medium severity
Test the 12V (battery/converter) and 120V (shore power) systems separately: check that the converter charges, outlets and the inverter work, and the breaker panel is clean. Common issues are failing converters, corroded connections, and bad batteries, most are fixable but should lower your offer.
What it means
RVs run dual electrical systems, 12V DC from the battery for lights/pumps and 120V AC from shore power or generator for outlets and AC. Faults can be nuisance-level or fire risks.
Symptoms & signs to look for
- Lights dim or flicker on battery
- Outlets dead on shore power
- Converter not charging the battery
- Burnt smell or scorched outlets (serious)
What to inspect
- Plug into shore power and test every outlet
- Confirm the converter charges the battery
- Test the inverter, if equipped
- Inspect the breaker/fuse panel for corrosion or scorching
