INTRODUCTION
The actual Operation Manual contains the description of a diagnostic process. The purpose is to
assess the technical condition of alternators and voltage regulators (separately from
alternators), and to read data transmitted via a LIN bus.
WARNING! The actual instruction does not provide a description of all the diagnostic aspects.
If you lack knowledge or experience, we recommend you to take training at the equipment
manufacturing facility.
The tester purpose is as follows:
1. Assessing performance of automotive alternators with a nominal voltage of 12/24V and
stop-start alternators with a nominal voltage of 12/24V (VALEO I-StARS). The diagnosis is carried
out either on a car or on the test bench that provides its drive and a load on the alternator.
2. Assessing performance of voltage regulators separately from alternators.
3. Reading and saving data transmitted via the LIN bus of a vehicle («LIN analyzer» function).
4. Diagnosing starters directly on cars without their removal or on the test bench that provides
proper unit fixation and power supply using cable MS-33503.
WARNING! Cable MS-33503 is not included in the equipment set and can be purchased
separately.
Below are the criteria for alternator and voltage regulator performance assessment:
- stabilizing voltage;
- control lamp operation;
- FR (displayed FR signal frequency and waveform, voltage regulator feedback).
For COM voltage regulators:
- ID;
- Protocol type;
- Data exchange rate;
- LIN protocol type;
- Voltage regulator self diagnosis faults.

1. TESTER DESCRIPTION
The tester is a portable device, its functions controlled via the touch-screen (Fig.1).
Figure 1 - General view of the tester
In the upper part of the device, there is a terminal for connection of diagnostic cables (Fig.2).
Figure 2 – Terminal for connection of diagnostic cables
There is a USB Type-C port in the bottom part of the tester, through which the power is supplied
to the tester during the diagnostics of voltage regulators. The USB port serves as well for
connection of the tester to a computer either for software updating or for data copying (Fig.3).

A diagnostic cable for voltage regulators (Fig.4) and adapter cables (Fig.5) for easy connection to
the voltage regulator output terminals are included in the tester set.

The diagnostic cable for voltage regulators (Fig.4) has the following color markings (Table 1):
•Red cable with a clip – B+ – voltage regulator terminal B+ (terminal 30);
•Black cable with a clip – B- – voltage regulator terminal B- (GND, terminal 31);
•Orange cable with a terminal – S(Sense pin) – through this terminal, the voltage
regulator measures the battery voltage and compares it with the alternator/voltage
regulator output voltage. This cable is connected to terminals S of the voltage regulator;
•Red cable with a terminal – IG (Ignition) – the ignition terminal (terminal 15, A, IG);
•White cable with a terminal – FR – through this terminal, the data on the voltage
regulator load are transmitted. The cable connects to FR, DFM, and M terminals of the
voltage regulator;
•Grey cable with a terminal – D+ – the terminal through which the control lamp of the
voltage regulator is connected to terminals D+, L, IL, and 61 of the voltage regulator;
•Yellow cable with a terminal – GC – for connection of the tester to the control channel
of the voltage regulator through voltage regulator terminals COM, SIG, and others;
•Green cables with clips – F1, F2 – for connection of the tester to the brushes of the voltage
regulator or their corresponding terminals: DF, F, FLD;
•Blue cables with clips – ST1, ST2 – for connection of the tester to the stator terminals of
the voltage regulator: P, S, STA, Stator.

The equipment set includes a cable for alternator diagnostics (Fig.6).
Figure 6 – Diagnostic cable for alternators MS-33501
The diagnostic cable (Fig.6) has the following color markings:
•Red clip, big – „В+” – battery positive terminal, alternator output terminal. It is used to
supply power to the tester and read the alternator output voltage;
•Black clip, big – „В-” – battery negative terminal (alternator body);
•Orange clip, small - „S” (Sense pin);
•Red clip, small – „IG” (Ignition);
•White clip, small – „FR”;
•Grey clip, small – „D+”;
•Yellow clip, small – „GC”.
