Generator Output
NOTE:
On Protege, generator output is controlled by PCM. If a generator no charge or overcharge condition exists, check PCM DTCs. See appropriate G - TESTS W/CODE article in ENGINE PERFORMANCE section.
- Except Protege
Connect an ammeter (100-amp minimum) in-line between generator terminal "B" connector and terminal "B" of wiring harness connector. See Fig 1, Fig 2, Fig 3 or Fig 4 . Turn headlights and all accessories on. Depress brake pedal. Operate engine at 2500-3000 RPM. - Measure and record generator output. See GENERATOR MAXIMUM RATED OUTPUT table. If amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator.
- Turn off headlights and all accessories. Release brake pedal. Operate engine at 2500-3000 RPM and measure amperage under no-load condition. No-load amperage should be 5 amps or greater. If amperage is as specified, go to next step. If amperage is not as specified, repair or replace generator.
- Operate engine at 2500-3000 RPM. Measure voltage between ground and terminals "S" and "L". If 14.1-14.7 volts does not exist, repair or replace generator. If 14.1-14.7 volts exists, generator output is okay.
