Can a Bad RV Converter Drain a Battery?

Can a Bad RV Converter Drain a Battery?

You can get 120 volts of power by plugging the RV to a 20 or 45amp of its outlet panel that converts into 12 volts of DC power by the converter. 

Can a Bad RV Converter Drain a Battery? A bad RV converter drains a battery due to a poor circuit breaker, cooling fan, faulty resistor, and poor charging of the battery. For example, a cooling fan does not operate correctly, the lights are flickering abnormally, and the interior vents do not work well. You should test your RV converter and battery with the voltmeter to find the problem.

Recreational Vehicles are the most innovative solution to comfortable camping alongside any valley, beautiful river, lake, or hill resort.

These vehicles can equip with all luxuries that you enjoy in normal conditions at your home that are battery operated. 

It has a rechargeable battery with a proper converter station installed inside it. If it runs out of charge, connect your vehicle’s converter to all your appliances to use external power or another source at the desired voltage.

In other words, plug-in RV’s converter to convert all of its appliances to a different energy source. When you connect it to electrical items, spark produce takes little energy from your battery.

Furthermore, the converter uses the rest of the energy from an alternate source and keeps battery power intact from any drain. It can also be an inverter that converts direct current into alternate current.

In simple words, it converts one form of electricity from a battery or alternate source of power into other forms of energy. These can mostly keep with your camping vehicles or RV to rescue your battery. 

These converters are an integral part of your vehicle’s electrical system, which allows for efficient management of electrical appliances and power delivery without voltage fluctuations.

Under these circumstances, the device cannot be recharged, and its existing power will drain. 

Indications of a Bad RV converter

As discussed above, an RV converter keeps battery power intact and uses outside grid power to energize appliances inside your motorhome. Sometimes, it does not happen. 

It is due to any problem with your battery, poor connectivity, and the problem with your device.

In the case of a poor RV converter, the power supply from outside or an alternate source is cut off, and its power source starts losing its charge without even being in use. 

Furthermore, if your vehicle’s cooling fan or vents stop cooling or regulating temperature, you should check your converter first. It can happen mainly when your converter is not operational or facing some problem. 

Test the RV converter condition

If your motorhome converter is out of order or has doubt about its working condition, check some aspects.

By testing your DC batteries, check the battery’s consistent charge, around 12 to 13 volts.

First, you have to unplug the power sources and turn OFF the engine, inverter, and generator. Next, you use a multimeter to test its power capacity.

Test the AC power and converter if the voltage range is within acceptable limits; it is working well.

Why Does a Bad RV Converter Drain a Battery?

There are several reasons behind an RV converter that drain the battery. We have added common problems and easy methods to fix these issues.

A poor circuit breaker

Power supply from the converter to appliances goes always passes through a circuit breaker. 

A circuit breaker keeps devices safe from any abrupt fluctuation in the voltage of the electric supply.

Sometimes this circuit breaker faces problems due to which appliances face a Sharp rise or drop in voltage of the electric supply. Its efficiency can slow down due to issues in the breaker. 

RV lovers usually face the problem that their vehicle’s 40amp circuit breaker fails.

Sometimes wire terminal or the connecter tab can corrode or have an acid deposition. 

You can clean it with a home remedy like the appropriate water quantity and baking soda solution and dry it out for 8 to 15 minutes. 

In these cases, the converter cannot provide a continuous power supply from an outside source, so you’ll have to turn it on manually. The system is switched to battery power, resulting in power waste.

In this case, you should contact a qualified electrician to evaluate the problem, if necessary, replace the damaged components. 

You check the breaker panel on your circuit and turn on/off the breaker in a clockwise direction. 

Blown fuses

Another reason behind it can be blown fuses. If a high amount of current passes through the converter at a time, the fuse prevents damage and overloading by stopping the current flow. 

When the fuse blows out, it can affect its functioning. So you have to examine it properly, pull out by a plier, and replace it with a new one. 

You inspect throughout wires, having a low voltage that connects this device to the other electrical system. The optimal fuse for an RV is a 5, 10, or 30 amp fuse.

Damaged cooling fan

As the name indicates, these converter components prevent it from overheating. On the converter inside temperature basis, fan on/off periodically in normal working condition. 

The battery can drain when the inside temperature is high, so place the meter at the power line entrance point of the cooling fan to see the acceptable AC voltage.

If you need fan replacement, use the same model. If you use a different model, make sure it has the same current flow and voltage as the existing one. 

You ensure that area around that fan has proper ventilation. The absence of appropriate ventilation can lead to an inside airflow problem. In addition, debris deposition on the fan blade top can cause an issue.

Faulty resistors

The resistor in the motorhome converter regulates the electrical system and batteries voltage. 

If you observe the acid deposition in the connection points of the resistor gates, then the problem appears in the resistor that leads to drainage of the batteries. 

Its maintenance and replacement are difficult and costly, so consult an electrician because it necessitates disassembling the converter for easy access.

Check the battery voltage

You should check the battery is working well or not. Two vital factors in this can be storage and charging.

You can check it by charging it completely and disconnecting it from your RV so that it has no connection with its electrical system. 

This is because you cannot accurately determine power with an electrical connection.

So, you have to check its charging in the converter working condition and without its working. 

You should check that the battery shows more voltage in the converter working condition.

Use the best quality charger to charge ( not below 85%) and take good care in chilly weather because the liquid inside it can be affected. 

You should keep it inside at a stable temperature; disconnect it if you stop on the campsite.

Providing steady conditions like temperature and adequate charging is essential, but you can face issues if you fail to do so.  

In such situations, you should replace it with a new one because you cannot handle charging it for an extended period.
