Chrysler 1956 Windsor - Inspecting the Current and Voltage Regulator; Normalizing Regulator Temperature

Inspecting the Current an d Voltage Regulator
Remove regulator cover. Check for the follow~
ing conditio ns:
(1) Loose or broken connections, resulting
from poor
so ld ering when previously serv-
iced, or rough handling.
(2) Evidence of
burning or abnormal high tem-
peratu res at the coils, con ta ct points, ins u-
lation, or the fl exible arm to which regu-
lator contacts are mounted.
(3) Improperly installed
armature springs, dis-
tor ted s pring hangers, bent armatures ,
yokes
or hinges.
(4) Evidence of moisture
or corrosion in reg-
ulator.
If any of the above conditions are apparent,
or if regulator is in a generally poor condition,
replace
the regulator unit.
Before
testiOR the regulator, it is absolutely
essential
that the circuit resistance and the bat-
tery be tested. (See "Starter Circuit Re sist -
ance"
an d "Starter C urrent Draw Test.") Test
the battery by following the procedure outlined
under "BAT TERY TESTING." Make all nec-
essary corrections to return the charging sys-
tem to normal, such as cleaning and tightening
all loose connections, generator brackets and
regulator base screws.
If the hydrometer test indicates that the bat-
tery is below 1.275 specific gravity, the battery
should be charged. If the battery is defective, it
should be replaced. This is necessary when test -
ing a I'egulator so that accurate test results will
be obtained.

To normalize regulator temperature, proceed as
follows:
Connect a test ammeter in series between the
battery lead and the regulator "BAT" terminal.
Connect a tegt voltmeter from the regulator
"BAT" terminal to ground. Connect a variable
resistance across
the battery.
Start the engine. Adjust the engine speed to
1,500 rpm and observe the test ammeter.
Adjust the variable resi stanc e to obtain a
load of
10 amperes. Maintain this 10 ampere
load for 15 minutes in or der to normalize the
regulator temperature with 10 amperes flowing.
NOTE: When testing the voltage regulator, it
is necessary that the cover be in place and that
