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.

the location of the firmware file "MS013COM.dfu".
7. Press the button "Upgrade". The following notification will appear on finishing the firmware
process:
8. Disconnect USB cable from the device. The firmware has been updated and the device is ready
for further use.
6. STEP-BY-STEP INSTRUCTION
Adapter MS013 tests the alternator assembly (the alternator assembled with the voltage regulator)
directly in the car or separately the voltage regulator only. Both variants are considered further.
6.1. T
Testing in the car is carried out with the help of four-wire cable (Fig. 2). The adapter is connected
to the car electrical system according to the color marking described in the point 3.2. For accurate
voltage measuring, the adapter’s negative wire should be connected to the corresponding battery
terminal. The testing is conducted in the following sequence:
• Connect the adapter to the car electrical system.
• Start the car engine and wait until it operates steady at idle.
• Check the voltage value on the display. If the value is lower than the nominal one, check the
alternator belt tension.
• Change the alternator voltage value (if the alternator model implies changing the value). The
voltage on the adapter should coincide with the set one. Otherwise, the voltage regulator
should be tested separately from the alternator.
User Manual - Adapter MSG MS013 COM
17
• Check the alternator operation under average rotation frequency of the crankshaft when battery
charge is full. Increase load on the alternator by turning on the headlights and other lighting
devices. FR value should change as well. If voltage is within the norm, the voltage regulator is
faultless. If voltage is above or below the norm, check the voltage regulator and replace it if
necessary. If voltage is out of the norm, the alternator should be dismounted from the car for
repair.
• Connect the control terminal of the alternator back to the car.
• Check the adapter’s indication. If the alternator output voltage value exceeds the norm, check
the signal in data transmission line ("LIN", "CAN", "K-LINE") in the mode of oscillograph.
• Stop the engine.
• Disconnect the adapter terminals from the car.
WARNING!Testing must be carried out in the premises with combined extract and input
ventilation or fume offtake system. Otherwise, testing must be conducted outdoors.
6.2 T
Testing of the voltage regulator separately from the alternator is conducted with the help of
nine-wire cable (Fig. 3). The device is connected to the voltage regulator according to the color
marking described in the point 3.2 and Appendix 2. The testing is conducted in the following
sequence:
• Connect the adapter to power supply through USB connector.
• Select the needed option in the menu with the buttons "⇧", "⇩".
• Connect all the needed voltage regulator outputs. Tips with the most common types of
connectors will appear on the screen.
• Enter the testing mode with the button "⏎".
• Follow the display indication and adjust voltage with the buttons "⇧", "⇩". If the voltage regulator
is faultless, the measured voltage should change for "B+" when changing the set voltage; and
there should be no errors in COM voltage regulators.
• Exit the testing mode with the button "⏎".

lightened by another color. Set the needed duty cycle value with the buttons "⇧", "⇩".
• To change the frequency, press the frequency set area on the display. The numbers will be
lightened by another color. Set the needed frequency value with the buttons "⇧", "⇩".
• Exit the testing mode with the button "⏎". Disconnect the wires.
6.4 "O"
In this mode connection to the source of analized signal is carried out with the help of the four-core
cable using the wires with black (negative) and yellow (GC) color marking.
• Select the option in the adapter's menu with the buttons "⇧", "⇩".
• Enter the testing mode with the button "⏎".
• Connect the wires "GC" and "-" from the adapter’s output to the signal source.
• The results will be oscillographically displayed on the display of the adapter.
7. SAFETY MEASURES WHEN WORKING WITH MS013 COM
In order to avoid possible electric shock or injury as well as damage of the adapter or a tested
equipment, the following instructions should be strictly observed:
• Make sure that the measuring clamp does not have insulation damage or bare metal spots.
Make sure that the clamp is not damaged. In case of obvious damage, change it for a new one
before using the adapter.
• In order to avoid possible electric shock or injury as well as damage of the adapter, do not apply
voltage exceeding 20V to the adapter outputs or between the earth and any of the outputs.
