housing.

4.
Move printed circuit away from gauge area and re-

move gauge unit from housing.

5. Remove terminal nuts securing gauge to cover

detach unit.

6. To install, reverse removal procedure.

SEAT SEPARATOR INSTRUMENT CONSOLE

(Fig.
54)
(Fuel,
Ammeter, Temperature, Oil Pressure Gauges,

Low Fuel Warning Unit, and Clock)

1.
Disconnect battery ground cable.

2.
Remove clock shaft knob from face of cluster.

3.
Remove cover retaining screws (4) and cover from

cluster assembly.

Use an alien wrench to remove the two

screws located in the top of the cover below the

instrument console.

4.
Remove four screws retaining gauge mounting plate

to cluster housing.

5. Carefully disengage gauge plate from housing and

disconnect oil pipe and all electrical connections at

rear of gauges.

NOTE:
At this point, with gauge package re-

moval from housing all gauges including the low

fuel warning system may easily be serviced.

6. To install assembly, use reverse of removal

procedure.

OIL PRESSURE INDICATOR

If the light does not come on when the ignition switch

is turned on, or if the light comes on and remains on

after the engine is started, one or more of the following

conditions is indicated.

• Low oil pressure

• Defective wiring or switch

Sending Unit Replacement

1.

GENERATOR INDICATOR

1.
Ignition on, engine not running and indicator light off:

•Indicator bulb is burned out, replace bulb.

•Open circuit or loose connection in the indicator

light circuit.
2.
Indicator light stays on after engine is started:

•Ti indicator light does not go out at engine idle

speed, refer to Charging System Tests in Section

6Y, Engine Electrical.

TEMPERATURE (COOLING SYSTEM) INDICATOR

The temperature indicator circuit consists of two re-

motely located units, indicator lamp and sending unit.

The "indicator lamp, located in the instrument cluster

consists of a single red light which will indicate an over-

heated engine condition.

Engine Sender Unit Replacement

1.
Drain engine cooling system to a level below unit.
2.
Remove sender unit (located in cylinder head near

an exhaust port on L-6 engines and in the inlet mani-

fold near water pump housing on V-8 engines).

3.
Replace unit, refill cooling system and check opera-

tion of unit.

DIRECTIONAL SIGNAL

Directional signal assemblies provide as standard pro-

duction equipment a lane changing feature and hazard

warning system on all model applications. Two different

design switches are used as shown in Figure 55. Major

difference between the two units is that one type has can-

celling and detent springs which are serviceable, other-

wise both units are not repairable and must be replaced

as an assembly in service.

Due to the integral design relationship of the signal

switch and the energy absorbing steering column, refer-

ence should be made to Steering, Section 9 of this manual
whenever any service operations are performed on the

steering column. The directional signal switch replace-

ment procedures covered in this section are intended to

supplement the detail service operations outlined in Sec-

tion 9.

Special note should be taken of the fact that different

signal flasher units are used in Chevrolet models depend-

ent on the number of lamps to be operated. The hazard

warning unit, even though an integral component of the

directional switch assembly, requires the installation of

an additional flasher unit in the fuse panel capable of op-

FUSES AND CIRCUIT BREAKER

A circuit breaker in the light control switch protects

the headlamp circuit, thus eliminating one fuse. A

separate circuit breaker protects the power window,

seat and top circuits. On Corvettes the headlamp motor
circuit is also protected by a separate circuit breaker.

Where current load is too heavy, the circuit breaker

rapidly opens and closes, protecting the circuit until

the cause is found and eliminated.

louses located in the Fuse Panel under the instrument panel are:

Wiper (Chevrolet, Chevelle, and "F" Car) 3AF/AGC 20 Amp.

Back-up Lamp and Gauges. . . 3AG/AGC 10 Amp.
