RVs use both 12V DC (battery) and 120V AC (shore power) systems. Converters, inverters, breakers, and wiring take a beating from vibration and use. When lights flicker, outlets die, or the battery won’t charge, a qualified RV electrician can diagnose and repair the problem so you stay powered on the road.
Common RV Electrical Problems
Converter and Charger Issues
The converter turns 120V shore power into 12V DC and charges the battery. When it fails, 12V lights and appliances stop working and the battery may not charge. Symptoms include dim or dead 12V circuits and a battery that never seems full.
Inverter Problems
- No 120V when off grid — Inverter may be off, tripped, or failed
- Low voltage or shutdown under load — Weak batteries or undersized inverter
- Alarm or error codes — Overload, overheating, or internal fault
Shore Power and Outlets
GFCI outlets trip, breakers flip, or one leg of 50-amp service goes dead. Often caused by a bad cord, pedestal wiring, or internal breaker panel or connection issues. An electrician can test shore power and trace faults through the panel and outlets.
12V Lighting and Wiring
Lights that flicker, don’t turn on, or work only sometimes usually point to loose connections, corroded grounds, or failing switches. Older rigs may have brittle or damaged wiring that needs repair or replacement.

Maintenance Tips
- Check battery connections and water levels regularly
- Test GFCI outlets and breakers periodically
- Inspect shore cord and inlet for damage before plugging in
- Avoid overloading circuits; know your amp rating
- Have converter and inverter checked if 12V or 120V acts up
