• When using an arc welder, always disconnect the ground lead from the lift truck battery to prevent alternator or battery damage. Attach the welding ground clamp as close to the weld area as possible to prevent welding current from damaging the bearings. The diodes and resistors in the electrical system can be damaged if the following cautions are not followed: • Do not disconnect the battery when the engine is running. The voltage surge can damage the diodes and resistors in the electrical system.
• • Do not disconnect an electric wire before the engine is stopped and the switches are OFF. • Donotcauseashort circuit by connecting the electric wires to the wrong terminals. Make sure a correct identification is made of the wire before it is connected. • Makesureabattery is the correct voltage and polarity before it is connected. • Do not check for current flow by making a spark because the electronic components can be damaged. NOTE: Information on alternators manufactured outside the United States is in the SRM (Service Repair Manual) sections for lift trucks that use those alternators. This section has a description and the repair procedures for the alternator with a voltage regulator as part of the alternator.
• Description NOTE: For this SRM section, the alternators are in two groups: Type A and Type B. The two types are very similar, but the Type A alternators have a set of three diodes (diode set) as well as the diode bridge. The Type B alternator has zener diodes as part of the diodes in the diode bridge. This alternator does not have a diode set, but does have an additional fan inside the rear housing. The basic operation of both types is very similar. The alternator generates an alternating current when the engine is running
• . The alternator is either ON or OFF. The alternator generates maximum current when it is ON and no current when it is OFF. The regulator switches the alternator between ON and OFF to get the average current needed to charge the battery. Alternator output is directly changed by engine speed and rotor field current. The alternating current is changed to a direct current by the diode bridge inside the alternator.
