regulator to handle the higher field current and enables it

to absorb the increased inductive voltages of the field

coil with satisfactory contact point life.

The double-contact regulator assembly (fig. 2c) con-

sists of a double contact voltage regulator unit and a field

relay unit. This unit uses two sets of contact points on

the voltage regulator unit to obtain desired field excita-

tion under variable conditions. Internal circuit wiring

diagrams of the double contact regulator are shown in

Figures 3c and 4c.

The transistor regulator (fig. 2c) is an assembly com-

posed principally of transistors, diodes, resistors, a

capacitor, and a thermistor to form a completely static

voltage regulating unit in combination with a conventional

vibrating type field relay.

The transistor is an electrical device which limits the
generator voltage to a preset value by controlling the

generator field current. The diodes, capacitor and re-

sistors act together to aid the transistors in controlling

the generator voltage. This is the only function that the

regulator performs in the charging circuit. The

thermistor provides a temperature-compensated voltage

setting. Wiring diagrams of the transistor regulator are

shown in Figures 3c and 4c.

The voltage at which the generator operates is deter-

mined by the regulator adjustment. The regulator voltage

setting can be adjusted externally by removing a pipe plug

in the cover (fig. 2c) and turning the adjusting arm inside

the regulator. This procedure is explained in the followr

ing section, and permits regulator adjustments without

removing the cover.

Engine compartment wiring harness incorporates sev-

eral fusible links. Each link is identified with its gage

size. A fusible link is a length of special wire (normally

four wire gages smaller than the circuit it is protecting)

used in wiring circuits that are not normally fused, such

as the ignition circuit. The same size wire with a hypalon

insulation must be used when replacing a fusible link.

The links are:

1.
The pigtail lead at the battery positive cable (except

Corvette) is a 14 gage, brown fusible link protecting

the 10 gage battery charging circuit. This wire is an

integral part of the battery cable assembly and serv-

icing requires replacing the complete battery cable

assembly. On Corvette models this link is installed

as a molded splice at the solenoid "Bat" terminal

and servicing requires splicing in a new link.

2.
A 16 gage black fusible link is located at the horn
4.
relay to protect all unfused wiring of 12 gage or

larger. It is installed as a molded splice and serv-

icing requires splicing in a new link.

The generator warning light and field circuitry (16

gage wire) is protected by a fusible link (20 gage

orange wire) used in the "battery feed to voltage

regulator #3 terminal" wire. The link is installed as

a molded splice in the generator and forward lamp

harness and is serviced by splicing in a new 20 gage

wire as required.

The ammeter circuit on all models is protected by

two orange, 20 gage wire fusible links installed as

molded splices in the circuit at the junction block or

the solenoid "Bat" terminal (Corvette only) and at

the horn relay. Each link is serviced by splicing in a

new 20 gage wire as required.

MAINTENANCE AND ADJUSTMENTS

At regular intervals, inspect the terminals for cor-

rosion an4 loose connections, and the wiring for frayed

insulation. Check mounting bolts for tightness. Check the

drive belt for alignment, proper tension and wear. Be-

cause of the higher inertia and load capacity of the rotor

used in A.C. generators, PROPER BELT TENSION is

more critical than on D.C. generators.

Since the Delcotron and its companion regulator are

designed for use on negative polarity systems only, the

following precautions must be observed. Failure to ob-

serve these precautions may result in serious damage to

the charging system.

1.
When installing a battery, always make absolutely

sure the ground polarity of the battery, generator and

regulator is the same.

2.
When connecting a booster battery, make certain to

connect the correct battery terminals together.

3.
When connecting a charger to the battery, connect the

correct charger leads to the battery
%
terminals.

4.
Never operate the generator on an uncontrolled open

above check exceeds 0.2 volts,

excessive resistance
is
indicated in that portion
of
start-

ing circuit
and the
cause
of the
excessive resistance

should
be
located
and

in
order to obtain maxi-

mum efficiency in the circuit.

CAUTION:
Do not
operate
the
starting motor

continuously
for
more than
30
seconds
to
avoid

overheating.

When
the
solenoid fails
to
pull
in, the
trouble may be

due
to
excessive voltage drop in the solenoid control cir-

cuit.
To
check
for
this condition, close
the

and
measure
the
voltage drop between
the
BAT-

TERY terminal of the solenoid and the
SWITCH (S)
termi-

nal
of
the solenoid.
1.
If
this voltage drop exceeds 3.5 volts, excessive

is
indicated

and should be corrected.

2.
If the
voltage drop does not exceed 3.5 volts and the

solenoid does not pull in, measure the voltage availa-

ble
at
the SWITCH terminal
of
the solenoid.

3.
If the
solenoid does

it
should pull
in

whenever the voltage available
at
the SWITCH termi-

nal
is 7.7
volts
or
more. When
the

it
will require
a
somewhat higher voltage
to

STARTING MOTOR AND SOLENOID CHECK

The following checks
may be
made
if the
specific

gravity of the battery
is
1.215
or
higher.

1.
If the
solenoid does
not
pull in, measure the voltage

between
the
switch
(S)
terminal
of the
solenoid
and

ground with the starting switch closed.

CAUTION:
If the
solenoid feels warm, allow
to

cool before checking.

If
the
voltage
is
less than 7.7 volts, check for ex-

cessive resistance
in the
solenoid control circuit.

If
the
voltage exceeds 7.7 volts, remove the starting

motor
and
check
(1)
solenoid current draw,
(2)

starting motor pinion clearance,
and (3)
freedom of

shift lever linkage.

2.
If
the solenoid "chatters" but does not hold in, check

the solenoid
for an
open "hold-in" 'winding. When-

ever
it is
necessary
to
replace
a
starting motor

solenoid, always check starting motor pinion

clearance.

3.
If
motor engages
but
does
not
crank
or

slowly, check
for
excessive resistance
in the ex-

ternal starting circuit, trouble within
the

ELECTRICAL

Any one of the following general complaints may be due

to electrical trouble in the overdrive circuit.

1.
Does not engage.

2.
Does not release.

3.
Does not kickdown from overdrive.

These troubles may be traced and remedied as de-

scribed in the following paragraphs.

1.
Does not engage

a. With the ignition switch on, ground the "KD" ter-

minal of the solenoid relay with a jumper lead.

If the solenoid clicks, the relay and solenoid cir-

cuits are in operating condition. If no click is

heard in the relay, check the fuse and replace if

defective.

b.
If the fuse is good, use a second jumper lead to

connect the "SOL" and "BAT" terminals of the

relay. If a click is now heard in the solenoid, the

relay is probably at fault and should be repaired

or replaced.

c. If the solenoid does not click in Step b, check the

wiring to the No. 4 terminal of the solenoid and

replace if necessary. If the wiring is not defec-

tive,
the trouble is probably in the solenoid. Re-

move the solenoid cover, examine the solenoid

contacts in series with the pull-in winding and

clean if necessary. Test again for clicks, as in

Step b, after replacing solenoid cover and lead

wires.
Replace the solenoid if trouble has not

been corrected.

d. If the relay and solenoid circuits are in good con-

dition as determined in Step a, leave the ignition

switch on and make sure the manual control knob

is in the overdrive position. Ground one and then

the other of the two terminals next to the stem of

the kickdown switch (identified as "SW" and
?fREL"). K the solenoid clicks when one terminal

is grounded but not the other, replace the switch.

If the solenoid does not click when either of the

terminals is grounded, check the wiring between

the relay and the kickdown switch and replace if

defective.

e. If the solenoid clicks as each terminal is grounded

in Step d, ground the governor switch terminal.

If the solenoid clicks, the governor switch may be

defective. If the solenoid does not click, check

the wiring between the kickdown and governor

switches and replace if necessary.

2.
Does not release

a. Remove the connection to the "KD" terminal of

the relay. If this release overdrive, look for a

grounded control circuit between the relay and

governor switch.

b.
If the overdrive is not released in Step a, dis-

connect the lead to the "SOL" terminal of relay.

If this releases the overdrive, replace the relay.

3.
Does not kickdown from overdrive

a. With the engine running, connect a jumper lead

between the No. 6 terminal of the solenoid and

ground. Operate the kickdown switch by hand.

This should stop the engine. If it does, the sole-

noid is probably defective and it should be checked

for dirty ground-out contacts or other defects

within the ground-out circuit of the solenoid (fig.

4B).
Clean the contacts or replace the contact

plate as required.

b.
If the engine does not stop in Step a, ground one

and then the other of the two terminals (Identified

as "IGN" and "SOL") farthest from the sfem of

the kickdown switch. The engine should stop when

one of the two terminals (IGN) is grounded. If

the engine does not stop when the terminal is

grounded, the wiring or connections to the switch

between the switch and coil are defective. When

the btlier terminal (SOL) is grounded, the engine

should stop when the kickdown switch is operated.

If the engine does not stop when the kickdown

switch is operated with the second terminal

grounded, the kickdown switch is defective. If

the trouble is in the kickdown switch, adjust the

linkage to give more travel of the switch rod.

If this does not correct the trouble, replace the

kickdown switch.

If the kickdown switch operates as it should,

check for an open circuit in the wiring between

the kickdown switch and the No. 6 terminal of the

solenoid.

c. If the trouble is not located by the above checks,

the upper contacts of the kickdown switch may not

be opening. To check for this condition, ground

the overdrive control circuit at the governor

switch. This should cause the solenoid to click.

Operate the kickdown switch by hand. This should

cause a second click as the solenoid releases.

If there is no second click, adjust the linkage to

give more travel of the switch rod. If this does

not correct the trouble, replace the kickdown

switch.

axle ratio. LI Range position prevents the trans-

mission from shifting out of first gear.
It is very important that any communication concerning

the Turbo Hydra-Matic always contain the transmission

serial number and that all transmission parts returned

to Chevrolet Motor Division always be tagged with the

transmission serial number.

MAINTENANCE AND ADJUSTMENTS

TRANSMISSION FLUID

Transmission fluid level should be checked with trans-

mission warm and selector lever in "P" Park position,

every time engine oil level is checked or as specified in

Section 0 when engine oil is changed.

CAUTION: Since the Turbo Hydra-Matic trans-

mission is very sensitive to oil level, special

precautions should be taken when checking the

oil level, to insure against an overfifE

Transmission fluid should be changed as specified in

Section 0.

FLUID LEVEL INDICATOR

The fluid level indicator is located in the filler pipe at

the right rear corner of the engine. To bring the fluid

level from the add mark to the full mark add 1 pint.

Fluid level should be to the full mark with transmission

at normal operating temperature. With cold fluid the

level should be at the add mark or slightly below.

SHIFT CONTROL LINKAGE ADJUSTMENT

Adjust linkage as shown below and in Figure 2.

1.
The shift tube and lever assembly must be free in the

mast jacket See Section 9 for alignment of steering

column assembly if necessary.

2.
To check for proper shift linkage adjustment, lift the

transmission selector lever towards the steering

wheel. Allow the selector lever to be positioned in

drive (D) by the transmission detent.

NOTE: Do not use the indicator pointer as a

reference to position the selector lever. When

performing linkage adjustment, pointer is ad-

justed last.

3.
Release the selector lever. The lever should be in-

hibited from engaging low range unless the lever is

lifted.

4.
Lift the selector lever towards the steering wheel,

and allow the lever to be positioned in neutral (N) by

the transmission detent.

5.
Release the selector lever. The lever should now be

inhibited from engaging reverse range unless the

lever is lifted.

6. A properly adjusted linkage will prevent the selector

lever from moving beyond both the neutral detent,

and the drive detent unless the lever is lifted to pass

over the mechanical stop in the steering column.

See schematic diagram.

7.
In the event that an adjustment is required, place the

selector lever in drive (D) position as determined by

the transmission detent. See Steps 2 and 3.

8. Loosen the adjustment swivel at the cross-shaft, and
rotate the transmission lever so that it contacts the

drive stop in the steering column.

9. Tighten the swivel and recheck the adjustment. See

Steps 2 and 6. -

l(h Readjust indicator needle if necessary to agree with

the transmission detent" positions. See Section 9.

11.
Readjust neutral safety switch if necessary to pro-

vide the correct relationship to the transmission de-

tent positions. See Section 12.

12.
When properly adjusted the following conditions must

be met by manual operation of the steering column

shift lever:

a. From reverse to drive position travel, the trans-

mission detent feel must be noted and related to

indicated position on dial.

b.
When in drive and reverse positions, pull lever

rearward (towards steering wheel) and then re-

lease. It must drop back into position with no

restrictions.

NEUTRAL SAFETY SWITCH ADJUSTMENT

The neutral safety switch must be adjusted so that the

car will start in the park or neutral position, but will not

start in the other positions. For replacement refer to

Section 12 of this Manual.

DRAINING AND REFILLING TRANSMISSION

Drain oil immediately after operation before it has had

an opportunity to cool.

To drain oil proceed as follows:

1.
Remove bottom pan attaching screws, pan, and gas-

ket.

2.
Remove oil strainer. Remove "O" ring seal from

pick-up pipe and discard.

3.
Discard strainer if dirty.

4.
Install new "O" ring seal on pick-up pipe and install

strainer and pipe assembly.

5.
Thoroughly clean bottom pan.

6.. Affix new gasket to bottom pan with petroleum jelly.

7.
Install bottom pan with attaching screws and torque

to specifications;

8. If only the pan has been removed, pour approximately

7-1/2 pints of fluid into the transmission. If the

valve body has also been removed use 9-1/2 pints.

After a complete overhaul approximately 19 pints

are required. Be sure container, spout, or funnel is

clean.

9. Start engine and let idle (carburetor off fast idle

step).
Place selector lever in P position and apply

hand brake.

10.
With transmission warm (approximately 150°F), add

fluid to bring level to full mark on indicator.

CAUTION: Do not overfill. Foaming will re-

sult.
