Question about 1994 Ford Mustang
Ignition Module is actually a class C amplifier. It amplify signal instead of music. Class C amplifier are very efficient type of ampifier. They are used to drive the flyback transformers in a television to create high voltage for the screen. In a car it drives the ignition coil to produce high voltage for the spark plug.
You can't test them unless you know electronics, but you can do an elimination process. Remove the ignition coil from the car, and bench test it. Note the postive and negative terminals. connect a spark plug to the output. and ground the spark plug at the negative side of the two terminals. Apply 12 volts to the terminal, then take off the positive side, as the voltage collapses a high voltage is induce firing the spark plug. The most likely item to go bad in an ignition system is the coil or the ignition module since they work the hardest. If the coil tested good you are almost sure it is the module.
