Il. CHECKING THE REGULATED TENSION OF THE REGULATORS
CHARACTERISTICS
- Two-stage voltage regulator :
Ref : DUCELLIER 8379 A, PARIS-RHONE AYC 2114 and AYC 2117.
SEV-MARCHAL F. 14 V 72717102
These voltage regulators determine the intensity of the current in the alternator inductor in order to maintain a
constant regulated voltage at the battery terminals.

CHECKING THE REGULATED VOLTAGE

Connect up as per diagram below, using
a voltmeter V, an ammeter A and a rheostat,
or better still, using a
combined
o voltmeter/ammeter/ rheostat )).
Start engine, and let it idle.
Switch off the ignition, and immediately switch it back on in
order to demagnetize
the voltage regulator.
Accelerate the engine so as to reach the adjustment speed for the alternator. Actuate the rheostat, smoothly
without turning it back,
in order to increase the current supplied by the alternator, and read the corresponding
voltage.
Take several measurements of regulated tension, and check that the values obtained are between 13 and 14.2 volts,
taking into account the correction value due to the temperature. If the readings are not correct, replace voltage
regulator.
