Current Output

  1. Disconnect "BAT" lead at alternator. Connect a 0-100 ampere scale DC ammeter in series between alternator "BAT" terminal and disconnected "BAT" lead wire. Connect positive lead of voltmeter to "BAT" terminal. Connect negative lead of voltmeter to ground. See Figure.
  2. Disconnect regulator harness connector. Connect a jumper lead from connector Green wire to ground. Connect a tachometer to engine and reconnect negative battery cable. Connect a variable carbon pile rheostat between battery terminals (open or off position). See Figure. Start engine.
  3. Adjust engine speed and variable carbon pile rheostat until a speed of 900 RPM (114-amp) or 1250 RPM (all others) and a voltmeter reading of 13 volts (114-amp) or 15 volts (all others) is obtained. DO NOT  allow voltage to exceed 16 volts. Observe ammeter. If current output is not within specification, remove alternator and proceed to BENCH TESTING.
