DISTRIBUTOR OFF-ENGINE TEST
The distributor's centrifugal and vacuum advance can
be checked in a distributor testing machine or synchro-
scope specially adapted or designed to accommodate this
type distributor. However, since this involves removing
the distributor from the engine, this test may be post-
poned until other system checks have been made. A dwell
reading cannot be obtained on this distributor and it is not
likely that the centrifugal or vacuum advance will be a
cause of trouble.

COMPONENT CHECKS (Figs. \7\ and 18i)
With the two transistors separated from the assembly,
an ohmmeter may be used to check the transistors and
components on the panel board for defects. An ohmmeter
having a 1-1/2 volt cell, which is the type usually found
in service stations, is recommended. The low range
scale on the ohmmeter should be used except where
specified otherwise.
A 25 watt soldering gun is recommended, and a 60% tin
40%
 lead solder should be used when re-soldering. Avoid
excessive heat which may damage the panel board. Chip
away any epoxy involved, and apply new epoxy which is
commercially available.
In order to check the panel board assembly, it is
necessary to unsolder at the locations indicated in Fig-
ure 18i the two capacitors C2 and C3. In all of the fol-
lowing checks, connect the ohmmeter as shown and then
reverse the ohmmeter leads to obtain two readings. The
amplifier circuitry is shown in Figure 19i.
1.
 Transistors TR1 and TR2: Check each transistor by
referring to Figure 20i. If both readings in Step 1
are zero, the transistor is shorted. If both readings
in Step 2 are zero, the transistor is shorted; and if
both readings are infinite, the transistor is open.
Interpret Step 3 the same as Step 2.
2.
 Trigger Transistor TR3:
 11
 both readings in Step 1
are zero, the transistor is shorted. If both readings
in Step 2 are zero, the transistor is shorted; and if
both readings are infinite, the transistor is open.
Interpret Step 3 the same as Step 2.
3.
 Diode Dl: 11 both readings are zero, the diode is
shorted; and if both readings are infinite, the diode
is open.
4.
 Capacitor Cl: If both readings are zero, the capaci-
tor is shorted.

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.
