TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 CHAPTER 10 MAINTENANCE OF INTERCONNECTING ELECTRICAL HARNESSES AND PARALLEL CABLE ASSEMBLIES Section I. MAINTENANCE OF INTERCONNECTING ELECTRICAL HARNESSES 10-1. GENERAL. Electrical interconnection of control devices and indicators is accomplished through wiring harnesses. Wires in the harnesses are bundled and secured to prevent unnecessary movement and chafing, and to conserve space. 10-2. REPLACEMENT. Replace the interconnecting, external power box, AC-DC control box or control cubicle harness if 30 percent of the wires in the assembly are defective. Refer to FO 10-1 through 10-21. WARNING SET MAINTENANCE LOCKOUT SWITCH TO LOCKOUT. DISCONNECT NEGATIVE CABLE FROM BATTERIES. REMOVE EXTERNAL POWER BY OPENING CB101 (120V RECEPTACLE BREAKER). a. Removal. Remove harness assembly as follows: (1) Tag all wires, connectors, and terminal boards. (2) Disconnect harness connectors from receptacles by unscrewing connectors in counterclockwise direction. (3) Remove all clamps that secure the harness. b. Repair. Refer to Operator/Crew Organizational Maintenance manual for repair procedures. c. Replacement. Replace harness as follows: (1) Secure harness with clamps. (2) Make necessary connections. (3) Remove wire tags. Section II. MAINTENANCE OF PARALLEL CABLE ASSEMBLIES 10-3. GENERAL. There are two parallel cable assemblies, a reactive load compensation cable and a governor circuit cable, used to interconnect sets for parallel operation. 10-4. INSPECTION. a. Inspect connectors for damaged threads and bent, loose, or missing pins. Inspect wiring for defective insulation. b. Perform continuity check, using ohmmeter between connecting points in the cable. Use wiring data in figure 10-1. Check for short circuits between connector pins of the same receptacle. 10-5. REPAIR. If a wire is broken from a connector, resolder and reassemble. 10-6. REPLACEMENT. To remove parallel cables, unscrew connectors from receptacles on generator set AC- DC control panel to replace parallel cables, unscrew dust caps on AC-DC control panel receptacles, labeled GOVERNOR PARALLELING CIRCUIT and REACTIVE LOAD COMPENSATION. Attach parallel cables to these receptacles at both generator set AC-DC control panels. 10-1
