GENERAL
Repair of harnesses and power pack wiring is limited to replacement of faulty connectors and
receptacles and to the substitution of a jumper wire for a defective harness wire.
When repair
is necessary, free the lead, harness or cable only insofar as necessary to effect the repair.
This
consists of disconnecting the connectors or receptacles at each end, and loosening or removing
cable clamps or removing tie wraps as required.
Removal of the complete harness, especially
in case of the longer and more complex harnesses, should be avoided.
The electrical system wiring harness assembly for engine Models 2CA and 2DA is made up of
two major circuits, the engine circuit and transmission circuit. The engine circuit includes
leads for the starter, starter low voltage protection module, generator, generator blower motor
(Model 2DA only), manifold heater system, engine oil pressure and oil temperature
transmitters, fuel solenoids, fuel/water separator automatic drain module, and hour meter.
The
transmission circuit includes leads for the neutral safety switch, oil pressure and oil
temperature transmitters, and manifold heater solenoid.
The electrical system wiring harness assembly for engine Model 2DR is made up of one major
circuit.
The engine circuit includes leads for starter solenoid wiring harness, generator,
generator blower motor, manifold heater system, oil pressure and oil temperature transmitters,
fuel solenoids, fuel shutoff, governor solenoid, auxiliary generator oil pressure switch,
fuel/water separator automatic drain module, hour meter, and transmission oil pressure and
temperature transmitters.
