Secondary Resistance

Be sure ignition is still "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 first). Ohmmeter reading should be 7, 700-9, 300 ohms with coil temperature at 77° F. With coil temperature at 200° F or above, a maximum reading of 12, 000 ohms is acceptable.
