These
voltage regulators
determine the

of
the
current in
the alternator inductor
in order to mairitain

Connect up
as per diagram
below,
using
a
voitmeter
V,
on ammeter A and a
rheostat,
or better
still, using a
combined
«
voltmeter/ammeter/rheostat».
Start engine, and Jet
it
idle.
Switch
off the
ignition, and
immediately switch it
back
on
in
order to demognetize
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.
