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.

Is it good to keep your RV battery charged all the time?

While you can certainly keep your RV plugged in all the time, doing so can drain your wet-cell batteries’ water levels more quickly, so be sure you’re checking them often if you camp this way. And remember, letting your batteries get too low in charge is bad for their overall lifespan, so try to keep them charged on a regular basis. 6.

What does it mean to have battery bank in RV?

No, there is no financial establishment for batteries; a battery bank is what you get when you join two or more batteries together. This increases voltage or amps when you need more power. Joining RV batteries in series allows you to keep the same amperage but adds extra voltage.

Why does my RV battery not hold juice?

We received a question from an RV Repair Club member asking why their RV battery wasn’t holding any juice after a full charging cycle. While the problem of an RV battery not charging typically stems back to one common issue, there are a handful of other possibilities.

What should I do if my coach battery is not charging?

The first item I would look at is the alternator. Start the coach and run it at around 1500 Rpm’s and the battery voltage should rise over 14 volts and then should drop down as Rpm’s are decreased, inspect the alternator belt make sure it is snug and not slipping.

How are batteries maintained in a motor coach?

In asking around, we have found that many savvy owners, not only of motor coaches, but of all sorts of other equipment that depends upon wet cell batteries for power, use this clever system to maintain the proper level of electrolyte in their batteries. Chapter Three – The “Other” Battery Under The Hood; The Chassis Battery

What makes a coach battery distort so much?

They are stamped out of sheet metal, and as such they distort easily. When Chinook built our coach, they loosened the setscrew on the positive cable clamp and inserted a secondary lead that goes to the Battery Isolator (the “Smart Switch”). In tightening the clamp when they reinstalled it, it distorted and failed to make a solid connection.

What is the solenoid on a coach battery?

Yesterday I was able to look at the Solenoid (I believe it is a solenoid and not an Isolator) in the battery compartment. It seems there was another “Solenoid” daisy chained to this one and the positive cable that connects to the battery was in the middle.

What should I do if my RV battery is not charging?

Most of the time you will need to replace the problematic battery. You will need to replace the batteries with a new one or reconditioned 12-Volt RV batteries. Though if you have the time on your hands, you might be able to find a battery technician who can recondition your batteries for a minimal charge.

Why does my RV battery keep going dead?

This mistake is periodically made by new RV owners and those who store batteries for infrequent usage. The battery is going to slowly discharge its power over time. It will, eventually, go dead. A low level of power from a trickle charger can prevent this, though it may not fully charge the battery.

Can a 12 volt problem cause a refrigerator to fail?

A 12-volt problem can cause failure of other appliances and systems if they have 12-volt power to their controls. The refrigerator and air conditioner, even running in propane-fueled mode or on AC power, require DC voltage for their logic circuits, and so may fail to operate when there is a DC system problem.

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.

What are the battery levels on a coach RV?

The batteries not running are all 12.58 The Chassis battery running is 14.35 The Coach batteries running stay at 12.58 Plugged in not running the Batteries are at 12.58 I checked all fuses and breakers and everything is ok not tripped or blown.

Why is the battery on my ALINEr not charging?

There will be a slight draw on the batteries from the radio presets and engine CPU for the engine battery, and a draw from the LP leak detector so it’s good to isolate those. My battery on my aliner is not charging after I drive with it all connected to my destination. The battery itself was tested and is chargeable.

Why does my RV battery not charge when I plug it in?

And depending on the charge that has depleted from the battery, this can take a long time. But there are cases when there might be a problem with your power source, converter or battery and your RV battery actually does not charge. So how can you know when it is not charging?

Why is the battery on my RV not charging?

If you check the batteries with a multimeter or voltage meter an hour later, they should still give you the same fully charged reading. If the voltage numbers are going down, then it’s likely a battery problem. Most of the time you will need to replace the problematic battery.

What happens if my battery dies on my camper?

The breaker panel will hook up to all of your AC outlets while the battery will hookup to any DC appliances. If your battery were to completely die, you could still run all of your appliances off of AC outlets with the exception of the DC only appliances.

Why does my RV battery keep dying at low charge?

But when a battery stays at a low charge (below 12.5 volts) for a long time, the crystals get too large to break down and the battery is busted–who knew? Charge your battery fully and frequently, and never let it drain below 50%. Your RV battery is 64% water.

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.

What happens to the crystals in a RV battery?

The crystals disappear when the battery’s charged. But when a battery stays at a low charge (below 12.5 volts) for a long time, the crystals get too large to break down and the battery is busted–who knew? Charge your battery fully and frequently, and never let it drain below 50%. Your RV battery is 64% water.

Why does RV battery die when plugged into shore power?

RV chassis battery dies when RV plugged into shore power. Why? – YouTube RV chassis battery dies when RV plugged into shore power. Why? If playback doesn’t begin shortly, try restarting your device.

What happens to batteries when plugged in to shore power?

When plugged into shore power at the campground, presumably the AC to DC converter will charge the auxiliary battery bank. All the lamps, fans, water pump, etc., still operate on 12-volts DC, just that the DC electricity is provided by the converter instead of the batteries while plugged in.

How to fix a parasitic drain on the battery?

A failed diode in the alternator creates a closed circuit that drains your battery even when the engine is off. If you’re too busy during the workweek and can’t get to it until you’re off, some short term fixes are to disconnect the battery at night, and carry a portable jump starter in your vehicle.

What should my parasitic power draw be on my car?

Power draw should be under 50 milliamps. This will display as 0.05 amps. If it’s higher, that is your parasitic power draw. Well under 50 milliamps, and you’ll need to be shopping for a battery.

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?!

What does it mean when your car battery is dead overnight?

You go out to your car and the battery is dead overnight, this can be frustrating to say the least especially when you are late to work or got the kids ready for school and ready to leave. When the battery looses its charge in the morning you could have a voltage drain in the electrical system which is called a parasitic draw.

Is it bad to run a battery below 70%?

Go lower than that and your deep cycle battery lifespan drops even further. Ideally then, you don’t run your battery below 70% state of charge, but this is impractical. If you had a 200 amp hour battery system, you could only use 60 amp hours, which is ridiculous.

Why does my battery die when I Turn Off the fridge?

Fridges, and many more. While each draws a small charge, they can completely kill a battery when combined. Picking up a battery disconnect switch to stop chronic drain for good. Whenever you use a lead battery, small crystals of sulfuric acid start forming on the metal plates inside. The crystals disappear when the battery’s charged.

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 do I need to clean my coach battery?

However, the battery cables for both the chassis and coach batteries must be cleaned. A good steel wire brush and top post battery cleaner are really all that’s needed. Turn off all your battery Main Switches, disconnect from shore power, have your generator off and go to it.

What causes a car battery to drain while driving?

Faulty Charging. If your charging system isn’t working properly, your car battery can drain even while you’re driving. Many cars power their lights, radio, and other systems from the alternator, which can make the battery drain worse if there’s a charging problem.

How long does it take for a deep cycle battery to charge?

When the battery receives half to two thirds of the power you think it does, it will die sooner than you expected. Another mistake is not letting the batteries charge long enough. They typically need eight to ten hours to charge the battery. A fully discharged deep cycle battery may need twelve hours of charging when connected to the power grid.

Why is my RV battery draining so fast?

Why might your RV battery be draining too fast? You may have more power draw on the batteries than you think you do. Dome lights and headlights left on are two common culprits.

What happens when you disconnect the battery in an RV?

Picking up a battery disconnect switch to stop chronic drain for good. Whenever you use a lead battery, small crystals of sulfuric acid start forming on the metal plates inside. The crystals disappear when the battery’s charged.

Where did the batteries for the coach come from?

Of course, it was too late to save our original coach batteries, so on our way south to the Annual Rally just before Labor Day 2005, we stopped in at the Interstate Battery dealer in Portland and “ponyed up” for four new house batteries.

How often should I replace my RV battery?

They power kitchen appliances, lights and more when the RV isn’t running. A well-made deep cycle battery will last far longer than a starter battery — up to three or four times as long, in fact — meaning you shouldn’t have to replace one very often.

What are the battery terminals on a Ford coach?

The clamps on the chassis battery terminals in our coach are Ford OEM clamps. They are stamped out of sheet metal, and as such they distort easily. When Chinook built our coach, they loosened the setscrew on the positive cable clamp and inserted a secondary lead that goes to the Battery Isolator (the “Smart Switch”).

Why does my coach battery keep going dead?

Brett, if this member is having both the house and the coach batteries going dead, it seems there has to be some sort of drag on them and his inverter is not keeping up or not working. If there is something dragging down both batteries down he might also have a bad isolator. The only thing on should be the radio/clock.

How do you charge batteries in a coach?

And some coaches have both battery banks wired so they are charged by the inverter/charger, others are wired so that only the house batteries are charged by the inverter/charger. If the latter, you will need a trick l start, Echo charger, etc to charge the chassis batteries.

Can a lead acid battery be replaced in an RV?

Basically, they don’t recharge as well as flooded lead acid batteries. The process to recharge is much slower, and if they are overcharged, it can cause permanent damage to the battery’s cells. However, gel type batteries are being largely replaced by another kind of VRLA incorporating a fiber glass Absorbed Glass Mat (AGM).
