Ignition Coil: Testing and Inspection
InspectionUsing accurate tester, inspect the following items, and replace if defective.
CAUTION: If the resistance is extremely low, this indicates the presence of a short-circuit.
1. Primary resistance
Between No. 1 and No. 2 0.73 Ohms ±10%
Between No. 2 and No. 3 0.73 Ohms ±10%
2. Secondary coil resistance
Between (1) and (2) 12.5 K.Ohms ±15%
Between (3) and (4) 12.5 K.Ohms ±15%
3. Insulation between primary terminal and case 10 K Ohms +
