Test bench MS005/MS005A
3.1. Using the alternator drive control buttons (see position 1 in Figure 26), set the alternator
pulley rotation speed within the range of 100 to 150 rpm.
3.2. Visually assess whether the alternator rotates normally. If there are noises or vibrations
from the alternator indicating mechanical malfunction or incorrect alternator installation,
diagnostics should be stopped by pressing the "Cancel" button.
3.3. To continue the diagnostics, press the "Ok" button.
4. Connect the diagnostic scanner to the OBD II connector of the special cable and try to read data
from the alternator connector.
5. Set the drive speed within the range of 1500 to 3000 rpm.
6. Activate the testing in alternator mode.
6.1. Sequentially increase or decrease the resistance moment (position 5 in Figure 28). At the
same time, the current value "I DC, A" should also increase or decrease proportionally.
6.2. Stop the testing mode by pressing the "Stop" button (position 6 in Figure 28).
7. Stop the alternator drive with the "Stop motor" button. After the alternator drive is completely
stopped, activate the testing in starter mode.
7.1. By setting the torque value, the alternator should start rotating. Increasing or decreasing
the torque moment should proportionally increase or decrease the current value "I DC, A".
7.2. Stop the testing mode by pressing the "Stop" button (position 6 in Figure 28).
8. Exit the diagnostic mode, after which the alternator can be removed from the bench.
