CHARGING CIRCUIT - ALTERNATOR WITH MONO-FUNCTION REGULATOR

D1AP025C
A : Ammeter
B : Battery
G : Generator
L : Warning lamp
K1 and K2 : Switch
R : Electric charge
S : Shunt 200mV/200A
V : Voltmeter
1 : Alternator.
Connect as shown in the diagram opposite, using an ammeter (A), a voltmeter (V), and a rheostat (R)
or a Volt/Ammeter/Rheostat combination.
Referring to the vehicle's equipment specification (see table opposite), adjust the engine speed and
rheostat charge to obtain U=13.5V.
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 should go out when the engine has started (accele-
rate slightly).
Set the rheostat to zero and disconnect all the electrical consumers.
Display 3000 alternator rpm. If U alternator is > 14.7 V, the regulator is faulty.
Note: These tests should be performed with the engine hot and the battery fully charged.
Method of reading the alternator speed
Fit a reflecting shim on the pulley of the alternator.
Adjust a stroboscope to the frequency equivalent to the control speed.
(e.g. 2000 rpm = 2000/60 = 83 Hz)
Adjust the engine speed so that the shim appears fixed.
