14-30 ELECTRICAL SYSTEM
Charging Voltage (regulatorlrectifier's output voltage)
• Inspect the charging condition of the battery (see Battery
• Warm up the engine to obtain actual alternator operating
• Turn the ignition switch OFF.
• Connect the hand tester in accordance with the following
Charging Voltage (regulator/rectifier's output voltage)
Battery Position (+)
Battery negative (-)
14 - 15 V
• Start the engine, and note the voltage readings at vari-
ous engine speeds with the headlight turned on and then
turned off. (To tum off the headlight of US, Australia and
Canada models, disconnect the headlight connector in
the upper fairing.) The readings should show nearly bat-
tery voltage when the engine speed is low, and as the en-
gine speed rises, the readings should also rise. But they
must be kept under the specified voltage .
• Turn off the ignition switch to stop the engine, and discon-
nect the hand tester.
If the regulator/rectifier output voltage is kept between the
values given in the table, the charging system is consid-
ered to be working normally.
If the output voltage is much higher than the values spec-
ified in the table, the regulator/rectifier is defective or the
regulator/rectifier lead are loose or open.
*If the battery voltage does not rise 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
