2. Component Description
A. Ignition Cable
(1) The ignition cables are used to transmit 5 kilovolts from the exciters to the igniter.
(2) The cables are connected at one end to the ignition exciter and at the other end to the igniter.
(3) The ignition cables are flexible braided steel conduits with ceramic insulated terminals at the plug end and are interchangeable.
B. Igniter
(1) The igniter use the 5 kilovolts from the ignition exciters to make an electrical spark across the plug gap.
(2) The electrical spark ignites the fuel/air mixture in the combustor.
(3) The igniter are attached to the diffuser case at the 3 o'clock position. Each igniter goes through a hole in the diffuser case and into the combustion chamber.
(4) The igniter have shielded center electrodes.
(5) Classified spacers are installed under a mounting boss and are used to control the immersion depth of the igniter.
