Ignition Coil Resistance Test
- Turn ignition off. Remove wires from coil primary terminals to isolate it from the rest of the system. Set an ohmmeter to the low scale, and attach the leads to the coil positive and negative terminals. Check primary resistance reading.
- Set ohmmeter to x1000 scale. Attach leads to coil positive terminal and secondary tower. Check secondary resistance reading.
