DRIVE BELT ADJUSTMENT (1)
Eclipse (2.0L Non-Turbo)
- Turn ignition switch off. Disconnect negative battery cable. Connect positive voltmeter lead to positive battery terminal. Connect negative voltmeter lead to ground.
- Disconnect generator output wire from terminal "B". Install a 100-amp ammeter in series with terminal "B" and disconnected output lead. (Схема №1) Connect positive lead of ammeter to terminal "B" of generator, and negative lead to disconnected output wire. Install a tachometer, and reconnect negative battery cable.
- Start engine. Ensure all lights and accessories are off. Operate engine at 2500 RPM and read voltmeter when generator output current drops to 10 amps or less. Voltage regulator is okay if voltage output is within specification. See «REGULATOR VOLTAGE SPECIFICATIONS»(ref-5346-S17477208962000081400000) table.
All Other Models
- Turn ignition switch off. Disconnect negative battery cable. On Galant, install Generator Harness Connector (MB991519) in-line with generator connector to facilitate connection of voltmeter. On all models, connect positive voltmeter lead to terminal "S" of generator. (Схема №1) Connect negative voltmeter lead to ground.
- Disconnect generator output wire from terminal "B". Install a 100-amp (130-amp on Diamante) ammeter in series with terminal "B" and disconnected output lead. Connect positive lead of ammeter to terminal "B" and negative lead to disconnected output wire. Install a tachometer, and reconnect negative battery cable.
- Turn ignition switch on and ensure voltmeter indicates battery voltage. If voltage is not present, check for open in wire between generator terminal "S" and positive battery terminal. Check for blown fusible link.
- Start engine. Ensure all lights and accessories are off. Operate engine at 2500 RPM and read voltmeter when generator output current drops to 10 amps or less. Voltage regulator is okay if voltage output is within specification. See «REGULATOR VOLTAGE SPECIFICATIONS»(ref-5346-S17477208962000081400000) table.
Note. If regulated output is 12.3 volts on 2.0L Turbo and 2.4L Eclipse models, check that terminal "G" of generator is not grounded.

REGULATOR VOLTAGE SPECIFICATIONS
Diamante
Remove generator relay. Relay is located in relay box, in engine compartment, near battery. Connect positive lead of ohmmeter to relay terminal No. 4. See WIRING DIAGRAMS . Connect negative lead of ohmmeter to relay terminal No. 2. Continuity should be present. Switch ohmmeter lead locations. Continuity should not be present. Replace generator relay if continuity is not as specified.
ROTOR
- Check continuity across rotor slip rings. Resistance should be 3-5 ohms (2-5 ohms on Galant and Montero Sport). Replace rotor if continuity is not present or resistance is not within specification.
- Check continuity between individual slip rings and rotor shaft. If continuity is present, rotor coil or slip ring is grounded. Replace rotor.
STATOR
Ensure continuity is not present between stator coil leads and stator core. Check continuity between leads of stator coil. If continuity is not present between coil leads, replace stator.
