Ignition Coil Primary Resistance

Disconnect ignition coil 3-pin connector. Refer to the ELECTRICAL COMPONENT LOCATIONS table at beginning of article. Disconnect power output stage 3-pin connector. Measure resistance between matching terminals of each connector (terminals No. 1 and 1, 2 and 2, and 3 and 3). See Fig 1 . If resistance is not 0.5-1.0 ohm, replace appropriate coil.
