The current regulator unit is built with
a bi-metal hinge on the armature. This hinge
exerts an additional tension on the armature
when the unit is cold and in- creases the
current necessary to vibrate the contacts.
This increases the available output when the
generator and regulator are cold without
danger of overheating under prolonged opera-
tion.
Operation Test
Check the wiring to see that it is properly
connected to the generator.
Make sure the generator operates correctly
without the regulator in the circuit.
Remove the armature and battery leads from
the regulator and connect an ammeter between
them. Remove the field lead from the regula-
tor and while operating at idle speed, touch
the field lead to the regulator base.
Increase the speed slowly, noting the charg-
ing rate. DO NOT INCREASE THE OUTPUT ABOVE
THE RATED OUTPUT OF THE GENERATOR. If the
generator output will not build up, inspect
the wiring harness for shorts and opens and
remove the generator for an overhaul.
Make sure the regulator is the correct
type for use with the generator.
Check the specific gravity and terminal
voltage of the battery. If the battery is not
up to specifications, substitute temporarily
for test purposes a fully charged battery of
the same type and capacity.
Inspect the wiring between the generator,
regulator,
and battery for broken wires and high resis-
tance connections. Pay special attention to
the ground connecLions at all three units.
Connect a reliable ammeter with one ampere
graduations in series with the regulator "B"
terminal and the lead removed from this
terminal. Run the generator at a medium speed
and turn on lights or accessories until the
ammeter shows one-half of the maximum charg-
ing rate. At this charging rate, measure
the voltage drop between the following points
using an accurate voltmeter graduated in .1
volt divisions. The voltmeter should not show
a reading above the maximum noted.
Generator "A" terminal to regulator "A"
terminal—.1 volt max.
Generator "F" terminal to regulator "F"
terminal-.05 volt max.
Battery terminal to regulator "B" terminal—
.1 volt max.
Regulator ground screw to generator frame—
.03 volt max.
Regulator ground screw to battery ground
post—.03 volt max.
Generator frame to battery ground post—.03
volt max.

Winding)

regulator "B" terminal and the lead removed
from the terminal. Connect an accurate volt-
