CHECKING THE IGNITION COILS
The following procedure applies to all of the ignition
coils.
1. Check:
    • Primary coil resistance

      If out of specification -> Replace.
Primary coil resistance
     2.16 - 2.64 ohms
      a. Disconnect the ignition coil connectors from the ignition coil terminals.

      b. Connect the pocket tester (ohms x 1) to the ignition coil as shown.

     90890-03112

Analog pocket tester
     YU-03112-C
    • Positive tester probe -> black/red "1"
    • Negative tester probe ->orange or gray/red "2"
      c. Measure the primary coil resistance.

2. Check:
    • Secondary coil resistance

      If out of specification -> Replace.

Secondary coil resistance
     8.64-12.96 Kohms
      a. Disconnect the spark plug cap from the ignition coil.

      b. Connect the pocket tester (ohms x 1 k) to the ignition coil as shown.
