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 No.1 and No.2
0.69 Ohm - 10 %
Between No.2 and No.3
0.69 Ohm - 10%
[Secondary side]
Between terminal (A) and (B)
21.0 kOhm - 15 %
Between terminal (C) and (D)
21.0 kOhm - 15 %
[Insulation]
Between primary terminal and case 10 MOhm or more
