INTRODUCTION
Thank you for choosing the product by ТМ MSG Equipment.
The actual Manual provides operation instructions for health assessment of automotive starters
based on the parameters obtained during the unit diagnosis using tester MS016 and cable
MS-33503.
1. PURPOSE
The purpose of diagnostic cable MS-33503 is to provide the connection between the tester and an
automotive unit, whether it is tested directly on a car or on the test bench that provides its fixation
and power supply.
Using the tester, we can register both: a voltage across starter terminals 31, 30, 50, 45 and a current
across terminal 30 during the engine start. The measured parameters are displayed on the tester
screen as diagrams. In addition, the maximum and minimum values are displayed numerically.
This information helps recognize problems with the starter, battery, or wiring.
2. CABLE DESCRIPTION
Diagnostic cable MS-33503 (Fig.1) has four crocodile clips for connection to the starter terminals
and one current sensor (Fig.2).
The color marking of the cable is as follows:
•Red clip “30” is for connection to starter terminal 30, which in its turn, is connected to the
battery "+".
•Black clip “31” is for connection to a starter frame (GND to a frame).
•Blue clip “50” is used for connection to the solenoid starter terminal where a starting switch
wire is connected.
•Yellow clip “45” is used for connection to the solenoid starter terminal where a power cable
of the starter electric motor is connected.
The current sensor is latched to the power cable connected to terminal 30.

3. TESTER MENU
The activation of the test mode for starters on tester MS016 requires us to connect cableMS-33503
and supply power to the USB Type-C port from either a power unit or a power bank. If it is powered
by the battery alone, a message instructing to connect via the USB will be displayed.

The following information will appear on the tester screen on activation of the test mode (Fig.3):
1 – a field for a graphical display of test results;
2 – buttons for graph time-scale zooming;

5 – maximum and minimum voltage across terminal 45;
6 – maximum and minimum voltage across terminal 50.
On the left and right fields, there are invisible buttons to move through the diagram.

4. INTENDED USAGE
4.1. Safety requirements
Only specially trained persons instructed in operational safety are qualified to work with certain
types of test benches.
4.2. Starter diagnostics
Steps to perform:
1. Connect cable MS-33503 to tester MS016 and apply power to the tester via the USB port.
2. Once the tester is on and the test mode for starters loaded, attach the diagnostic cable clips to
the starter terminals. The sensor should be fixed on the power cable connected to terminal 30 of
the starter so that the direction arrow on the sensor interior would point to the starter.

3. Start the engine. After 5 seconds, cut it off.
4. Wait for the test results to be displayed on the tester screen.

5. Based on the voltage and current changes shown on the diagram, we can evaluate the starter
technical state and assume a possible cause of malfunction, for example:
•A heavy voltage drop across terminal 30 is indicative of the battery’s poor state.
•A heavy voltage drop across terminal 45 is indicative of the starter solenoid problem.
•Strong current ripples on the diagram signal a problem with the electric motor of a starter.
•If a start-up current across terminal 30 is much higher than a nominal one while a voltage
drop is moderate, it betrays the engine problem.
•If a start-up current is lower than a nominal one while a voltage drop across terminal 30 is
heavy, it betrays a poor state of the wiring.

Dziękujemy za wybór produktów MSG Equipment.
Niniejsza instrukcja zawiera informacje na temat używania testera MS016 i kabla diagnostycznego
MS-33503 do rejestrowania parametrów diagnostycznych w celu ustalenia stanu technicznego
rozrusznika samochodu.
1. PRZEZNACZENIE
Kabel diagnostyczny MS-33503 został stworzony do współpracy z testerem MS016 i jest
przeznaczony do diagnozowania rozruszników w samochodzie bez demontażu lub na stanowisku
zapewniającym zablokowanie i zasilanie rozrusznika.
Tester umożliwia zapisanie wartości napięć na klemach rozrusznika: 31, 30, 50, 45 i prądu na klemie
30 podczas rozruchu silnika. Wynik wykonanych pomiarów jest wyświetlany na ekranie testera w
postaci wykresu. Dodatkowo wyświetlane są w postaci liczbowej minimalne i maksymalne wartości
zmierzonych parametrów. Informacje te pozwalają zidentyfikować nieprawidłowości w działaniu
rozrusznika, akumulatora lub okablowania.
2. OPIS KABLA
Kabel Diagnostyczny MS-33503 (rys. 1) zawiera cztery zaciski krokodylkowe i jeden czujnik prądu,
które są podłączane do klem rozrusznika p. rys.2.
Oznaczenia kolorystyczne kabla:
•Czerwony zacisk „30” - podłączany do klemy 30 rozrusznika, która jest podłączona do klemy
„+” akumulatora.
•Czarny zacisk „31” - masa, podłączany do obudowy rozrusznika.
•Niebieski zacisk „50” - podłączany do klemy elektromagnesu rozrusznika, do którego
podłączony jest przewód z przekaźnika rozruchowego.
•Żółty zacisk „45” - podłączany do klemy elektromagnesu rozrusznika, do którego podłączony
jest przewód zasilający silnika elektrycznego rozrusznika.
Czujnik prądu jest umieszczony na przewodzie zasilającym prowadzącym do klemy 30.
