TM 1-1500-204-23-4(1)Compass compensation. Remoteindicating compass compensation procedures are thesame as the magnetic compass, except that whencompensating, the power supply to the compass mustbe turned on.(2)Testing and replacement criteria. Do notreplace components of remote indicating compasswithout first testing wiring for proper continuity (seefigure 4-24), and the indicator for correct operation.Test indicator by using the following procedures:(a)Using P-1, ANASM61, orANASM339V1 tester, test indicator and transmitter forproper operation. Refer to applicable tester technicalmanual for operation and connection of tester, andapplicable wiring diagram for location of transmitter.(b)When the remote magneticcompass does not read within specified tolerances,check applied voltage. If power supply is functioningproperly, troubleshoot system in accordance withapplicable TM 11 series maintenance manual.(c)Replace either indicator ortransmitter when faulty.q.Electrical Liquid Indicating Systems andIndicators. Electrical liquid indicating systems are usedfor fuel quantity and anti-icing fluid quantity. Atransmitter in the liquid tanks transmits an electricalsignal to position the pointer of a gauge in the cockpit.Refer to applicable aircraft maintenance manual fortesting and troubleshooting procedures.r.PositionIndicatingSystemsandIndicators.Position indicating systems are used to indicate positionof landing gear and flaps. A cockpit indicator showsrelative position of landing gear and flaps. Refer toapplicable aircraft maintenance manual for testing andtroubleshooting procedures.s.RepairandReplacements. The followingparagraphs describe repair and replacement ofinstruments and instrument system components that canbe accomplished on the flight line.(1)Repair. Line repair is limited primarily tothe following:·Resoldering broken leads·Replacing tubing, hose, andfittings·Removing obstructions fromrigid or flexible tubing·Recompensating compasssystems·Removal and replacement ofcomponentsFigure 4-24.
