Fig. 4. Four-wire diagnostic cable.
The cable has the following marking:
"GC" (Yellow) is intended for connection to the alternator
voltage control terminal.
"FR" (Green) is intended for connection to the alternator
load control terminal.
"-" (Black) "B-" Battery negative pole (the alternator hou-
sing).
"+" (Red) "B+" Battery positive pole, the alternator output.
Used to power the device when testing the alternator on
the test bench or in the car; it is also used for "B+" voltage
indication.

4.1 Tester Menu

The main menu consists conditionally of three
sections (Fig. 6):
Fig. 6. Tester main menu.
1. Selection of the alternator type. The alternator type can
be selected by single-clicking on the corresponding icon.
The selected type is being highlighted.
2. Types of voltage regulator connectors are displayed as
26
reference information.
3. "HELP" and "TEST" buttons. Customer support contact
information is displayed when the "HELP" button is pres-
sed. Alternator testing mode is on when the "TEST" button
is pressed.

4.2 Alternator testing modes

The following information is displayed when the
testing mode for COM-type alternator is selected (Fig. 7):
Fig. 7. Diagnostic window of the "COM"-type alternator.
1. Type of the tested alternator;
2. "-V" and "+V" buttons are used to set the voltage on the
voltage regulator, which is displayed as "set + numerical
value". Each pressing of the button changes the value of
preset voltage by 0.2V. The measured is displayed in
green below the preset voltage.
3. "COM PR.": voltage regulator protocol type. The
following protocol titles appear in the display: LIN1.3
(displayed as LIN1), LIN2.0 (displayed as LIN2).
4. "ID": voltage regulator identification number. The manu-
facturer and the voltage regulator order number are enco-
ded in it. The ID number should correspond to the original
one, when mounting the voltage regulator on the car,
otherwise the car will reject such a voltage regulator and
the dashboard will display an error.
5. "COM SPEED": speed of data exchange between the
voltage regulator and vehicle ECU. The following speed
rates can be displayed int the "LIN" protocol:
• "L" - 2400 baud (low)
• "M" - 9600 baud (medium)
• "H" - 19200 baud (high)
6. "TYPE": voltage regulator connection type. The following
protocol types are displayed: "BSS" or one of the 12 types
of "LIN" protocol: A1, A2, A3, A4, B1, B2, B3, B4, C3, D1,
D2, E1.
