M4027 Champion Aerospace HARNESS

IGNITION HARNESSES

The aircraft ignition harness carries an electrical current from the aircraft magneto to the spark plugs. An aircraft ignition harness is shielded to support and protect the wires from damage and to act as a conductor for stray magnetic fields. This in turn will minimize electrical interference with sensitive electrical equipment on the aircraft.

FAA-PMA approved Slick Harnesses by Champion are built to handle the maximum spark energy produced while delivering more energy than is required by the spark plugs - even during emergency full-power engine operation. Using anything less could result in more than a 50% reduction of radio sensitivity in commonly used communication frequencies, as tested by Champion. Features such as a heavy-gauge contact spring provide more contact area and force inside the spark plug, while the flexibility of the coiled center conductor reduces fatigue and breakage resulting from repeated temperature cycling and vibration.

Champion Ignition Leads have a polymer coating to resist heat and are engineered for high-temperature environments, which is common in reciprocating engines.
