Use a 2-prong automotive flasher to make camper lights flash

Upgrading your camper lights to LEDs can cause them to malfunction, either by not flashing at all or hyperflashing (flashing faster than normal). This is because LEDs draw very little power, which can be insufficient to make a thermal flasher function properly.

You can fix this issue by using a 2-prong automotive flasher. This is a simple plug-and-play solution that requires no resistors and works without the need for a ground wire.

To install a 2-prong automotive flasher, first locate your camper's existing flasher. This is usually located near the battery or the fuse box. Once you've found it, simply unplug the old flasher and plug in the new 2-prong flasher. You may need to attach a ground wire to the new flasher; this can usually be connected to the negative battery post or the vehicle's sheet metal.

With the new flasher installed, your camper lights should now flash at a steady rate. This solution is compatible with both LED and incandescent bulbs, so you don't need to worry about which type you're using.

It's important to be a considerate neighbour when using your camper lights at night. Always turn off your lights before bed, and avoid leaving them on all night if you're camping in a natural setting like a state or national park.

Check for loose wires

Checking for loose wires is an important step in ensuring the proper functioning of your camper lights. Here are some detailed instructions to guide you through the process:

Step 1: Identify the Problem

First, you need to determine if the issue is indeed caused by loose wires. Start by observing if any of the running light bulbs are not working. This could be an indication that the wires connecting the lights to the electrical system may have loosened.

Step 2: Inspect the Wires and Connections

Next, carefully inspect the wires and connections associated with the camper lights. Look for any signs of looseness or damage. Vibrations from driving on uneven terrain can cause the wires to become loose over time.

Step 3: Secure the Wires

If you notice any loose wires, use appropriate tools and techniques to secure them. This may involve tightening connections, soldering joints, or using wire connectors to ensure a firm connection.

Step 4: Test the Lights

After securing the wires, test the camper lights to see if they are now functioning properly. Turn on the lights and observe if they illuminate as expected. If the problem persists, move on to the next step.

Step 5: Check the Fuse

Another potential issue related to loose wires is a blown fuse. The fuse associated with the camper lights may have burned out due to a loose connection. Check the fuse box and inspect the fuse for the camper lights. If it appears burnt or damaged, replace it with a new fuse of the same type and amperage.

Step 6: Inspect the Grounding Wire

If the problem continues, the grounding wire may be at fault. Vibrations from driving can sometimes cause the grounding wire to become dislodged or faulty. Inspect the grounding wire to ensure it is still securely connected to the frame of your camper and is free from corrosion or damage.

Step 7: Consult a Professional

If you have checked for loose wires and performed the above steps without success, it may be time to consult a professional electrician or RV technician. They will have the expertise to diagnose and resolve more complex issues with your camper lights.

Remember to practice safe driving habits and ensure your camper lights are in optimal working condition before embarking on your next adventure.

Check for a bad battery

Checking for a bad battery is a crucial step in maintaining your camper's lights and electrical system. Here are some detailed instructions to help you determine if your camper's battery needs replacement:

Age of the Battery:

Firstly, consider the age of your battery. Camper batteries typically last between three to six years, or even longer with proper care and maintenance. If your battery is older than five years and exhibiting issues, it's probably time for a replacement.

Check for Corrosion:

Corrosion on the battery terminals or cables is a significant red flag. It indicates unwanted chemical reactions and can hinder the battery's ability to charge and discharge efficiently. Corrosion is a leading cause of early battery failure, so keep an eye out for any white or bluish powder on the terminals.

Physical Damage:

Inspect the battery case for any signs of physical damage, such as cracks or leaks. If you notice any damage, it's a clear indication that your battery is failing or has already failed.

Reduced Battery Capacity:

If you find yourself having to recharge the battery more frequently, it may be a sign of reduced battery capacity. Observe if the battery is holding a charge as well as it used to. If it isn't, it might be time to invest in a new one.

Difficulty Holding a Charge:

Pay attention to how your battery performs after charging. If it struggles to hold a charge and you notice a decline in performance, it could indicate deteriorating internal components, which is a sign that it's time for a replacement.

Difficulty Starting:

If you experience difficulty starting your camper's engine or notice a slow engine start, it could be due to a weakening battery. This is more noticeable if you have a starting/cranking battery specifically for engine ignition.

Electrical System Problems:

If you observe that your camper's appliances, lights, or radio aren't functioning properly, or if the lights flicker, it may be a sign that the battery is struggling to provide consistent power.

Low Voltage:

Check the voltage of your battery using a multimeter. A fully charged 12-volt battery should read around 12.6 to 12.7 volts. If the reading is lower than this range, your battery may be failing, and it's time to consider a replacement.

Uneven Charging (for multiple batteries):

If your camper has multiple batteries, keep an eye on their charging patterns. If one battery is charging unevenly compared to the others, it could indicate an issue with that specific battery.

Store and Maintain Properly:

When storing your camper for extended periods, ensure the battery is stored in optimal conditions. Store it in a cool, dry place with temperatures around 60-70 degrees Fahrenheit. Additionally, consider using a battery maintainer to keep the battery at the optimal charge level during storage.

By regularly checking for these signs and performing proper maintenance, you can ensure your camper's battery remains in good condition and extend its lifespan.

Check for loose prongs in the plug

If your camper lights are flickering, it's likely that the source of the problem is electrical. One of the go-to sources is your converter—flickering lights can be a sign that your converter is failing and needs to be replaced. However, it could also be a loose connection.

If your 120-volt lights are flickering, start by checking the plug at the pedestal. If any of the prongs in the plug are loose, this can cause the problem. Try tightening the prongs or replacing the plug or extension cord. If the connection is good and all prongs are tight, then the problem could be inside your RV or trailer, or with the pedestal. In this case, you may need to call an electrician.

If you're experiencing flickering lights in your trailer, it could be due to a bad ground. Check the white wire from the plug and ensure it is properly attached to the frame, usually near the coupler. If the trailer is on a tilt bed, a ground wire needs to be run directly to the trailer light attachment bolts from the plug.

Check for a failing converter

If you're experiencing electrical issues with your camper van, it could be due to a failing converter. The converter is a crucial component in the electrical system, converting 120-volt alternating current (AC) power to 12-volt direct current (DC) power. So, if your converter is bad, it can cause all sorts of electrical problems. Here are some signs that your camper van's converter may be failing:

  • Dead battery or no power: If you enter your camper van and the 12v lights, water pump, or 12v accessories won't turn on when plugged in, it could be due to a faulty converter.
  • Dimmed or flickering interior lights: If your interior lights seem dim, it usually indicates low DC voltage. This issue should be resolved by plugging your camper van into shore or generator power. If the problem persists, it may be due to a faulty converter.
  • Flickering lights can also be caused by quick voltage changes, which can result from low batteries, inconsistent output voltage, or improper grounding. As the converter functions as a power supply and charger, sudden voltage drops could suggest that it's struggling to maintain continuous output.
  • Slow-spinning fans: If your vent fan, over-the-stove exhaust fan, or DC power ceiling fans are spinning slower than usual, this could indicate low DC voltage. If the issue doesn't resolve when plugged into shore power, it may be due to a faulty converter.
  • Unusual noise: A strange humming or buzzing noise from the converter could be a sign of a simple issue like a dirty fan, or it could indicate that other internal parts are failing.
  • Overheating: Most converters have internal fans to keep them cool. If you notice that the fan isn't turning on and the converter is hot to the touch, it could indicate a failed fan, which may cause the converter to overheat and shut down, leading to inconsistent power output.

If you suspect that your camper van's converter is failing, it's important to perform some diagnostic tests to confirm the issue. You can use a digital multimeter and a one-handed circuit tester (test light) to check the converter and identify any problems. Remember to exercise caution when working with electrical systems, and if you're unsure, consult a professional RV technician.
