Power Transistor: Description and Operation

Fig. 34 Power Transistor and Ignition Coil

The power transistor, located on the coil bracket on the left frame rail below the air intake tube, 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.
