Regulator/Rectifier Output Voltage Inspection - Dinli DL-801 Service Manual

Regulator / Rectifier Output Voltage Inspection
● 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
the hand tester to the battery terminal.
● Start the engine, and note the voltage readings at various
engines speeds with the headlight turned on and then
turned off. The readings should show nearly battery
voltage when the engine speed is low, and as the engine
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
disconnect the hand tester.
If the regulator/rectifier output voltage is kept between the
★
values given in the table, the charging system is
considered to be working normally.
If the output voltage
★
specified in the table, the regulator/rectifier is defective or
the regulator/rectifier leads are loose or open.
If the battery voltage does not rise as the engine speed
★
increases, then the regulator/rectified is defective or the
alternator output is insufficient for the loads, check the
alternator and regulator/rectifier to determine which part is
defective.
