• Se-t the slide swi.-tch knob to-OTHER TESl-S
and the Function Selector Knob to POI NTS.
NOTE: Remove the distributor cap and
inspect the contact points. If
they are blued, blackened, or
pitted, they should be replaced.
Normal used contact points are
light gray in color. If the con-
tact points pass the visual in-
spection, proceed as follows:
3. Replace the distributor cap and 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.
NOTE: When testing a vehicle with dual
points, alternately block one set
of points open with a piece of in-
sulating material while the other
set is being tested.
4. TURN THE IGNITION KEY ON. If the
meter reads near full scale right, the points
are open. Crank the engine with the igni-
tion key or an external starting switch a
fraction of a revolution at a time until the
meter reads in the left hand area of the
scale. The points are now closed.
The points may be defective or the following
faults may exist:
Poor distri butor ground.
Poor connection on the primary
lead from the distributor to the
ignition coil.
Defective distributor lead.
Misaligned points.
Correct the defect, and repeat the test.
