Power Transistor: Description and Operation

 Power Transistor

The power transistor, located on the R.H. side of the intake plenum, is a low current switch. It allows the signal sent from the ECU (very low
current) to activate the primary circuit in the ignition coil (much higher current). This induces high voltage in the secondary windings of the
ignition coil, providing spark to the distributor cap and plugs.
