SECTION 4.2
OPERATIONAL ANALYSIS
DC CONTROL
PART 4
The battery charge relay (BCR) connected to Wire
14 will be de-energized. This will cause transformer
(TX) voltage to power the battery charger again.
Circuit board action will connect the engine's
ignition shutdown module (ISM) to ground, via Wire
18, circuit board Pin 13, and Wire 0. Ignition will be
terminated.
Without fuel flow and without ignition, the engine
will shut down.
