It could be the onboard charger itself, a relay/solenoid, a wiring problem into or out of the charger or perhaps an inline fuse. You could try to look for loose connections or a blown fuse. It is worth a call to the RV manufacturer to see if they can help you troubleshoot and resolve the problem yourself.

Just so, does RV battery charge when plugged in?

Whenever the RV is plugged in the coach battery is being charged. It's really just a trickle charge, but over time it can deplete the electrolyte levels in the battery cells. You need to check, or have somebody check the battery at least monthly when the RV is plugged in during storage.

Secondly, is it OK to leave your RV plugged in all the time? Yes, you can keep your Travel Trailer plugged in all of the time. One of the things you need to monitor is the house batteries for the trailer. You should check the electrolyte levels on your batteries at least once a month to make sure that they are not low or have gone dry.

Also Know, why won't my RV battery hold a charge?

Just because everything is off doesn't mean it doesn't consume some form of wattage. Charge the batteries as they naturally discharge. Unregulated solar panels may fail to maintain a charge — or, even worse, boil off electrolyte. Converters should also not be left plugged in so as to charge the RV battery.

Can you overcharge an RV battery?

And remember as soon as the battery state-of-charge drops below 12.5 volts sulfation starts, and if the battery stays in that condition for an extended period of time the battery will die. It's a vicious cycle! Next on the list is overcharging the battery. Your RV has a converter with a built-in battery charger.

Should I disconnect my RV battery when plugged in?

The disconnect should be turned off when you store your camper so your batteries discharge more slowly. Doing that when you are plugged into shore power also disconnects your batteries from the charging circuit of your power, meaning that even if the rig is plugged into shore power, your batteries will not charge.

How long do I need to run a generator to charge RV batteries?

2 hours

How do I know if my RV converter is bad?

When Your Converter Goes Bad To tell if your RV converter is bad, you will start to see warning signs. Your interior lights are the easiest indicator. If you are seeing your lights dimming, your converter could be in trouble. Other clues would be your electronic devices do not work as well.

Why does my RV battery keep dying?

It has too much charge (seriously) Your RV battery is 64% water. When it's overcharged, the water boils off and the rest of the battery components fry. Some older (or cheaper) converter chargers aren't equipped with a shut-off that stops overcharging.

What charges my RV battery?

Alternator. One of the most popular ways of charging a 12-volt battery is by using a vehicle's alternator. This is how vehicles charge their own 12-volt batteries and it is often how motorhome house batteries are charged. An alternator works by converting mechanical energy into electrical energy.

How does battery disconnect switch work on RV?

The battery disconnect switch for RV cuts off the electrical power between your batteries and the RV. Flipping the switch helps protect against electrical fires and theft when your RV equipment isn't being used. It's also important to shut off the power as a safety measure when you're doing maintenance.

How do I test my RV converter?

How to Test a RV Converter Charger

Use your voltage meter to test across the 120 volt AC terminals to determine whether or not power is being sent to the converter charger.

Use your volt meter to test across the coach battery terminals.

Determine whether your converter charger has separate outputs to the vehicle's 12-volt systems and to the charger.

How do I charge my motorhome battery while driving?

Ways of Charging an RV Battery While Driving

Combine the batteries using high amperage and good quality cables for reducing the voltage drop.

The VCR disconnects and parallels the start and auxiliary batteries automatically.

Does a 7 pin trailer plug charge battery?

You can put a maintenance charge on your trailer battery with the 12 volt accessory circuit of the 7-way. The 1:00 position of your 7-way carries this circuit. You would just need to run a length of 10 gauge wire like part # 10-1-1 (sold by the foot), from this pin to the positive terminal of the battery.

Will an RV converter work without a battery?

Most things inside your RV will not work without a properly functioning 12-volt DC house battery system. Think of the converter as the main 12-volt DC power system along with the house batteries, and that these batteries actually function as your backup, or the piggy bank if you will.

What does a converter do in a camper?

When you plug your RV into an electrical source, or when you use the onboard generator, the converters job is to reduce 120 volts AC down to 12 volt DC to supply power to all of the 12 volt appliances and accessories in the RV.

Does my RV have an inverter or converter?

Why You May Also Need An RV Inverter An RV inverter converts 12 volts DC from the battery into 120 volts AC. An inverter is the only way to run AC appliances in your RV without being connected to shore power. Keep in mind that the inverter still only allows you to use as much power as is stored in your battery.
