N.B.
THE DETECTION SHALL BE MADE WITH REGULATOR ACTIVATED.
ALTERNATOR BOSCH TYPE AND EFEL TYPE
EXTERNAL CHARACTERISTICS CONTROL
Make the electrical circuit diagram, proceeding as follows:
maintain, on variable resistive load, a constant voltage of 13.5 V at full excitation and after thermal
stabilisation, which can be achieved through the operation of the alternator to the supply of 90W for 15',
proceed to detect the characteristic values of the external alternator, which must be those indicated in
the respective tables:
