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.
Your Generac 7.5kW diesel generator likely has a damaged starter solenoid or starter motor from extended cranking with a weak battery. Check connections, test the solenoid, and inspect the starter before seeking professional repair.
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.
Guide to safely updating RV infotainment and navigation systems. Covers finding valid updates, preparation steps, and troubleshooting common issues.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
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.
Onan code 36 indicates a low fuel pressure issue in LP generators. This typically means a problem with the LP regulator, fuel solenoid, or gas line obstruction preventing proper fuel flow to the generator.
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.
Onan fault codes display via LED blinks or digital display. Common codes include 12-overspeed, 13-low oil, 14-high temp. Consult model-specific service manual for complete code list. Persistent codes may require professional diagnosis.
Shutting down under load after rebuild suggests carburetor still not delivering enough fuel or governor sticking. Watch governor arm movement during load test. Try gradual load increase to find threshold. Check fuel pump output if equipped.
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.
Your RV ATS isn't transferring shore power to your AC system due to likely faulty internal contactors or control board issues. This typically requires professional repair as ATS units contain high-voltage components and complex switching mechanisms.
Consistent 2-minute shutdown under load indicates fuel delivery cannot keep up with demand. Check fuel pump, bleed system, verify no restrictions. Also check if generator is undersized for AC load - may need soft start on AC unit.
