Regulator/Rectifier Output Voltage Inspection
Remove the seat (see Frame chapter).
Check the battery condition (see Battery section).
Warm up the engine to obtain actual alternator operating
conditions.
Check that the ignition switch is turned off, and connect a
hand tester to the battery terminals.
Special Tool - Hand Tester: 57001-1394
Start t he engine and note the voltage readings at various
engine speeds with the headlight turned on and then off.
The readings should show nearly battery voltage when
the engine speed is low, and as the engine speed in-
creases, the readings should also increase.

Turn off the ignition switch, and disconnect the hand
tester.
If the regulator/rectifier output voltage is between the val-
ues given in the table, the charging system is working nor-
mally.
If the output voltage is m uch higher than the values spec-
ified in the table, the regulator/rectifier is defective or the
regulator/rectifier leads are loose or open.
If the battery voltage does not increase as the engine
speed increases, then the regulator/rectifier is defective
or the alternator output is insufficient for the loads. Check
the alternator and regulator/rectifier to determine which
part is defective.
