3.2. Using the alternator drive control buttons (see item 1 in Figure 26), set the speed of the
alternator pulley rotation within the range of 100 to 150 rpm.
WARNING! If the alternator pulley has a freewheel clutch, carefully select the direction of
rotation.
3.3. Visually assess whether the alternator rotates normally. If there are noises or vibrations
from the alternator indicating mechanical malfunction or incorrect alternator installation, stop
the diagnostics by pressing the "Cancel" button.
3.4. To continue the diagnostics, press the "Ok" button.
4. Evaluate the operation of the voltage regulator according to the following criteria:
4.1. If the diagnosed alternator is of the COM or IStars 12V type, the bench should identify the
alternator's ID, COM speed, and TYPE, and the Errors indicator should display a message about
mechanical malfunction "MEC".
4.2. If the alternator has a control lamp, the indicator of the control lamp should light up
(see item 1 in Figure 23).
5. Conduct a check to determine at what RPM the alternator starts generating, for this:
WARNING! For alternators with a voltage regulator terminal labeled "A" or "IG" or "15",
activate the "K15" button.
5.1. Gradually increase the speed using the alternator drive control buttons until the output 5.1
For alternators that have a control lamp indicator, it goes out at the moment of generation start.
5.2 For alternators without control lamp indicator, the moment of generation start is determined
at the moment of establishment of operating voltage from 13.9 to 14.8 V for 12V alternators, and
from 28 to 29.8 V for 24V alternators.
5.3 For alternators of COM or IStars 12V type, the mechanical error disappears at the moment of
generation start.
6. Evaluate the operation of the voltage regulator by:
6.1. Setting the drive speed within 1500-2000 rpm.
