Basic Ignition System Checks: Dis: Spark

  1. If factory tachometer is connected to coil tachometer terminal, disconnect tachometer before performing tests. When removing spark plug wire from spark plug, twist and pull on boot. DO NOT pull on wire.
  2. Using Spark Tester (J-26792), check for spark at each spark plug wire. Leave other wires connected while checking for spark. Check spark plug wire resistance on suspect wires. Resistance should be about 30,000 ohms.
CAUTION: DO NOT insert DVOM leads into ignition coil connectors. Connector terminals may be damaged. When using DVOM, ensure lead only contacts front edge of terminals.
