Engine Starter and Carburetor Choke Control
To get the engine starter to engage, the key switch is held in the start position which supplies
36 volts to the main machine controller on the violet wire with the green stripe to connector J7
pin 19. This is the start input request. The main machine controller receives a 12 V supply on
connector J3 pin 23 from the engine starter battery. It uses this voltage supply to send 12 volts out
of connector J3 pin 10 to the crank request relay coil. The other side of the relay coil is grounded
through the Woodward L-series actuator. With power and ground across the relay winding the
relay energizes and fused battery power from terminal 30 is sent to the starter solenoid. An
electrically operated solenoid pulls the carburetor choke closed when the starter is engaged.
