Ignition Coil and Ignitor Assembly

Testing

Primary Side Test

1. Using a Digital Multi-meter, inspect the resistance of the primary ignition coil and replace if out of spec.

2. Disconnect the ignition coil electrical connector

3. Install a DMM set to read Ohms between terminals 1 and 2
   •  Resistance specification: 0.73 Ohm ±10%
4. Install a DMM set to read Ohms between terminals 2 and 4
   • Resistance specification: 0.73 Ohm ±10%

CAUTION
If resistance is extremely low, this indicates a short-circuit.

Secondary Side Test

1. Using a Digital Multi-meter, inspect the resistance of the secondary ignition coil and replace if out of spec.

2. Disconnect the spark plug wires from the ignition coil

3. Install a DMM set to read Ohms between (A) and (B)
   • Resistance specification: 12.8 kOhm ±15%
4. Install a DMM set to read Ohms between (C) and (D)
   • Resistance specification: 12.8 kOhm ±15%
5. Insulation between primary terminal and case: 10 MOhm or more
