1. A gas turbine engine comprising:
a high pressure spool and a low pressure spool, the low pressure spool including a low pressure shaft operably connected to a fan, the high pressure spool including a high pressure shaft operably connected to a high pressure turbine, the low pressure shaft and the high pressure shaft being co-axial with one another;
a rotor of an electric starter generator coupled to the high pressure shaft;
a stator disposed radially outward of the rotor;
a high pressure shaft bearing;
a forward strut supporting the high pressure shaft bearing;
a first plurality of conductors electrically coupled to the stator and extending radially through the forward strut to an outer casing of the gas turbine engine; and
a second plurality of conductors electrically coupled between the stator and the first plurality of conductors, wherein the second plurality of conductors extend substantially axially,
wherein radially inward ends of the second plurality of conductors are staggered in a radial direction.
