Figure 23 - Voltage regulator ARE6149P connected to the tester terminals
Connection of voltage regulator ARE6149P has a specific feature. We connect cable F1 to the only
terminal – F. As the actual voltage regulator is B-circuit type, the other cable (F2) must be
connected to terminal B-. Consequently, one of the brushes is permanently connected to B- of
the alternator, while the excitation winding is controlled through terminal B+.
4.2 Diagnostics of Lamp-type voltage regulators
1. Connect the voltage regulator as described in item 4.1.
2. Enter the menu for voltage regulator type selection, select the nominal voltage (12V or 24V)
and activate the test mode for Lamp-type regulators.
3. Upon activation, stabilizing voltage must set in the range from 14 to14.8 volts for 12V voltage
regulators and from 28 to 29.8 volts - for 24V regulators, and must correspond to the voltage
regulator characteristics.
4. Turn off simulation of the alternator rotation by pressing K15 and setting rpm to zero – the
control lamp indicator (Fig.10, n.3) will light up. Press K15 again to restart simulation, the control
lamp indicator must go out.
5. 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.
