Test bench MS006
**For the Lamp alternator types without voltage control, p. 7.2 is skipped.
7.4. For the C JAPAN and I-ELOOP alternator types, change the set stabilization voltage to OFF
mode. The measured stabilization voltage value should be set within 12 - 12.7 V. Then change
the set stabilization voltage to "ON mode. The measured stabilization voltage value should be
within 14 - 14.5 V.
8. Check the alternator operation under the load as follows:
8.1. Turn the knob ROTATION SPEED to set the rotation value within 2500 – 3000.
8.2. Turn the knob REGULATION GC or press once to set the generation voltage 13.8V. For C-JAPAN
and I-ELOOP alternator types switch ON mode.
8.3. Turn the knob ELECTRICAL LOAD smoothly increase the load to alternator up to maximum.
At this time, the output voltage value should be stable, and the alternating current value in the
circuit B+, I, AC should not exceed 10% from the set load value (e.g., at the load 50A the value of
I, AC should not exceed 5А). At the same time, the current oscillogram (highlighted by red) should
not show the high peak points. The values should range within equal values.
9. To stop the diagnostics, throw off the load from alternator and stop the drive shortly pressing
the knobs ELECTRICAL LOAD and ROTATION SPEED. Now you can dismount the alternator from the
bench.
10. If any of 4.1, 4.5, 5 – 8 steps cannot be completed as described, it means that alternator is out
of order.
WARNING! When the alternator voltage exceeds a permissible value, the protection system
stops the engine. An overvoltage message is displayed on the screen.

6.4. Alternator testing in automatic mode
WARNING! Not available for I-STARS и I-ELOOP alternator types.
1. Follow paragraphs 1 to 5 of section 4.1.
2. Set the direction of rotation in auto test mode menu: "CW" – clockwise; "CCW" – counter-
clockwise. Click on the corresponding icon to change the rotation side of the drive.
3. Press the "AUTO" button. The test bench will start to diagnose the alternator in automatic mode.
The current status of the diagnostic process along with the tested parameters will be displayed.
