when not plugged into shore power. My house entry power steps and auto leveling system does not work on the house batteries when unit is not plugged into shore power. Lights and Winegard satelitte dish function. Low voltage indicator comes on and panel lights flash on the leveler system. Batteries show 12.5 volts on multimeter. Batteries are 3 months old could they be sulfated? I have a 2000 watt inverter that is left on always.
