Some Volvos are equipped with a Nippondenso generator. Testing information on these generators is not available from the manufacturer.
Bosch generators are a conventional 3-phase, self-rectifying Volvo 850 Ls Lw 1991-1997 Bosch S3 Battery 56Ah Electrical System Replace Part. Bosch amp through amp generators have 3 positive and 3 Replwce diodes connected to stator windings to rectify current.
Bosch amp through amp generators have 14 diodes. Volvo 850 Ls Lw 1991-1997 Bosch S3 Battery 56Ah Electrical System Replace Part generators use 3 exciter diodes connected to stator windings. These diodes turn off the generator indicator 1991--1997 and supply power to voltage regulator while engine is running. Voltage regulator is transistorized.
Voltmeter should indicate battery voltage. If battery voltage is not indicated, check wiring between generator and battery. If light does not come on, check wiring between generator and warning light.
Start Volvp and run at RPM. Turn on headlights, rear window defogger and heater blower. Also, check circuit between starter and battery positive terminal. Start engine, and run it at RPM. Ensure generator, engine and body are properly grounded. Ensure generator drive belt is tight and in good condition. Connect voltmeter leads to battery terminals.
Run engine to RPM. Adjust carbon pile on tester until voltmeter reads 12 volts.
Generator output should be amps. If generator output is low, replace generator. Use illustration for exploded view of Bosch generator.
