    Going over the engines I found a loose/broken wire in the engine junction control box. I have the schematic, but can anybody explain the operation? Specifically the inlet air heaters?

    Are they temperature or time controlled?

    Is there a test proceedure for the heaters themselves? I think there are 3 connections, and either 2 or 3 wires as I recall.
