Maintenance of Parallel Cable Assemblies. These procedures apply for both the reactive load and governor
(1) Inspect. See Figure 3-9. Perform visual inspection on parallel cable assemblies as follows:
(a) Inspect plug connectors on both ends of the parallel cables. Check for cracks, deformities, and other
damage. Check that the conductor terminals Inside each connector are free from dirt, other obstructions,
and damage. Check mounting hardware on cable connectors for possible cross-threading.
(b) Lay out the parallel cable assemblies. Inspect cable bushings and cable insulation sleeves for cracks,
cuts, ruptures, and other damage. Check that the cable clamps are securely mounted.
(c) Check that the cable marker bands are clearly legible and securely attached to the corresponding cable.
(2) Replace. Replace defective reactive current parallel cable assembly or governor parallel cable assembly.
Refer to the next higher level of maintenance for repair.
Maintenance of 120 V AC Receptacles, Lights, and Switches.
(1) Inspect. See Figure 3-10.
(a) Visually Inspect all light fixtures. Check for broken light bulbs and loose mountings.
(b) Open all junction boxes Check that all electrical connections inside boxes are secure. Check for shorted,
frayed, or broken wires, and for signs of overheating. Replace covers on boxes after inspection.
(c) Check receptacles, lights, and switches for loose mountings, damage, and signs of overheating. Check
that receptacle boxes and covers are undamaged.
(2) Test. Turn on 120 V ac auxiliary power Turn switches ON to verify light bulb operation. With voltmeter,
check for presence of 120 V ac line In receptacles.
(3) Repair See Figure 3-11
(a) Replace light bulbs that do not function.
(b) Refer any obvious deficiency (e g loose connections, shorted wires, loose hardware) uncovered during
visual inspection to the next higher level of maintenance.
Inspect Magnetic Pickup PU1. The magnetic pickup PU1 (Figure 3-3) is located on the left side of the engine
flywheel housing. Inspect the magnetic pickup for broken or damaged wires and ensure that it is mounted
securely to the flywheel housing. If any damage is noted as described above, refer the magnetic pickup PU1 to
the next higher level of maintenance.
MAINTENANCE OF FUEL SYSTEM.
Inspect Fuel Transfer Pump. See Figure 1-3 and Figure 3-12 If the fuel transfer pump falls any of the following
inspections, refer to the next higher level of maintenance.
(1). Lines and Fittings. Check the hoses from the fuel transfer pump (1, Figure 3-12) to the fuel strainer (2) and
the hoses from the duplex filters (3) to the fuel transfer pump (1) for leaks and secure mounting.
(2). Fuel Transfer Pump. Check the fuel transfer pump (1) for excessive noise or sluggish operation. Check for
(3). Overall Appearance. Visually Inspect overall appearance to ensure that pump Is free of dirt, sand, and other
(4). Motor. Check for overheating and broken or frayed wires (10).
