KENNEDY thoroughly recommends reading these instructions be ore using the
Timing Light, even i you have used one be ore. Reading these instructions care ully
and understanding them ully will enable you to per orm tasks correctly and will
prevent injury to yoursel or someone else as well as prevent damage to the vehicle
and equipment. For detailed and concise instructions on using this product correctly,
re er to the manu acturer’s workshop manual or the appropriate Haynes service and
repair manual.
SAFETY GUIDELINES
lIf any doubt, contact a qualified auto electrician.
lAlways wear safety goggles to protect your eyes from battery acid, petrol, dust
and dirt flying off moving engine parts.
lAlways wear protective gloves when working with engine components.
lAlways ensure that hands, hair, clothing or cables are well clear of any moving or
hot parts.
lAlways follow the vehicle manufacturer’s recommendation and procedures.
lAlways turn off the ignition of the vehicle before connecting the clamps to the
battery and disconnecting the timing light.
lAlways ensure that the hand brake is on and the vehicle transmission is in Neutral
(manual) or Park (automatic).
lAlways keep children and unauthorised persons away from the working area.
lAlways store the timing light in a safe, dry and child proof location when not in use.
lAlways run the engine in a well ventilated area.
lAlways remember that a flashing timing light “freezes” rotating components. Do not
be tempted to touch an apparently stationary component which is, in fact, rotating.
lNever use the timing lights if they are damaged in any way.
lNever smoke, create sparks or use a naked flame near batteries.
lNever rest tools or metallic items on top of the battery.
lNever touch any ignition components when the ignition is on as very high voltages
are present.
lNever pull the cables or clamps from the battery terminals.
lNever operate in the vicinity of flammable liquids or gases.
lNever place the timing light on the hot engine surface.
lNever modify the timing light in any way or use it for a task for which it is not
designed.
Timing is given in “linear measurement”
or “degrees” relative to the “Top Dead
Centre” (TDC), of the movement of the
piston (see figure 1).
B.T.D.C Before Top Dead Centre. When
the timing is “advanced”, the spark will
occur before the piston reaches the top
of the engine cylinder ensuring that the
full power of the explosion is obtained.
T.D.C Top Dead Centre. The piston is at
its highest point in the cylinder.
A.T.D.C After Top Dead Centre. When
the timing is “retarded”, the spark
occurs after the piston has started to go
down in the cylinder.
LEAD CONNECTIONS (see ig.2)
1. Clamp the inductive pick-up around
the number one (1) spark plug
wire. Make sure the arrow on it is
facing towards the spark plug. Do
not allow the inductive pick-up to
touch the exhaust manifold or
surrounding parts as these areas
become extremely hot and will
damage the inductive pick- up.
2. Connect the RED clamp to the
positive (+) battery terminal.
3. Connect the BLACK clamp to a
secure engine ground such as the
alternator bracket or the engine
block. For safety reasons, do not
use the negative (-) battery terminal
or fuel system components as a
ground connection point.
TIMING ADJUSTMENT
PLEASE NOTE: Be ore adjusting the timing, the “dwell angle” or “gap” should be adjusted on vehicles
itted with contact breaker points.
1. Check manufacturers specifications for correct timing for engine being serviced.
2. Loosen the distributor clamp bolt so that the distributor can be rotated in either direction.
3. Locate engine timing mark and use a rag to clean all grease and dirt from the mark and the pointer. It
may help to use chalk or white paint on the mark to make it more easily seen.
4. tart and run the engine until normal operating temperature is reached. Approximately 15 minutes and
then stop engine.
5. tart the engine and operate at normal idle speed, aiming the timing light towards the timing mark.
6. Trigger the timing light and observe the reading from the timing mark.
7. Compare the reading obtained with the manufacturers specifications. If the timing is not as specified, slowly
rotate the distributor slightly to obtain a correct reading.
8. top the engine.
9. Tighten the distributor clamp bolt.
10. Restart and check the timing.
11. If it is the correct reading, stop the engine and reconnect the vacuum hose.
INTRODUCTION
OPERATING INSTRUCTIONS
“Timing” is the precise moment a spark plug ignites an air and fuel mixture which results
in an explosion delivering maximum power to the engine piston. B.T.D.C
