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.
