⁽¹⁾	Information is not available from manufacturer.

⁽²⁾	Use DVOM to measure resistance between terminals No. 1-2, 1-3 and 2-3. See Fig 1 . If resistance reading between any two terminals is 0 ohms (shorted) or infinity (open), replace ignition coil assembly.

⁽³⁾	Use DVOM to measure resistance between terminals: No. 1-2 should read 11,000-12,000 ohms, No. 1-3 should read 2,000-3,000 ohms and 2-3 should read 13,000-14,000 ohms. If the ignition coil assembly values exceed the limit replace assembly.
