RV Generator Troubleshooting Tips
GENERATOR TROUBLESHOOTING: Caution – Servicing a generator can create hazards – burns, cuts, fire and shock hazards. Exhaust fumes can be harmful.
Notes: Gasoline powered generators are fed from a midpoint on your main fuel tank. Most generator manufacturers recommend a minimum of one hour loaded run time per month to prevent carburetor gumming.
Generator will not crank: No 12 volt power or 12 volt fuse located on the control panel blown.The battery voltage should be above 9.5 VDC. Possible bad control board or poor wiring connections.
Generator will not start, but cranks: Poor 12 volt power from battery or convertor, bad cables or corroded battery posts, gasoline tank not full enough, carburetor clogged from disuse, spark plugs fouled, automatic choke linkage stuck, faulty oil pressure switch, dirty air filter, low oil level, damaged wiring, or corrosion on the control board.
Generator starts, then fails to run: Low oil level or low oil pressure, Low fuel supply, press the prime switch the recommend length of time, sticky choke linkage, or check the generator AC voltage output. Other voltage tests require an Operating Manual, Troubleshooting charts and learned personnel.
