The VOLTS position is used to test the cranking and charging systems in the vehicle.

AND

TEST

PROCEDURES:

The following information will serve as a

general guide for making charging system

tests.

Before making VOLTS tests:

Check the fan belt--it should be tensioned

according to the manufacturer's specifications.

Check the generator or alternator pulley and

mounting bolts. They should be tight.

VOLTS

TEST

l. Remove the high tension lead from the

center of the distributor cap and ground it by

placing the loose end so it touches the engine

or frame.

2. Connect the test leads as shown in Fig. 1.

Set the slide switch knob to OTHER TESTS and

the Function Selector Knob to VOLTS.

3. Operate the starter for 10 seconds and ob-

serve the cranking voltage on the 0-16 Volts

scale,

A steady reading of more than 9.6 volts

indicates that the battery, cables, and starter

system are in good condition.

CHARGING SYSTEM

VOLTS TEST

1. Connect the test leads as shown in Fig. 1.

Set the slide switch knob to OTHER TESTS and

the Function Selector Knob to VOLTS.

Start the engine.

Allow it to run a few

minutes at 1500 to 2000 RPM. Observe

the reading on the 0 - 16 volt scale.

The pointer should be between 13.8 and

15.2 volts with or without headlights and

Make sure that the charging system wiring and

the battery cables are in good condition and

that connections are tight.

Make sure the

battery is clean and that the liquid level in

each cell is above the plates.

The engine and all parts of the charging system

should be at normal operating temperature be-

fore making any electrical tests. If the engine

is cold, operate the engine at idle speed for at

least 15 minutes before making any tests.

4. A reading below 9.6 volts could be caused by

a battery that is defective or not fully charged.

Fully charge the battery and repeat the test.

the reading is still below 9.6 volts, either the

battery or starter is defective.

5. A fluctuating voltage reading is indicative

of adefect in the starter or battery or in the

battery-starter wiring circuit.

Refer to page

7 (POINTS-LOW VOLTAGE SCALE) for trouble

shooting voltage drops in the battery~starter

wiring circuit.

Replace or repair any defective parts as required

to restore cranking system to proper operation.

6. Replace the high tension lead in the center

of the distributor cap.

Readings lower than

13.8 indicate either a worn out battery,

defective generator or alternator, defec-

tive or improperly adjusted voltage regu~

Readings above 15.2 are indicative of a

defective or improperly adjusted voltage

regulator.

Replace, repair or adjust the defective

part as required.
