Ignition Coil Resistance Test
- Turn ignition switch "OFF". Remove wires from coil primary terminals to isolate it from the rest of the system. Set an ohmmeter in the low scale, and attach the leads to the coil positive and negative terminals. Check primary resistance reading. Replace coil if not to specifications.
- Set ohmmeter in x1000 scale, and attach leads to the coil positive terminal and secondary tower. Check secondary resistance reading. Replace coil if not to specifications.
