GENERAL DESCRIPTION

The standard instrument cluster on all models contains

seven circular housings consisting of: a speedometer;

fuel gauge; oil pressure, generator and temperature indi-

cators; right and left directional signal indicators; brake

warning and high beam indicators; and includes a clock

on deluxe models. An optionally available instrument

cluster provides special instrumentation which includes

in addition to the speedometer and clock: a tachometer;

fuel, oil pressure, ammeter and engine temperature

gauges; which replace the standard fuel gauge and indi-

cator lights. The brake warning indicator is relocated

to the tachometer dial face and the high beam and direc-

tional indicators are positioned in the speedometer dial

face.

Instrument cluster removal is recommended before at-

tempting to service the printed circuit and gauges even

though some units may be accessible from behind the

cluster. Limited working space under the instrument

panel increases the possibility of electrical malfunctions

due to poor connections, and damaged or improperly in-

stalled printed circuit. The printed circuit is service-

able but not repairable and requires complete
replacement.

The brake warning light serves a dual purpose. It

functions as an indicator when the parking brake is ap-

plied and also warns if a malfunction (loss of hydraulic

pressure) should occur in the brake system. The two

separate switches, which provide the signal to operate the

indicator, are located at the parking brake support and in

the hydraulic brake line at the master cylinder. Service

of the brake pressure, differential switch unit at the

master cylinder is described in Section 5 of this manual.

All indicator and cluster illumihating lamps may be

replaced without removing the cluster from the vehicle.

The bulbs are installed in plastic holders which lock into

the cluster housing and make contact with the printed

circuit. An instrument lamp is used to illuminate the

ignition switch. A special fibre optic lucite wiring

transmits light from the lamp to the switch.

Regular maintenance is not required on the instrument

cluster or its components other than maintaining clean,

tight electrical connections, replacing defective parts and

keeping the speedometer cable properly lubricated.
