Primary Coil Testing

7.

Using an ohmmeter, measure resistance between ignition coil (+) and (-) terminals.

Primary Resistance (Cold):

1.2 - 1.5 ohms

Secondary Coil Testing

8.

Using an ohmmeter, measure resistance between ignition coil (+) and the secondary terminals.

Secondary Resistance (Cold):

7.7k - 10.4k ohms

9.

Check ignition coil for signs of carbon tracking, burned or discolored plastic, external leakage, or cracks in the housing.

10.

If ignition coil resistance is not within specifications or physical damage is apparent, replace ignition coil.

Pickup Coil Testing

11.

Disconnect primary wire connector at distributor.

12.

Using an ohmmeter, measure resistance between terminals the pick-up coil terminals.

Pickup Coil Resistance:

130 - 210 ohms

13.

If resistance was not within specifications, replace pick-up coil assembly. If no faults were found, proceed with this test.
