Current Transformer
See Figure 2-25. The current transformer (CT1) monitors
load voltage. Load fluctuations are instantaneously
signaled to the ECM to maintain optimal fuel delivery
during load transitions.

Engine Charging Components
Engine Stator
See Figure 2-26. The engine stator works in conjunction
with the engine mounted Voltage Regulator to generate
charging voltage for the 12 VDC battery during operation.
