Hello,
Working on a legacy herc with a digital fuel qty system installed. We keep getting error code E7 displayed on the L/h aux indicator. Only, the fault is intermittent. E7 is apparently a compensator fault. So far we have changed the compensator, wiring from the L/h Fwd wing pressure break to the boundary connector, and calibrated the indicator. Also, reterminations of all the connectors completed to ensure no corrosion, bad wiring.Any thoughts?
