RV electrical problems often stem from faulty transfer switches, loose connections, or blown breakers in the main panel. Most 120V shore power issues can be diagnosed by checking the transfer switch operation, main breaker panel, and power distribution connections systematically.
The RC7-GS inverter charger can properly charge 105Ah AGM batteries using the 125Ah setting, as AGM charging is voltage-based, not capacity-dependent. Generator start issues typically stem from wiring problems or incorrect DIP switch configurations.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Fix your RV refrigerator with this guide covering Dometic, Norcold, and residential fridge issues.
External generators need signal wire to trigger ATS, which is only connected to onboard genset. Solutions include manual bypass switch, simulating the run signal, or universal voltage-sensing ATS.
When your RV has no power despite being plugged into a working campground pedestal, the issue is typically a bad shore power cord, faulty transfer switch, or tripped main breaker inside the RV's electrical panel.
Your generator likely uses the chassis battery and may have a weak connection or failing starting battery. The main engine alternator charges the chassis battery when running, explaining why the generator starts after running the engine.
Ekko with 640Ah lithium and 450W solar can boondock 3-5 days easily, indefinitely in good sun. Monitor usage, charge devices during peak solar hours, and use propane for cooking.
Honda 2200 easily powers RV converter for charging 330Ah battery bank. Generator supplies 1800W continuous; converter typically draws 800W or less. Full charge from 50% takes 4-6 hours depending on converter amp rating and battery chemistry.
The Onan 5500 can be tuned up with quality aftermarket parts when OEM parts are unavailable. Use NGK 3432 spark plugs, Wix 57358 oil filter (not 57398), and zinc-containing oils like Rotella T6 for optimal performance.
Yes, many 2021+ Ford F53 chassis owners report needing spark plug, coil, and wire replacement well before 20,000 miles due to known quality control issues. Early replacement with quality aftermarket parts often resolves misfires and improves performance significantly.
Your Onan 7000 generator fuel pump is receiving only 9V instead of the required 12V, causing starting issues. This voltage drop is typically caused by corroded connections, faulty control board, or wiring problems in the fuel pump circuit.
Sudden power drop on QG5500 likely means lost phase, failed capacitor, or thermal protection activation. Check voltage on both legs and inspect for overheating. Test capacitors if voltage is low.
Generator shutdown causes voltage drop that trips inverter into fault. Common with AGS systems. Solutions include adjusting transfer switch timing, inverter sensitivity settings, or generator governor. May need to reset inverter after each AGS cycle.
RV dual indicators typically show paired readings like fresh vs gray water levels, house vs chassis battery, or current vs set temperature. Check your RV manual or panel manufacturer for specific meanings.
