Overcharge Condition

  1. If voltmeter indicates high voltage (more than 15.4 volts), turn ignition switch to ON position. Connect negative voltmeter lead to ground. Connect positive voltmeter lead to generator output connection at starter solenoid. Record voltage.
  2. Connect positive voltmeter lead to regulator "A" terminal screw on rear of generator. See Figure and Figure . If voltage difference between both locations exceeds 0.25 volt, repair high resistance condition in "A" circuit wiring.
  3. If excessive voltage still exists, check ground connections for both generator and regulator. Tighten regulator ground screws to 16-24 INCH lbs. (1.8-2.7 N.m.), and recheck output voltage.
  4. If excessive voltage still exists, connect voltmeter negative lead to ground. Connect positive voltmeter lead first to regulator "A" terminal screw, then to "F" terminal screw. Record readings. Different voltages at each screw head indicates a short in field circuit or a grounded rotor coil. To correct either condition, replace generator.
  5. If same voltage appears at both screw heads, no internal short to ground is indicated. Replace voltage regulator.
