COIL TEST
Turn ignition off. Disconnect ignition coil electrical connections. Using a DVOM, measure resistance of primary and secondary coil circuits. Measure primary circuit resistance between battery terminal and terminal for cylinders being checked. Resistance should be between .51-.61 (ohms @ 70-80 degrees F) See Fig. 10 .
Measure secondary circuit resistance across coil towers. See Fig. 11 . Resistance should be 11,500-13,500. If resistance is within specification, ignition coil is okay. If resistance is not within specification, replace ignition coil.
