With Internal IC Unit

Fig. 12 Exploded view of IC type distributor with internal IC unit (typical):





The internal IC unit includes the IC circuitry and pick-up coil windings in a single assembly, Fig. 12.

If voltages and external components check within specifications, but a no spark condition exists, replace IC assembly.
