A start circuit controlled by an electronic control unit for providing power from one or both of a battery and TRU in parallel to a starter motor coupled to a gas turbine engine. The circuit includes contactors between the TRU and battery and a junction where the current from the TRU and battery combine. The circuit further includes two additional contactors in series between the junction and the starter motor. Voltage sensors and contactor position sensors are employed for diagnostics. A novel method of starting the engine using the start circuit contem...
[ What is claimed is:] [1.]1. A start circuit controlled by an electronic control box for providing power from one or both of a battery and TRU in parallel to a starter motor, said circuit comprising:a first contactor in parallel with a second contactor, said first and second contactors being controlled by said electronic control box;a junction for summing the current through said first contactor and said second contactor;a third and fourth contactor in series and disposed between said junction and said starter motor, said third and fourth contactors bei...
