Test bench MS005/MS005A
7 - Control of the load on the alternator, the value is set in percentage of the value set in menu
item 4 of Figure 22.
8 - Control of the alternator drive rotation frequency.
9 - Control of the alternator rotation direction. Usually, alternators rotate clockwise (viewed from
the pulley side).
10 - Button to stop the diagnostic process.
"K15 U V" – Ignition circuit voltage value (K15).
"K15 I mA" – Ignition circuit current value (K15).
"Duty %" - Duty cycle of the signal received via channels FR, DFM, M (degree of rotor winding
activation).
"Frequency Hz" - Frequency value of the signal received via channels FR, DFM, M.
"Speed RPM" - Alternator revolutions measured by the regulator.
"Lamp voltage V" – Voltage value on the control lamp.
"Lamp current mA" – Current strength value on the control lamp.
"I AC, A" – Alternating current value in the B+ circuit.
"I DC, A" – Direct current value in the B+ circuit.
"U DC, V" – Voltage value at terminal B+.
"Pulley RPM" – Rotation frequency on the alternator pulley. If the pulley size is not specified in
menu item 8 of Figure 22, the drive revolution value is displayed.
"Temp. °C" – Maximum temperature value of the diagnosed unit captured by the thermal
imaging camera.
On the diagnostics screen of COM 12V, 24V type alternators (see Figure 24), the following
distinctive information is displayed:
"Status" – indicator of the alternator connection status.
"COM port" – indicator of the voltage regulator protocol version: BSS, LIN1, or LIN2.
"ID" – identification number of the voltage regulator.
"COM speed" – indicator of data transmission speed from the control unit to the voltage regulator.
This parameter is displayed for alternators controlled by the LIN protocol. The following speed
values are possible:
• L – 2400 Baud (low);
• M – 9600 Baud (medium);
• H – 19200 Baud (high).
