Question about Onan Generator
Something I have never understood about generators (I have an Onan 6.5 Emerald III.) A 12-volt DC battery is used to start the generator, which then produces 120V AC. The battery supplies the energy ...

the Emerald III had a small (1 amp) charging system, using a stator winding labeled the "B" winding. this winding operated the electric choke heater on older models, and provided enough 12v, using a resistor and diode on control board for fuel pump and ignition system, and controls. Newer (last 20 years or so) generators relied on RV converter to keep batteries from discharging. Commercial versions all have 12v charging systems. BTW...NEVER a good idea to disconnect battery from generator when running. Like a car alternator, you risk shocking and damaging control board components.
