2.1 Test modes menu
Upon entering the test mode for voltage regulators, the following information will appear on
the screen (Fig.10):
Figure 10 - Diagnostic screen information
1 – Preset stabilizing voltage (for controlled voltage regulators);
2 – Preset rpm (this parameter will not be displayed in alternator test mode);
3* – Button to check the SENSE terminal through which the voltage regulator measures the
battery voltage (red indication: the voltage across SENSE is lower by 0.5V-0.7V than the voltage
across B+);
4 - Duty cycle of PWM signal received through FR channel (the proportion of the rotor winding
“on” time);
5 – Measured stabilizing voltage;
