Ignition Coil: Testing and Inspection
Measurement of Input Voltage1. Ignition switch is in "ON" position.
2. Measure the voltage between (+) terminal of coil and ground. The approximate value should be 12 volts.
Ignition coil resistance measurement
Check Ignition coil with ohmmeter for opens and grounds.
1. Use high scale
Standard: Infinite Ohms
If not as specified, replace the ignition coil.
2. Use low scale
Standard: Very low or zero Ohms
If not as specified, replace the ignition coil.
3. Use high scale
Standard: Infinite Ohms
If not as specified, replace the ignition coil.
