Charging System Chrysler Crossfire I final

The charging system consists of

1. Generator
2. Electronic Voltage Regulator
3. Ignition Switch
4. Battery
5. Generator Lamp
6. Check Gauges Lamp
7. Wiring harness and connections

The charging system is turned on and off with the ignition switch. The system is on when the engine is running. The Check Gauges Lamp monitors: charging system voltage, engine coolant temperature and engine oil pressure. If an extreme condition is indicated, the lamp will be illuminated. This is done as reminder to check the three gauges. The lamp is located on the instrument panel. Refer to DESCRIPTION .

The following procedures may be used to diagnose the charging system if

1. the check gauges lamp is illuminated with the engine running.
2. an undercharged or overcharged battery condition occurs.

Remember that an undercharged battery is often caused by

1. accessories being left on with the engine not running.
2. a faulty or improperly adjusted switch that allows a lamp to stay on.

INSPECTION

The Powertrain Control Module (PCM) monitors critical input and output circuits of the charging system, making sure they are operational. A Diagnostic Trouble Code (DTC) is assigned to each input and output circuit monitored by the On-Board Diagnostic (OBD) system. Some charging system circuits are checked continuously, and some are checked only under certain conditions.

To perform a complete test of the charging system, perform the following inspections.

1. Inspect the battery condition.
2. Inspect condition of battery cable terminals, battery posts, connections at engine block, and starter solenoid. They should be clean and tight. Repair as required.
3. Inspect all fuses in the Underhood Accessory Fuse Block for tightness in receptacles. They should be properly installed and tight. Repair or replace as required.
4. Inspect generator mounting bolts for tightness. Replace or tighten bolts if required.
5. Inspect accessory drive belt condition and tension. Tighten or replace belt as required.
6. Inspect the automatic belt tensioner.
7. Inspect generator electrical connections at generator field, battery output, and ground terminal. Also check generator ground wire connection at engine. They should all be clean and tight. Repair as required or replace generator if necessary.

Scheme 2

The generator (1) is belt-driven by the engine using a serpentine type accessory drive belt (2). It is serviced only as a complete assembly. If the generator fails for any reason, the entire assembly must be replaced. The only component that is replaceable is the voltage regulator.

OPERATION - GENERATOR

As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a current into the windings of the stator coil. Once the generator begins producing sufficient current, it also provides the current needed to energize the rotor.

The Y type stator winding connections deliver the induced AC current to 3 positive and 3 negative diodes for rectification. From the diodes, rectified DC current is delivered to the vehicle electrical system through the generator battery terminal.

Noise emitting from the generator may be caused by: worn, loose or defective bearings; a loose or defective drive pulley; incorrect, worn, damaged or misadjusted drive belt; loose mounting bolts; a misaligned drive pulley or a defective stator or diode.

Scheme 3

1. Disconnect the negative battery cable.
2. Remove the right side air inlet tube. CAUTION: The accessory drive belt tensioner pulley is spring loaded and can cause damage to hands and fingers if allowed to spring back.
3. Remove the accessory drive belt from the generator pulley. Refer to «REMOVAL»(/chrysler/crossfire/i-final-2008-2008/remont/accessory-drive-belts/#engine-cooling-system-automatic-transmission-cooling-system) . Pull the tensioning pulley in a counter clockwise direction. Lock the tensioning pulley with a pin or slowly release the pulley after the belt is free from the area.
4. Remove the upper generator bolt (2).
5. Remove the lower generator bolt (3) and reposition the generator to access the generator harness connectors.
6. Remove the protective plastic cap from the generator B+ cable retaining nut (5).
7. Disconnect the generator B+ cable and the generator harness connectors (4) from the rear of the generator.
8. Remove the generator (1).

INSTALLATION - GENERATOR

1. Connect the generator B+ cable with the retaining nut and connect the generator harness connector (4). Tighten the generator B+ cable retaining nut to 15 N.m (11 ft. lbs.).
2. Install the protective plastic cap on the generator B+ cable nut (5).
3. Install the generator (1) into the mounting bracket.
4. Install the upper and lower generator mounting bolts. Tighten the generator mounting bolts to 42 N.m (31 ft. lbs.). CAUTION: Be sure to check proper installation on all pulleys.
5. Install the accessory drive belt. Refer to «INSTALLATION»(/chrysler/crossfire/i-final-2008-2008/remont/accessory-drive-belts/#engine-cooling-system-automatic-transmission-cooling-system) .
6. Install the right side air inlet tube.
7. Connect the negative battery cable.

Scheme 4

The voltage regulator (2) is a separate component attached to the rear of the generator assembly (1). If replacement is necessary, the voltage regulator can be replaced separately from the generator.

Scheme 5

1. Remove the generator (1). See «REMOVAL»(/chrysler/crossfire/i-final-2008-2008/remont/charging-system/#charging-system) .
2. Unclip the plastic voltage regulator cover (4) and remove.
3. Remove the screws (3) attaching the voltage regulator to the generator.
4. Remove the voltage regulator (2).

OPERATION - VOLTAGE REGULATOR

The amount of DC current produced by the generator is controlled by the voltage regulator circuitry. This circuitry is connected in series with the generators second rotor field terminal and its ground.

INSTALLATION - VOLTAGE REGULATOR

1. Insert the voltage regulator (2), ensure that the ground lug is making contact to the voltage regulator.
2. Install the screws (3) attaching the voltage regulator to the generator.
3. Install the plastic voltage regulator cover (4) with the clips.
4. Install the generator (1). See «INSTALLATION»(/chrysler/crossfire/i-final-2008-2008/remont/charging-system/#charging-system) .
