Alternator Output Test
- With engine off, disconnect White wire from alternator battery terminal. See Fig 1. Connect ammeter positive lead to alternator battery terminal, and negative lead to wire just removed. Connect voltmeter to battery.
- Start engine. Turn on high beam headlights, rear window defroster, and turn heater fan switch to highest setting. Run engine at 3000 RPM. Ammeter should show about 60 amps for Accord and Prelude, 50 amps on Civic. Check alternator if not to specification.
