^ Disconnect the wire(s) from the ignition coil.
Coil Resistance Test:
^ Measure ignition coil resistance:
Primary: Positive to Negative 0.8-1.6 Ohms
Secondary: Positive to High Voltage 6k-30k Ohms
NOTE: Refer to image for Ohmmeter hookups.
^ Are the resistance readings within specifications?
YES -- Go to Computers and Control Systems / System Diagnosis / Diagnostic Charts (Pinpoint Tests) / IDM - Ignition Diagnostic Monitor.
