Ignition Coil: Testing and Inspection
INSPECTIONUsing 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.
