Power Transistor: Description and Operation
Ignition Module
PURPOSE
To amplify the ignition signal from the Engine Control Module (ECM).
OPERATION
The ignition signal from the ECM is amplified by the power transistor, which turns the ignition coil primary circuit on and off, inducing the proper
high voltage in the secondary circuit.
