Ignition Coil and Ignitor Assembly: Inspection

Using the accurate tester, inspect the following items, and replace if defective.

• Secondary coil resistance
  CAUTION:

  • If the resistance is extremely low, this indicates the presence of a short-circuit. 
  • Ignitor is integrated in coil. Therefore, primary coil resistance can not be measured. 

  Specified resistance: 

  [Secondary side] Between (A) and (B) 

  12.8 kΩ+/-15% 

  Between (C) and (D) 

  12.8 kΩ+/-15%
