Power Transistor: Description and Operation

 Power Transistor

The power transistor, located on the inner side of the strut tower, 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.
