  1. Remove distributor cap and pull out coil high tension lead. With breaker point closed, turn ignition on. Place coil high tension lead about 3/16" (4 mm) away from a known good ground.
  2. Open and close points using a wooden (insulated) stick. A spark should occur at end of coil high tension lead. If not, check for voltage at igniter terminal No. 1 and check that terminal No. 3 is grounded.
  3. If voltage/ground circuit at terminals is okay, turn ignition off. Disconnect terminal No. 1 and 4 from igniter. Install a 0.22 microfarad condenser on coil negative terminal.
  4. Disconnect ignition coil negative lead. With ignition on, manually ground and open coil negative terminal. If no secondary voltage is produced, ignition coil is defective. If secondary voltage is produced, igniter or breaker points are defective.
