The time between these events is the dwell period or coil saturation time, determined by the Engine Control Module (ECM) or ignition amplifier. The feedback signal tells the ECM that ignition has occurred. Measure the resistance of the ignition coils. Coil – with internal resistance. The first step in checking to see if the ignition coil has fried, is to test for spark directly on the ignition coil tower. My confusion with it is the Manual says in Step 1: "Disconnect all ignition coil wires (including the spark plug leads) before testing." To test the secondary windings in the coil, put one lead from the ohm-meter to each end of the spark plug wire connections. If your coil's actual resistance levels fall outside of these specifications, you'll know that your coil is damaged. Your coil should have a reading of between 6,000 and 15,000 ohms for your Ford.

"Ignition coil primary resistance = 0.5 to 0.9 Ohms Ignition coil secondary resistance = 5K to 10K Ohms" Today, I measured the secondary of one of my coils (did not remove the coil from the engine) and I measured 6.24K Ohms from tower to tower. In fact, using a non-resistor plug or low resistance spiral wound spark plug wire in most applications may actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels, abnormal combustion and probable damage to the ignition and/or ignition coil. This can be checked using a voltmeter (to measure resistance) but it is required to remove the wire connection between the coil and the points.
