Checking The Alternator Output; Checking The Voltage Regulator - CITROEN 2001 BERLINGO Handbook

CHARGING CIRCUIT - ALTERNATOR WITH MONO-FUNCTION REGULATOR
D1AP01SC

CHECKING THE ALTERNATOR OUTPUT

Connect as shown in the diagram opposite, using an ammeter (A), a
voltmeter (V), and a rheostat (R) or a Volt/Ammeter/Rheostat combination.
Adjust the engine speed (table opposite) and rheostat charge
according to the vehicle's equipment specification in order to obtain
U = 13.5 V.
Reminder : The excitation energising current will flow through the
warning lamp - check that the warning lamp comes on when the
ignition is switched on. It must go out when the engine has started
(accelerate slightly).

CHECKING THE VOLTAGE REGULATOR

the rheostat to zero and disconnect all the electrical consumers.
Display 5000 alternator rpm. If U alternator is > 14.7 V, the regulator is
faulty.Set
Note : These tests should be performed with the engine hot and the
battery fully charged.
