Why are the batteries on my coach going dead?

Why are the batteries on my coach going dead?

The engine alternator was simply providing the DC voltage while the engine was running. Regardless of the brand of motorhome, the brand and type of converter/charger installed and whether or not any disconnect devices are employed, it’s obvious the batteries are not receiving a charge while the coach is plugged in to shore power.

Where does the 12 volt DC power come from?

All of the 12 Volt DC power for the water pump, furnace, refrigerator, etc. comes from the special “house batteries”. To keep them full, charged and ready to supply 12 Volt DC power within your RV, the “converter” will be used to convert those shore power 120 Volts of AC to 12 Volt DC.

Can a 120 volt AC be used in an RV?

Now, since your stick and brick house has only 120 Volt AC, we immediately know an RV is “different” – therefore, the RV Electricity systems within an RV should only be worked on by someone “qualified” to do so ! What Powers What? RV Parks and Campgrounds only supply 120 Volt AC. So, how do you get the 12 Volt DC??

What does it mean when your RV battery goes dead?

The fact that the lights got brighter when you started the engine is an indication that the batteries are indeed very low, if not completely dead. The engine alternator was simply providing the DC voltage while the engine was running.

When to jump start a car with a dead battery?

A dead battery never seems to occur when you have nothing to do and are surrounded by family and friends who are ready and able to jump start your car for you. A dead battery occurs when you are away from home, totally alone, or in a major hurry to go somewhere, like work.

Why does my battery go dead when plugged in?

If the voltage does not go up when plugged in, look for a blown fuse in the charge circuit in the converter/charger. Look also for any electronic disconnect switches that totally isolate the battery system. It’s common on some coaches to employ these during storage or a lengthy downtime.

What causes a car battery to go dead?

One of the most common causes of a dead battery is a slow and sneaky drain of the battery’s charge. A number of culprits may be at fault for a drained battery and it can occur with both the chassis and house battery. Some chassis battery drains include: Headlights left on; Exterior lights; Engine left in auxiliary mode; Front audio systems

What’s the deal with the battery disconnect switch?

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.

Why does my coach battery go dead when plugged in?

If you can measure an increase in DC voltage at the battery bank when the coach is plugged in, then the battery charge circuit is at least complete and probably working. If the voltage does not go up when plugged in, look for a blown fuse in the charge circuit in the converter/charger.

Can a coach battery be used in an RV?

As a safety on many RV vehicles, there is a switch on the dash that will allow the RV’er to combine the chassis and coach battery power while tying to start the engine or the generator. This should be done only in an emergency – and carefully!

Is the chassis battery the same as the coach battery?

The chassis battery and the coach battery are 2 separate battery systems – except they both will get charged by a common method. All chassis battery systems are based on a single 12 volt battery – that will allow high amperage draw (especially if a diesel).

Can a deep cycle battery be mounted on a coach?

AGM – Absorption Glass Mat batteries are quickly taking over the “coach” side of RV batteries – with good reason! AGM Batteries are completely sealed, deep cycle, do not have any fumes and can be mounted in any position needed! Pretty Cool, huh?!

How many coach batteries does a Roadtrek sprinter have?

It turns out that the current Roadtrek models of 190 and 210 and the Sprinter models have two coach batteries. I have been told by owners that not all of the older models do and many have just one.

Why does my allstays RV have a dead battery?

We have found in a AllStays.com RV that this isn’t always complete because something like the steps or a cab stereo may be wired to the chassis or engine battery. So even though you turned off the “kill switch” and think everything is fine, you come out to a dead engine battery.

Can a diesel coach have an emergency battery?

YES, most diesel coaches have a battery boost/battery combine/emergency start switch just like most gas coaches do. They serve to combine the CHASSIS to the HOUSE battery bank. They can be combined to bring the battery with more charge to bear whatever you are trying to start– main engine or generator.
