Mercury Cougar Ignition Control Module

The Ignition Control Module in the Mercury Cougar regulates coil firing to deliver a strong, well-timed spark to the engine. After key turning and relay closing, it gets battery power and then opens and closes the coil primary rapidly to produce high voltage which leaps the plug gap. The early Mercury Cougar vehicles were equipped with a distributor-based Ignition Control Module which utilized a magnetic pickup or hall switch, and timed advance was done with centrifugal and vacuum hardware. Over time, models changed to use distributorless designs where an Ignition Control Module receives signals from crank and sometimes cam sensors so the computer can command all timing. Though both types use the same trigger in principle, one style is triggered by the distributor and the other by the crank sensor. Both, however, cut coil current far quicker than breaker points for hotter sparks. The Ignition Control Module likewise protects Mercury wiring from heavy current, preserving Cougar electronics in both systems. If the Ignition Control Module fails, the starter still turns but your Mercury Cougar cranks without spark, and simple voltage checks or flicker checks confirm a failure occurs.
