Basic Ignition System Checks: Distributor: Spark
Crank engine, checking for spark at coil wire and each spark plug wire using Spark Tester (J-26792). If spark exists at some spark plug wires, check for defective distributor cap and/or defective rotor. Check spark plug high tension wire resistance. Spark plug high tension wires resistance should be 3000-6700 ohms per foot. Replace spark plug high tension wires if resistance exceeds specification.
