This was posted by rickdb1boat on another thread, but I thought it would be easier to find if it had it's own dedicated thread. It applies to two cylinder engines but the cheklist concept would be roughly the same for all engines...

Johnson/Evinrude Troubleshooting
Alternator Driven CD Ignitions
1978-2002
Two Stroke/Except Ficht
Two Cylinder Engines
No Fire at All:
  1. Disconnect the black/yellow kill wire and retest. If the engine's ignition has fire, the kill circuit has a fault-check
    the key switch, harness and shift switch.
  2. Check the stator resistance. You should read approximately 500 ohms from the brown wire to engine ground.
    (See DVA Charts).
  3. Check the DVA output from the stator. You should have a reading of at least 150V or more from the brown wire to brown/yellow (while connected to the pack).
  4. Check the timer base’s resistance from the black/white wire to the white/black wire. Reading should be 10-20 ohms or 38-42 ohms.
  5. Check the DVA output from the timer base. A reading of at least 0.5V or more from the black/white wire to the white/black (while connected to the pack) is needed to fire the pack.
  6. Check the cranking RPM. A cranking speed of less than 250-RPM will not allow the system to fire properly.
  7. Check the DVA output on the orange wires from the power pack while connected to the ignition coils. You should have a reading of at least 150V or more. If the readings are low, disconnect the orange wires from the ignition coils and reconnect them to load resistors. Retest. If the reading is now good, the ignition coil is likely bad. A continued low reading indicates a bad power pack.
