Abstract
Some embodiments relate to an engine driven generator that includes a first electrical fan and a second electrical fan. The engine driven generator further includes a power source and a circuit connecting the power source to the first electrical fan and the second electrical fan. The circuit is configured to selectively connect the first electrical fan and the second electrical fan in series or in parallel. The circuit may operate the first electrical fan and the second electrical fan at full speed when the first electrical fan and the second electrical fan are electrically connected in parallel. The circuit may operate the first electrical fan and the second electrical fan at less than full speed when the first electrical fan and the second electrical fan are electrically connected in series.
