Current Output Test
- Connect an ammeter in series between positive battery terminal and alternator battery "+" terminal. Connect carbon pile rheostat to battery, ensuring carbon pile rheostat is in the OFF position before connecting to battery. Start engine and allow it to idle. See Fig 1.WARNING: Ensure carbon pile rheostat is OFF before connecting to battery.
- Turn on all accessories. Load battery with carbon pile rheostat to obtain maximum amp output. Maintain voltage at 13 volts or more. If ammeter reads less than 60 amps, replace alternator. See the ALTERNATOR SPECIFICATIONS .
