1. DESCRIPTION
MSG MS004 COM is a table multifunctional test bench. The equipment is used for quick and
quality diagnostics of starters, alternators and voltage regulators without applying any additional
measuring devices.
The test bench possesses high power, thus, units can be diagnosed under different loads. The
equipment has small dimensions, it can be placed both in small service centers and big shops
specialized in selling equipment.
The bench includes the following diagnostic functions: testing of 12V and 24V alternators under load,
12V and 24V voltage regulators, 12V and 24V starters in idle running mode. The device carries out
testing of different alternators under load up to 100A. Power supply is single-phase 220V. Connection
of the 2nd battery is conducted from outside to the terminals on the bench body to achieve power
supply of 24V for more convenient connection. Thus, usage of the 2nd battery is optional.
New algorithms of testing have been implemented, meter accuracy has also been improved.

3. RECEIPT AND INSPECTION
Check the set received. It must contain:
• test bench
• 2 cables for external battery connection (Fig. 19)
• wires to connect an alternator, starter, voltage regulator to the bench sockets
• User Manual
Inspect the test bench for existence of damage. If it is found, please contact either the manufacturer
or trade representative before launching the equipment.
WARNING! In case of obvious damage, use of equipment is forbidden.
Mounting face consists of (Fig. 2):
- Chain fixer 1
- Chain 2
- Belts 3,4
- Covers 5 (battery box cover 1).
The chain fixer (1) is used to latch the chain (2).
The belts (3) and (4) are used to transfer engine torque of the bench on a tested pulley of an
alternator.
The battery 1 is placed under the cover (5).

Button 6 is specified as STOP. It is used for emergency deactivation of the bench.
Button 7 is specified as ON/OFF. It is used for activation/deactivation of the bench. When button 6
is on, button 7 is out of operation.
Power cable 8 is specified as В-. It is used to connect power negative potential of an alternator or
starter.
Power cable 9 is specified as В+. It is used to connect power positive potential of an alternator or
starter.
