A towed agricultural machine includes a converter, configured to convert a first voltage potential generated by a generator to a second voltage potential. The second voltage potential powers a component of the towed agricultural machine. Further, the towed agricultural machine also includes a switch that senses the absence of the second voltage potential from the converter and switches to powering the subcomponent with a second voltage potential received from a source external to the towed agricultural machine. The second voltage potential output by the converter can also be combined, on a power bus, with the second voltage potential from the external source or another source.

An engine ignition shutdown module includes a voltage regulator circuit connected to a key switch, and a pair of isolated MOSFET driver circuits connected to the voltage regulator circuit. Each MOSFET driver circuit charges a capacitor while the key switch is in a run position and the interlock switches are closed, and each capacitor discharges through a resistor for a time delay period once the key switch is moved from the run position to an off position or at least one of the interlock switches are opened. A pair of high voltage output MOSFET transistors are switched on while the capacitors discharge and provide an output to a magneto ignition for the time delay period.
