What happens when you start a generator in an RV?

This is what normally happens when you start your genset. Pressing and holding the start switch causes the control board to send 12 volts to the ignition, fuel pump, choke heater, start solenoid and field flash circuits. The engine then cranks and starts. Oil pressure and generator voltage build up within 1-2 seconds.

What happens when you turn off the genset?

This is what happens when you stop your genset. Pressing and holding the stop switch for a few seconds causes the control board to cut off the 12 volts to the ignition and fuel pump (and/or fuel solenoid valve) causing the engine to stop. On models equipped with magneto ignition, the control board grounds the magneto kill circuit.

What causes a generator to shut down at low oil level?

This can be caused by low fuel level (not getting gas), vapor lock (too hot, gas is boiling), fuel contamination (water or dirt in fuel and/or filter) or a faulty fuel pump (insufficient fuel pressure). Models equipped with low oil level (LOL) switches will shut down the engine on low oil level.
