1 h a s s i s l e c t r i c a l harging System The charging system provides electrical current for the lights, radio, heater blower and the engine s electrical systems. It also maintains the batteries in a charged state, recharging them as necessary to provide cranking power. The charging system has three main components, or component areas: the alternator, the voltage regulator, and the battery. The alternator is driven by a belt from the engine crankshaft and produces the electrical power to operate the systems on the bus. It also recharges the battery. The voltage regulator acts as a control valve for the alternator output. It senses the current load and maintains a constant voltage in the charging system, independent of the current load, up to its rated output. The alternator on the lue ird ll merican has a built in voltage regulator. It is excited (started) by the ignition system. The battery is the reservoir of chemical electrical power. Its primary purpose is to crank the engine. It also supplies power to the accessories for a short time when the demand is too high for the alternator alone (i.e., while the bus is at idle). nother key role of the battery is to act as a filter for the charging system by providing clean electronic power for the electronic control systems; U, M, TM, and gauges. Maintenance lean the alternator and all connection points. irt buildup restricting air flow through to the alternator will cause excessive heat and premature failure. orrosion at any connecting point will produce resistance to current flow, heat and diminished power for the accessories. nsure that all the components in the charging system are mounted securely. heck the torque at all mounting bolts both the bolts that hold the alternator in the mounting bracket and the bolts that secure the mounting brackets to the engine. The torque value for mounting bolts at the engine and at the alternator should be 60 0 ft lb. lue ird ll merican buses are equipped with an automatic belt tensioner. nsure that all the grooves fit properly into the pulleys in the correct path. The drive belt should be inspected every,000 miles (,00 km), 0 hours of service life, or every months; whichever occurs first. 89 lso check: attery voltage lternator output Starter current draw

2 s e r v i c e m a n u a l Troubleshooting Timely preventive maintenance of the charging system should keep it running smoothly. owever, when a problem occurs, effective troubleshooting procedures will help locate and correct the problem quickly and economically.

8 s e r v i c e m a n u a l Starter There are main components or component areas in the starting system: the ignition switch, a neutral safety switch, the starter solenoid, the starter motor and the batteries. When the key is turned to the start position, electrical current flows to the starter solenoid from the batteries. The flow is interrupted if the transmission shift lever is not in the neutral position or if the neutral sensor switch is defective. The starter solenoid is an electromagnetic switch mounted on the starter motor. When electric current energizes coils inside the solenoid, a magnetic field is induced which pulls a plunger. t one end of this plunger is a lever. The lever is connected to the starter drive pinion of the starter motor. The plunger also connects the electrical power from the batteries to the starter motor as the drive pinion engages the flywheel ring gear. The starter motor is a relatively small electric motor, but it can deliver large amounts of torque for a short time. When the operator releases the ignition switch it returns to the run position. The solenoid is disconnected from the batteries and the magnetic field collapses. This allows the spring in the solenoid to move the plunger in the opposite direction, disengaging the drive pinion from the flywheel and removing electrical current from the starter motor. The lue ird ll merican has a -volt electrical system. 86 Preventative Maintenance There are two preventative maintenance procedures that can greatly enhance the efficiency of the starting system. These two steps are also the first two steps taken when troubleshooting a malfunctioning starting system. n engine that needs a tune up will be difficult to crank; over cranking will lead to starter motor failure. Poor connections due to road dirt, grease, corrosion, loose connectors, or broken insulation at any connecting point rob the starting system of electrical power and cause it to over-crank. Troubleshooting efore beginning to troubleshoot the starting system, ensure the batteries are properly maintained and charged to at least % of their rated capacity. drained battery will cause any further diagnostic tests to be inaccurate. ommon causes of starting system malfunction include:. battery that is low, poorly charged, or defective places high demands on the starting system; voltage at the battery should be. volts or greater to crank the engine. If the batteries aren t adequately charging, a problem in the charging system. Refer to the lternator section of this Service Manual for information on the charging system.

9 c h a s s i s e l e c t r i c a l. starter motor can be damaged by heat that is generated by excessive cranking. The starter should never be engaged for more than 0 seconds. It must rest (cool off) a minimum of minutes between starting attempts.. oose, dirty, or corroded connections in the starting system rob the system of the power needed to turn the engine. The case of the starter motor is the ground or return connection for the starter motor and solenoid.. loose starter motor will allow vibration that can damage the motor. In addition, the ring gear could be damaged.. Improper or excessive use of starting fluid will cause extra stress on the starting system. 6. defective solenoid will fail to engage the starter drive pinion of the starter motor. failed pull-in coil will cause the plunger to fail to pull in. failed hold-in coil may cause the starter to fail to stay engaged, or may fail to switch the starter motor on. If the solinoid is suspect, test the wiring of the solenoid circuit before replacing the solenoid. 8

10 s e r v i c e m a n u a l Ignition/Run Test egin by determining whether the problem is with the ignition switch or the pilot relay, and their associated wiring; or if it is in the solenoid and/or starting motor. To begin with the ignition switch: Volt/Ohm Meter. onnect the positive lead of a VOM to the ignition switch terminal on the solenoid.. onnect the negative lead of the VOM to the chassis ground. Solenoid lternator. While attempting to crank the engine, record the voltage displayed on the VOM. Observe the following: Starter No voltage ow voltage Normal voltage with slow cranking Normal voltage with no cranking at all.. onnect a remote start switch to the positive battery post.. onnect the other end of the remote start switch to the ignition post of the solenoid ttempt to crank the engine with the remote switch. Record the voltage displayed on the VOM. If there is less than volt difference from the previous reading, the ignition switch is okay. If there is more than volt difference, the switch is defective.. With the VOM negative lead connected to the chassis ground, move through the switch system one connection at a time. If your first voltage test has revealed low voltage, the starter motor may be shorted. 8. If the first voltage test indicated normal voltage, but there is slow cranking or no cranking at all, a problem with the batteries, battery cables, or a damaged starter motor is indicated.

11 c h a s s i s e l e c t r i c a l ow Voltage Test There are various reasons for low voltage but the troubleshooting methods are the same. If the solenoid clicks, it means that either current is flowing through the solenoid contacts but not through the main contacts; or that the current through the main contacts is insufficient due to low batteries. Solenoid Volt/Ohm Meter. onnect the positive lead of the VOM to the starter motor terminal of the solenoid. lternator. onnect the negative lead of the VOM to the chassis ground. Starter. While attempting to crank the engine, if there is no voltage displayed on the VOM, the main contacts are not functioning properly.. If there is voltage present at the solenoid terminal during Step, the problem is in the starter motor or its cabling.. If the first voltage check in Step under Ignition/Run Test indicated normal voltage but slow or no cranking, the next step is to check the starter motor and its connections. 6. If the drive pinion jumps out of mesh with the flywheel ring gear, check for a broken or loose ground wire at the solenoid.. While attempting to crank the engine, place an ammeter on the positive battery cable. If the power drain is higher than the OM specifications, the starter motor is defective. n exception would be if the engine was not properly tuned or is difficult to turn over; in which case, a new starter motor would be a temporary fix.
