RV electrical diagnosis and repair.
RV electrical problems can cross between the battery, converter, shore-power and appliance systems. Test the cause before replacing parts.
12-volt and 120-volt systems
Trace the failure logically.
A dead light, tripped outlet or weak battery may be the symptom of a larger connection, charging or power-source issue. Mobile diagnosis keeps the RV in the conditions where the problem occurs.
- Battery and charging-system concerns
- Converter diagnosis
- Interior and exterior lighting
- Outlets, breakers and GFCI problems
- Shore-power and power-distribution concerns
Safety first
Do not ignore heat or burning odors.
If you notice smoke, sparking, melted wiring, unusual heat or a burning smell, disconnect power when it is safe and seek immediate assistance. Do not repeatedly reset a breaker that continues to trip.
For normal troubleshooting, note what works on battery power, shore power and generator power before requesting service.
Common questions
RV electrical FAQ
Do you work on both AC and DC electrical problems?
Yes. RVs commonly use both 120-volt AC and 12-volt DC systems. The request form lets you describe when the failure occurs so the correct system can be evaluated.
Should I buy a new battery first?
Not necessarily. A battery may be discharged because of a charging, connection or parasitic-draw problem. Testing first can prevent unnecessary parts replacement.
