Ignition Coil Primary Resistance
- With ignition switch in "OFF" position, disconnect ignition coil connector. Inspect connector for dirt, corrosion or damage. Measure resistance across ignition coil positive and negative terminals. See Figure.
- Resistance should measure .3-1.0 ohm. If so, ignition coil primary circuit is okay. Proceed to IGNITION COIL SECONDARY RESISTANCE test. If resistance is less than .3 ohm or greater than one ohm, replace ignition coil.
