Secondary Checks

  1. Disconnect high voltage wire from one spark plug and using insulated pliers, hold wire 1/2" from engine. Crank engine and check for spark. If spark occurs, ignition system is OK.
  2. If no spark occurs, disconnect high voltage coil wire from distributor. Using insulated pliers, hold it 1/2" from engine. Crank engine and check for spark. If spark occurs now, problem is with distributor cap, rotor or spark plug wires. If no spark occurs, proceed with following tests until problem is corrected.
