TM 9--2350--292--20--10005 00--20THEORY OF OPERATION -- CONTINUED0005 00DEEP WATER FORDING KIT -- CONTINUEDSealingandMiscellaneousMaterials Non--hygroscopic tape is applied around the engine oil fill cap and oilgauge rod, transmission oil filler neck, electro magnetic clutch bayonet gauge and vent, main winch fill/tube/bayonetgauge and/or excessively large open areas if required.Fording sealer is used as a sealing compound around exterior stowage compartment doors, main winch cableopening, removable hull front cover and all mounting surfaces of the vehicle and deep water fording components.Electrical insulating and sealing compound is used to seal all exposed electrical connections.Wiping cloths are supplied to be used in cleaning and drying the vehicle preparatory to sealing.One spanner wrench is provided for installing bilge pump discharge hoses.ELECTRICAL SYSTEMBatteries Six 12--volt batteries are connected in a series--parallel circuit to give the vehicle a 300--ampere/hoursource of 24 V dc power. The batteries are located in the left side of the engine compartment.PositiveBus Distributes power from the batteries to the vehicle electrical systems.MasterSwitch Located on the Driver’s switch panel. When moved to ON, applies battery voltage to the electricalsystem. When engine is running, it supplies generator voltage to the electrical system.MasterRelay The master relay is located in the left rear of the engine compartment. It controls primary power toall electrical systems and components except personnel heater system, the MASTER switch and the NATO slavereceptacle.AuxiliaryPowerReceptacle(NATOSlave) Used to connect two vehicles together to charge batteries or jumpstart a vehicle.Starter The 24--volt, waterproof starter assembly is mounted on the lower left side of the engine towards the rear.It is a heavy--duty, solenoid--operated, enclosed shift--lever--type engine starter. The motor utilizes 12 brushes re-tained in six brush holders which are accessible through inspection plugs in the motor frame. The drive clutch is aheavy--duty over--running type with adjustable pinion clearance.LowVoltageProtectionModule Prevents starter operation below 12 volts.EngineGenerator Waterproof, oil--cooled 28 V dc, 650 ampere field regulated unit. Mounted on the right side ofengine (flywheel end) and is gear--driven by the engine. Engine oil is circulated through the generator for cooling.VoltageRegulator Maintains generator output voltage of the engine at a constant 28+0.7 V dc. Located left rearof engine compartment.AuxiliaryPowerUnit(APU) Power from the batteries powers the motor/generator to start the APU. Once started,the motor/generator generates 28 V dc to the APU voltage regulator.APUVoltageRegulator Receives 28 V dc from motor/generator and provides 28+0.7 V dc to charge the batteries.Located left rear of engine compartment.
