Ignition Coil Power Source
- Disconnect ignition coil 2-pin harness connector. Turn ignition on. Check for voltage at appropriate wire at ignition coil harness connector. See IGNITION COIL POWER SOURCE TERMINAL IDENTIFICATION table.
- If voltage is present, check ignition coil resistance. See appropriate IGNITION COIL RESISTANCE table. If voltage is not present, check continuity of entire circuit between battery and ignition coil, including fusible link and ignition switch. See POWER DISTRIBUTION section in SYSTEM WIRING DIAGRAMS article.
