Spark (RX7)

  1. Crank engine. Using a spark tester (or by holding wire 5/16" from ground), check for a strong Blue spark at coil wire and at each spark plug wire. Check spark plug wire resistance on suspect wires.
  2. Using ohmmeter, check resistance of high tension leads. Resistance should be 4878 ohms per foot. Disconnect and inspect all related ignition system connectors and harnesses. Clean or repair as necessary and recheck spark. If connectors and harnesses are okay, go to LEADING SIDE IGNITOR (RX7).
CAUTION: During testing procedure, ensure high tension leads remain connected to coil. Disconnecting of high tension leads may cause high voltage sparks. Ensure battery is fully charged.
