Ignition Coil: Testing and Inspection
Ignition Coil and Ignitor Assembly
INSPECTION
Using an accurate tester, inspect the following items, and replace if defective.
1. Primary resistance
2. Secondary coil resistance
CAUTION: If the resistance is extremely low, this indicates the presence of a short-circuit.
Specified resistance:
[Primary side]
Between terminal No.1 and No.2 ..................................................................................................................................................... 0.73 Ohm ± 10%
Between terminal No.2 and No.4 ..................................................................................................................................................... 0.73 Ohm ± 10%
[Secondary side]
Between (A) and (B) ...................................................................................................................................................................... 12.8 kOhm ± 15%
Between (C) and (D) ...................................................................................................................................................................... 12.8 kOhm ± 15%
3. Insulation between primary terminal and case: 10 MOhm or more.
