Ignition Coil Resistance Test
- Turn ignition switch "OFF". Set an ohmmeter in the low scale and attach its leads to the coil positive and negative terminals. Coil should be isolated from rest of system. Check primary resistance reading. Replace coil if not to specifications.
- Set ohmmeter in x1000 scale and attach leads to positive primary terminal and secondary tower. Check secondary resistance reading. Replace coil if not to specifications.Ignition Coil Resistance Specifications (Ohms)
