Figure 6-15 HEI Ignition System (4-Terminal)
As the timer core turns inside the magnetic pick-up, its
triangular points pass very close to the magnet's
points. When this happens, a small volt-age is
generated and sent to the HEI module (figure 6-15).
The voltage signal coming from the pickup coil is
alternating current. The microprocessor, however, will
not work with alternating current. Hence, the module
contains a converter that changes the volt-age to
direct current and a square wave.
HEI eliminates the point set to keep better pace with
engine speed. HEI will not wear or change timing, and
it provides more voltage to the spark plugs.
