ABSTRACT:
A simple continuity circuit is provided interconnecting the connector bodies of a wiring harness which directs the signal from the computer control of a gas turbine engine to the fuel metering unit of said engine. The continuity circuit forms part of the ignition exciter circuit and acts to de-energize the exciter when the wiring harness is not in place. This prevents ignition when the failure mode of the fuel metering unit is directing a fuel flow to the combustor which is excessive for safe start-up.
