Secondary Resistance

Turn ignition switch "OFF". Set ohmmeter to high scale (x 1000 scale) and connect one lead to coil negative terminal and other lead to coil tower (remove coil secondary wire). Ohmmeter reading should be 7, 700-9, 300 ohms with coil temperature at 75° F. With coil temperature at 200° F or above, a maximum reading of 12, 000 ohms is acceptable.
