Ignition Coil

To check primary resistance, remove wires from positive and negative primary terminals. Set an ohmmeter in the x1 scale. Connect ohmmeter leads to positive and negative terminals. Reading should be 0.63 - 77 ohms. If not, replace ignition coil.
To check secondary resistance, remove coil wire from coil tower. Set ohmmeter for x1000 scale. Attach ohmmeter leads to negative terminal and coil tower. Reading should be 7, 000-8, 600 ohms. If not, replace ignition coil.
