Current Output Test
- Turn ignition switch off. Disconnect battery ground cable. Disconnect "Bat" lead wire at alternator output terminal. See Figure .
Connect an ammeter (0-100 amp. minimum) in series with alternator "Bat" terminal and disconnected "Bat" lead wire. See Fig 1 .
- Connect positive lead of voltmeter (0-15 volt range) to "BAT" terminal of alternator. Connect negative lead to ground. Connect engine tachometer and reconnect battery ground cable.
- Connect a variable carbon pile rheostat between battery positive and negative terminals. Be sure carbon pile is in open or off position when connecting leads. Start engine and operate at idle speed.
- Adjust carbon pile and accelerate engine to specified speeds and measure current output. Do not permit voltage to exceed 16 volts. Compare ammeter readings with specifications.
