1. DESCRIPTION
The Adapter MS013 COM is used for diagnostics of alternator voltage regulators. The device gives an
opportunity to test voltage regulators both separately from the alternator and in assembly with the
alternator with the test bench for diagnostics of alternators, or directly in the car. Contemporary
voltage regulators (alternators) with COM (LIN/BSS) terminal cannot be properly tested without
such diagnostic adapter. The diagram below provided by the company Bosh illustrates that these
types of voltage regulators oust the others and can be mounted in low-cost cars by now:
The Adapter MS013 COM simulates control signals for the tested voltage regulator. It contains
integrated physical interfaces and program protocols of all actually existing voltage regulators. The
device’s control is easy and user-friendly, the indication is very convenient due to the color 4.3” TFT
display.
The main feature of this device is an opportunity to update software through USB port if new
protocols appear.
The adapter has additional functions: a PWM generator and an oscillograph. They can be useful
when repairing both the alternator and the whole car.

3. CONTROL UNITS
"UP" button is used to select the needed option in the menu. In the РР testing mode
increases the value of the needed electric pressure (except "L/D+" mode).
"Down" button is used to select the needed option in the menu. In the РР testing
mode decreases the value of the needed electric pressure (except "L/D+" mode).
"Enter" button is used to enter/exit the testing mode.

The device has D-SUB 9 pin connector to connect diagnostic cable (CAB) and USB connector to
connect diagnostic cable for supply and software update.
Two diagnostic cables are also included in the equipment set:
Fig. 2 – Four-wire cable for testing the voltage regulator in the car
The cable has the following marking:
• GC (yellow) is used for connection to the alternator voltage control terminal (COM, SIG, RLO, C,
D, RVC, etc.).
• FR (white) is used for connection to the alternator load control terminal (for P/D alternator – to
P terminal for displaying alternator rotation speed).
• "-" (black) – "B-". Battery negative pole (the alternator housing).
• "+" (red) – "B+". Battery positive pole, the alternator output. It is used for power supply of the
device when testing the alternator on the test bench or in the car; it is also used for "B+" voltage
indication.

Fig. 3 – Nine-wire cable for testing the voltage regulator apart from the alternator
The cable has the following marking:
• "FLD" (green) is used for connection the voltage regulator brushes and for field winding
simulation. Polarity is not important while connection.
• "ST"(blue) is used for connection to the voltage regulator stator winding leads. Polarity is not
important while connection.
• "B-" (black, the bigger) is negative pole of the battery (the alternator housing).
• "L" (black, the smaller) is used for connection to the voltage regulator "Lamp" lead.
• "+" (red, the bigger, the smaller) is used for connection to the voltage regulator "B+" lead.
• GC (yellow) is used for connection to the alternator voltage control terminal ("COM", "SIG", "RLO",
"C", "D", "RVC" etc.).
• "FR" (white) is used for connection to the alternator load control terminal (for "P/D" alternator – to
"P" terminal for displaying alternator rotation speed).
The adapter is also equipped with USB cable for software update and connection to power supply.
WARNING!Do not use USB ports of a laptop or a computer as supply source as far as
consumed current (up to 1-1,5А when testing some types of voltage regulators) may exceed the
one the PC port can provide.
