Common Signs You Need Electrical & Battery Systems
If any of these sound familiar, give us a call — we can usually tell you over the phone how serious it is.
- Half your outlets are dead even though you're plugged into shore power
- Lights flicker or dim when you turn on the microwave or AC
- House batteries won't hold a charge overnight
- You hear a buzzing or popping noise from the power panel
- There's a faint burning or plastic smell near the converter or panel
- The generator starts but shuts off after a few minutes
- Breakers trip the moment you turn on a specific appliance
Common Problems We Fix
Real failure modes we see on Orange County RVs — and how we repair each one.
Failed converter / charger
Old WFCO and Magnetek converters either stop charging the batteries or overcharge and cook them. We replace with multi-stage chargers sized to your battery bank.
Bad shore power cord, plug, or pedestal connection
Burned plug blades, melted housings, and bad transfer switches all cause partial power inside. We test and replace the failed segment.
Dead or sulfated house batteries
Lead-acid batteries left undercharged sulfate and won't hold capacity. We test under load and recommend replacement or a lithium upgrade.
Inverter failures and undersized installs
Pure sine inverters die or get overloaded by a microwave or AC. We diagnose, replace, and properly size for the loads you run.
Wiring shorts and chafed harnesses
Vibration causes wires to chafe through insulation, especially near slides and the front cap. We locate shorts with the right tools instead of pulling everything apart.
Transfer switch and 50A/30A surge issues
Failed transfer switches cause partial outages when switching from shore to generator. We test and replace as needed.
What Happens If You Ignore It
Small RV problems compound fast. Here's what we see when these issues get put off too long.
- A failing converter can overcharge and destroy a $1,000+ battery bank in a matter of weeks.
- Burned or arcing shore power plugs are a fire risk — we've seen plenty of melted pedestals and cord ends.
- A chafed 12V wire shorting to the frame can start a fire faster than you can react.
- Running a generator that shuts off repeatedly will eventually damage the AC compressor and electronics from voltage sags.
What's Included
- 12V & 120V troubleshooting
- Converter & inverter replacement
- Shore power & transfer switch repair
- Battery & lithium upgrades
- Solar system service
- Outlet & circuit repair
How We Fix It
- 1Meter-based diagnosis
We measure voltage at the converter, batteries, shore inlet, transfer switch, and breakers — and trace from there.
- 2Repair or upgrade
Converters, inverters, transfer switches, batteries, and most wiring repairs are same-visit fixes.
- 3Battery and lithium installs
Lithium conversions include sizing the charger, inverter, DC-DC charger, and any wiring upgrades. Most installs in 4–6 hours.
- 4Load test
We test under realistic load (AC, microwave, fridge, lights) before we sign off.
How Much Does Electrical & Battery Systems Cost?
Outlet, breaker, and small wiring repairs are the most affordable; converter, transfer switch, and inverter replacements are mid-range; full lithium battery system conversions are the highest tier and vary widely by bank size.
Lithium upgrades especially benefit from a written quote — we walk you through every component before ordering.
What affects the price
- Battery chemistry (AGM vs lithium) and bank size
- Inverter size and whether new wiring is needed
- Whether shore power components need replacement
- Solar array size for solar installs
