Ignition Coil Power Source

WARNING: This page is about a different car, the 1989 Honda Accord. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect ignition coil primary leads. See Figure . Turn ignition on. Using voltmeter, check voltage between ground and Black/Yellow wire terminal of ignition coil harness.
  2. Battery voltage should exist. If not, check for open in Black/Yellow wire between coil and ignition switch. On some models, an in-line radio noise condenser (mounted on distributor or near coil) is utilized. If condenser shorts out, power supply will be interrupted and vehicle will not start.
