Device for testing new generation alternators.

The device can be used to make diagnoses of the charging circuit on vehicles with alternator with charging current supplied by the ECU. The device, by means of specific communication protocols, simulates the command from the system ECU. The device is able perform tests on alternators mounted on the vehicle or on test benches in the workshop.

The main manufacturers currently using this type of alternator are:
AUDI, BMW, CITROËN, FORD, JAGUAR, LAND-ROVER, MAZDA, MERCEDES, MINI, PEUGEOT, RENAULT, SEAT, SKODA, TOYOTA, VOLVO and VOLKSWAGEN.

COMPATIBLE WITH CON TROL STANDA RDS :
1. COM - LIN, BSS(BSD) interface
2. SIG - FORD
3. P-D Mazda
4. L -RVC - GM
5. RLO - Toyota
6. Others – programmable PWM generators  

The device powers on automatically after connecting power supply to B+ and B- ports. The test subject selection menu will appear. Select the required parameter the up and down arrow keys and press OK what moves in the test mode.
After pressing the knob, the display will present the following information:
• voltage of the tested circuit (large digits)
• required voltage (small digits on the top of the display)
• alternator load DF/DFM [%]  

The RC and M cables should be connected to the correct pins in the voltage regulator’s socket. Some of the regulators require connecting other signals (usually B+) with a separate cable to operate correctly. The M cable can be left disconnected in the COM mode. In test mode by selecting the arrows up and down will change the value of a given voltage. It should be monitored whether changing the required voltage causes the correspondent change in the alternator/regulator output, and whether the DFM reading matches the actual state.
