![]() ![]() If you have a fully charged battery and check it again after a few hours of use, it should still have a full charge. The reading at the battery should be approximately 12.7 volts. If you have a bad battery that is no longer holding a charge, this can present itself as an issue with your power converter. The converter’s job is to keep the RV batteries fully charged and lessen the drain of power from them. The breakers, fuses, and in many cases the power converter, will all be located together. The power converter itself will also have a few fuses that should be checked.Ī wiring issue such as a short or bad ground will likely result in a blown fuse or a tripped breaker. If you don’t have either of these tools, you can simply pull the fuse and visually see if it has blown.Ĭheck the fuses for any items that are not working. Fuses and breakersįuses are easy to check with a test light by touching both sides of the fuse and checking for power or using a multimeter to check for power. This would likely lead to a converter issue.īefore assuming your converter needs to be replaced, check the cheap, easy-to-fix things that may be causing issues commonly associated with a bad RV power converter. If they are on but your lights are not working, then there is power to the RV but nothing is converting to 12 volt DC. These appliances run on 110 volt AC power. This translates to a DC voltage reading at the batteries of 11 to 13 volts.Īn easy way to isolate the power converter from a bigger electrical issue is to plug your RV into shore power and check your microwave or TV. When your RV’s converter is working properly, it should have an AC voltage reading between 110 to 130 volts. Signs of a faulty power converterĪ faulty RV power converter will most often show itself as dimming or flickering lights, or the loss of use of 12 volt powered items such as electrical outlets, lights, refrigerator, or low battery charge. This is the opposite of the RV’s power inverter which changes DC power from the batteries into AC power. The power converter’s job is changing the current from AC to DC along with keeping the RV batteries fully charged. Your RV batteries provide 12-volt DC power but are limited to how long they can provide that power before the charge drops. However, many things including lights, outlets, and appliances require 12 volt DC power. Some things in your RV such as your air conditioner require AC power. When plugged into shore power at a campground or running off a generator, your RV is supplied with 110 volt AC power. What is the purpose of an RV power converter? Hidden away in cabinetry or under a seat, the power converter often goes unnoticed and many people don’t even know what it does. Without it, power will be limited and ultimately the function of your RV will be minimal. Your RV power converter is the brains of your RV.
