3. Reconnect the spark plug load, with the spark plug removed from the turbine. Rest the body of
the spark plug against the turbine shell (or other grounded metal). Make sure the electrode end of
the spark plug is not grounded.
**WARNING**
Do not test ignitors in or near an area with an explosive
atmosphere.
Be careful of high voltage.
4. Energize the ignition circuit and check the spark of the spark plug for approximately two minutes.
If heating occurs along the length of the plug or the spark is weak or erratic, loosen the swagelock
fitting and slide out the spark plug and replace it. Do not compress the swagelock fitting at this
time.
