Current Output

  1. Connect an ammeter in series with positive battery cable. Connect positive voltmeter lead to positive battery post and negative lead to negative battery post.
    CAUTION: Carbon pile testing is part of this procedure. To avoid explosion, turn carbon pile OFF before connecting it to or disconnecting it from vehicle battery.
  2. Connect carbon pile rheostat to battery, ensuring carbon pile rheostat is in the OFF position before connecting to battery.
  3. Start engine and reduce speed to idle. Turn on all accessories. Load battery with carbon pile rheostat to obtain maximum amperage. Maintain voltage at 13 volts or more.
  4. If ammeter reads within 15 amps of rated output, alternator is okay. If ammeter does not read within 15 amps of rated output, replace alternator. See ALTERNATOR SPECIFICATIONS  at the end of this article.
