4.4 Diagnostics of voltage regulators of C JAPAN type
1. Connect the voltage regulator as described in item 4.1.
2. Select and activate the test mode (Fig.9) for regulators of C JAPAN type.
3. In diagnostic mode the stabilizing voltage must set in the range from 14 to 14.5 volts.
4. Press K15 and set rpm to zero to stop simulation of the alternator rotation. The control lamp
indicator (Fig.10, n.10) must light up. Press K15 once again to turn the simulation on – the control
lamp indicator will go out.
5. Switch the preset stabilizing voltage to OFF. The measured stabilizing voltage must set in the
range from 12 to 12.7 volts.
6. If the voltage regulator is equipped with terminal S, press SENSE to check its operability – the
stabilizing voltage must increase. Press SENSE once again, the stabilizing voltage must decrease
to its initial values.
7. Press BACK to exit the test mode. Disconnect the clips from the voltage regulator.
8. Failure to perform as described in sub-items 3-5 signals the voltage regulator malfunction.
4.5 Diagnostics of voltage regulators of SIG and P/D types
1. Connect the voltage regulator as described in item 4.1
2. Enter the menu for voltage regulator type selection (Fig.9), select the nominal voltage and
activate the test mode that corresponds to the type of the tested voltage regulator.
3. Upon diagnostic mode activation, the stabilizing voltage must set at 13.8V, the allowable
deviation is ±0,2V.
4. Adjust the preset stabilizing voltage in the range from 13.2 to 14.5 volts. The measured voltage
must vary in proportion to the preset one.
5. Press BACK to exit the test mode. Disconnect the clips from the voltage regulator.
6. Failure to perform as described in sub-items 3-4 signals the voltage regulator malfunction.
4.6 Diagnostics of 12/24V voltage regulators of COM type
1. Connect the voltage regulator as described in item 4.1.
