Just a few days ago, my friend ran into quite a frustrating experience with his Revolt RV400. On his way home from work, he realized the bike’s headlights were not working.
You can imagine the inconvenience he must have felt. The ride back home is pitch-black due to early sunsets; without proper lights, one may even get stranded somewhere.
After a few minutes, he got to thinking about what he could do about this. He wanted to find out what was wrong with the lights. Eventually, he managed to troubleshoot the issues and get back on the road.
I am writing this article to share his experience of RV400 headlights not working with you, for it is very common to run into issues with your bike’s headlights.
1. Check the Headlight Bulbs
The first thing my friend checked while trying to fix Revolt RV400 headlight issue was the headlight bulbs because this is where the most common issues lie. The bulbs on his bike were unfortunately burnt out.
If you wish to check the bulbs of the electrical bike lighting system, begin with a visual inspection. You can tell if the bulb is burnt out or not from the blackened filament inside. Replacing a bulb after this is simple. All you need to do is turn off your RV400, like my friend did, and let it cool down.
Now, remove the LED headlight housing carefully before taking out the burnt bulb. You can now put the new bulb in place, but ensure it is compatible with the RV400.
You can start the bike to test the bulbs. My friend did the right thing by replacing the bulb. Now, he wanted to get to the core of the issue.
2. Inspect the Wiring and Connections
My friend did not stop inspecting the bike even after replacing the bulb to get to the core of the Revolt RV400 lighting issues.
He realized that damaged wires also damaged headlights in the long run. He took a closer look into the wiring that connects the headlights to the main electrical system.
What you are looking for here are loose or damaged wires. My friend found a slightly frayed wire from the power supply that could have added to the damaged headlights.
As soon as you see a problematic wire that is broken, frayed, or loose, focus on fixing it first before turning on the bike again.
Loose wires are often fixed easily with electrical tape or a wire connector. If you see loose connections, those can also be fixed through a small wrench/ pliers.
By fixing the wiring harness, my friend ensured that his new pair of bulbs would serve him for a long time without issues.
3. Examine the Fuse Box
My friend got to examine the headlight fuse box once he realized the bulb and the wiring were all right. The fuse can often be the underlying issue.
The fuse is an important part of the electrical system. Once blown, the headlight will not work at all. To check it, find the fuse box on your RV400. If you feel lost, refer to the user manual to accurately pinpoint this box.
Now you can see if the fuse connected to the headlights is intact or is damaged (burnt/ broken). In case it is damaged, find a fuse with the original rating for replacement.
My friend found a blown fuse in the box, which added to the RV400 LED headlights problem; this prompted him to replace it as soon as possible.
4. Test the Headlight Switch
Even with all set, my friend noticed a few flickers in the RV400 headlight while it is on. Everything is reconnected but it turns out that the headlight switch can sometimes be the problem. Faulty switches cause malfunctions and flickering.
To check if your switch is the problem, turn it on first. What can happen is that the lights do not turn on at all, or they flicker when they do. Grab a multimeter to check the continuity of the switch.
If you do not know how to use a multimeter, consider watching an online tutorial beforehand. In case the multimeter indicates a fault, get your switch replaced. Fortunately for my friend, the headlight switch was not an issue, and the lights worked fine after he had turned them on after a while.
5. Consult the User Manual
Consulting the user manual shall never be overlooked, especially by those who do not understand bike repairs.
My friend does not perform repairs at will but rather uses the user manual to recommend techniques. The RV400 fortunately has a comprehensive user manual to help with electrical system troubleshooting.
The manual contains all the information you need about this bike model, fuses, switches, and other electrical components.
If you are not at all capable of performing repairs, call in professional help from authorized Revolt Motors technicians instead. In case of complex electrical issues, this is the only option.
