Secondary Winding Resistance Test
- Remove high voltage ignition wire from high voltage terminal of ignition coil. Ensure ignition is off. Set ohmmeter for x1000 scale and zero pointer.
- Contact ohmmeter to brass contact in high voltage terminal and to either primary winding terminal. The resistance should be 7700-9300 ohms at 75°F (24°C). A maximum of 112,000 ohms is acceptable if coil temperature is 200°F (93°C) or more.
